Three Dallas Schools Make Newsweek’s Best 100 High Schools List – Tag High School is #1!

Wednesday, September 24th, 2008

In their May 8, 2006, issue, Newsweek listed their Best 100 Public Schools across the nation. They ranked the schools using a ratio of the number of Advanced Placement (AP) and/or International Baccalaureate tests taken by all students within a school, divided by the number of graduating seniors. The 2006 list was based on the 2004-2005 school year. Their aim is to acknowledge those schools that do the best job of preparing average students for college, regardless of their economic background.

Three Dallas schools made the list with one taking top honors. Dallas schools’ Highland Park High School weighed in at number 18 with a ratio of 4.735. Dallas schools’ Science and Engineering Magnet took honors at number eight with a ratio of 6.275. Dallas schools’ Talented and Gifted (TAG) High School had a 14.128 ratio and ranked number ONE! What an achievement for the Dallas schools.

Located near downtown Dallas in an impoverished neighborhood, TAG exemplifies how a school can meet the Dallas schools’ goals of providing an excellent education for each and every child. The racially mixed student body receives a high-level of learning that challenges each child to achieve. TAG focuses on getting students into college through AP courses, providing the same opportunities to its students as the wealthy private schools.

Some educators refer to schools like Dallas schools’ TAG as a boutique school, catering to special interest while ignoring course variety. Educators, including those in the Dallas schools, have been demanding reform for over 10 years; yet, they cannot agree on what works. In the ‘80s, the thought was to make all students college ready through a rigorous core curriculum. In the ‘90s, school choice and testing became the norm. Now, some are calling for dumping the entire public school system; while others see smaller schools, class size, and a boutique focus as optimum.

Even when a plan is working as it is in Dallas schools’ TAG High School, opposition still rears its ugly head. Some believe that the smaller school loses the social acclimation that the larger high schools provide. They say that maintaining quality is difficult and the coursework lacks substance. Proponents of Dallas schools’ TAG say that these Dallas Schools’ students get more teacher and counselor attention and the children are less likely to get lost in the crowd, which gives the students an edge.

TAG is one of the Dallas schools that is committed to helping students achieve their best, encouraging each and every student to aim high. They stress the importance of attending college and try to make the AP as much a part of students’ lives as music or hanging out with their friends. While only 30 percent of high school students across the nation take any AP courses at all, each TAG student is required to take at least one, with most students taking more.

Dallas schools’ TAG and other boutique schools like it have increased the number of minorities taking AP courses, increasing their chances to attend college. According to the College Board, which administers the AP, four times as many Hispanics and three times as many Blacks took AP courses in 2005, as compared to 10 years ago.

Newsweek cited Dallas schools’ TAG student Fanny Frausto, age 18, who has taken 16 AP courses and scored high on many of them. She scored a five on her final three-hour exam. Her transcript is definitely atypical for a public high school student, showing a seemingly impossible schedule of classes. She attends MIT on scholarship in the fall of 2006.

Dallas schools’ teachers at TAG go the extra mile for their students. They assist the youth in learning to meet deadlines, constructing essays and organizing their time, managing workloads, and dealing with the tension and nervousness students may feel during testing.

Schools that consistently have high achieving students and programs were not included in Newsweek’s list. Their ratio formula only measures test participation, rather than testing success. Also, due to inconsistencies, the formula does not include drop out rates or state testing scores.

Schools And Services In Dallas Schools

Wednesday, September 24th, 2008

Perhaps one of the most famous cities in the state of Texas, Dallas has many things to recommend it. From the beautiful downtown architecture to the Dallas Cowboys football team, it seems that everything Dallas is wonderful. This includes the Dallas Schools.

Dallas Schools honored 13 schools as “exemplary” and 67 as “recognized” this past February, at an IBM Corporation-sponsored dinner. No other urban school district in Texas had a larger number of exemplary and recognized schools in 2006. In order to be rated exemplary, 90% of all students in Dallas Schools must pass all subject areas of the TAKS, officially known as the Texas Assessment of Knowledge and Skills test. To earn a “recognized” status, 70% of all students in Dallas Schools must pass all subject areas. “The students, teachers, administrators, and parents who worked hard to achieve these high Texas Education Agency rankings deserve applause and congratulations,” said Dallas Schools’ General Superintendent Michael Hinojosa. “They are an inspiration to all of us.”

Improvements continue to multiply throughout Dallas Schools. This past February, additional funding was received from a new arts coalition that will allow for 140 new certified music and art teachers. These teachers will be hired by the Dallas Schools’ district over the next 6 years, including 60 who have already been hired. And by 2009 the district plans to have all Elementary Dallas Schools offering 45 minutes of art and music each week. The Wallace Foundation, one of the members of this arts coalition, will give $8 million during the next three years to Big Thought. Big Thought is a Dallas-based nonprofit arts group, which will help establish the Dallas Arts Learning Initiative. This initiative seeks to increase the amount and quality of arts education students in Dallas Schools will receive.

In addition, the Dallas Schools’ Talented and Gifted magnet and the School of Science and Engineering have been named the two top high schools in the country by Newsweek Magazine. It is the second straight year that the Talented and Gifted magnet (TAG) has earned the honor. “This is a credit to everyone involved with both schools,” said Hinojosa. “These schools are setting the example for others in both the district and the rest of the nation.” The Science and Engineering magnet (SEM) moved from 8th on the list last year to 2nd in 2006. Also, during the last five years, the Dallas Schools’ Science and Engineering magnet has been the number one in the nation for minorities passing Calculus AB and BC exams regardless of size, and the number one school in the world for students passing Calculus AB. “This is the accumulation of several years of extraordinary work by the students and staff affiliated with the school,” said SEM principal Richard White. “We have had a healthy competition for years with the TAG Magnet, and now that both schools are named the best in the county, everyone has benefited, especially the students.”

Indeed, Dallas Schools are something to get excited about. From efforts to expand services at the elementary level, to nationally and globally recognized schools, the opportunities abound for the students of Dallas Schools. In an era of budget cuts and high-stakes testing, Dallas Schools show some remarkable successes.

Foundation Supports Student Achievement In Denver Schools

Wednesday, September 24th, 2008

The Denver Public School Foundation is a “portal” for community and business philanthropy for the Denver schools. Originally started in 1984, it played a passive role in the Denver schools, until it was revitalized in 2002.

The purpose of the Denver schools’ foundation is to raise and manage funds in support of the district’s ambitious plan to improve student achievement. The Denver schools leadership develops the funding areas, and the foundation drives community investment and builds partnerships with local businesses. The price tag for improving student academic achievement is much higher than the available monies provided through annual city, state and federal funding.

During the 2005-2006 school year, the foundation’s accomplishments show it to be a vital arm of the Denver schools’ scholastic achievement initiative. Here are the major highlights:

• The foundation raised $750,000 to implement the first Principals’ Institute that was held in June 2006. Leadership training, designed to improve student achievement, was provided to 130 Denver schools’ principals, and new strategies were developed by the principals to transform their schools into effective learning organizations. The Denver schools principals will continue to be supported in their objectives in 2006-2007 by attending monthly professional development sessions that began in August.

• The foundation raised $250,000 to implement DPS Success, which provides supplemental instruction in math and literacy to students in grades three through ten. During the 2005-2006 school year, 558 teachers provided extra tutoring instruction to approximately 8,400 students in 82 schools.

• The School Partners Program was launched with $250,000 raised by the foundation. The program will create tailor-made partnerships between the Denver schools and Denver area businesses, raising even more support for the Denver schools initiatives in the future.

• The A to Z Fund was developed to provide funding support for individual school programs and projects, ensuring that every student has an equal opportunity to access the same types of activities and further enrich the learning experience of Denver schools students. The goal is to raise $100,000 by December 2006, with the first funding cycle beginning in February 2007.

• The foundation facilitated the requests of numerous donors, who wanted their donations to underwrite specific projects. Some of the projects were library improvement, health and safety education programs, new gymnasium scoreboards, and athletic equipment.

• The Lights On After School initiative was developed to advance the quality of after-school programs in support of the Denver schools students. The following accomplishments are from this program:

o $658,000 in grants was awarded to 87 elementary and middle schools to support their after-school programs that served approximately 8,500 Denver schools students.

o Over $260,00 ensured that 3,000 middle school students could participate in competitive after-school sports.

o A study, released in April 2006, showed that multiple-year participation in quality and diverse after-school programs in the Denver schools does result in positive student achievement and school attendance.

o Phillips Elementary School improved its reading test scores for third graders from 45 percent proficient or advanced in 2004 to 89 percent in 2005. The school attributes its successes to Lights On After School tutoring.

o Tom Roberts, a Morey Middle School student, finished first at the Denver-metro Math Counts competition in March 2006. Math Counts at Morey is funded by the Lights On After School initiative.

During the 2006-2007 school year, the foundation will continue to support the above initiatives, as well as the following:

• Teacher Induction Program — support new teachers during their first three years of service in the Denver schools, and

• Science Program — enhance the current science program by supporting new elementary school science curriculum and providing high quality materials for the new Science Resource Center.

Arizona Schools Benefit Form Science Foundation Grant

Wednesday, September 24th, 2008

In April 2007 the Science Foundation Arizona (SFAz) announced an investment of $3.2 million into a K-12 Student & Teacher Discovery Program that will benefit the Arizona Schools. The Arizona Schools grants are the third awarding of SFAz funds intended to create a top-notch science, engineering and medical core in Arizona. The foundation intends to create this by supporting and funding secondary and university level Arizona Schools.

Why Fund Science in Arizona Schools?

Science Foundation Arizona is a non-profit organization created in 2006 to “strengthen scientific, engineering and medical research programs and infrastructure in areas of greatest strategic value to Arizona’s competitiveness in the global economy.” In addition to benefits to economy, educators in Arizona Schools are aware of a growing achievement gap that most affects minorities and low-income students. That gap is greatest in areas of math and science.

Arizona Schools are an oxymoron in education. Education Week rated them last in the nation for per pupil spending in January of 2007. Yet it rated Arizona Schools 14th in the nation on academic standards, and 20th in education alignment. On the National Assessment of Education Progress (NAEP) the state came in 21st. Typically schools with lowest spending per pupil (like California) also rate poorly on other indicators of success; while the top spending states (like New Jersey) rank higher.

Superintendent of Arizona Schools, Tom Horne, wrote in his January 2007 district letter that although the national average is not a satisfactory goal, “… if our [Arizona] schools can bring our students to above the national average, even though we are last in resources, I believe we could be in the top 10 nationally if we raised our resources to the national average.” Clearly private funding from groups like SFAz is expected to help Arizona Schools reach that goal.

What Programs Will Benefit Arizona Schools?

Arizona Schools intend to use some of the funds for summer classes, teacher training and online courses. $225,000 will go to growing the Hands-on Optics Project run by the National Optical Astronomy Observatory in Tucson. This program lets elementary and middle school students in rural Arizona Schools learn about optics from scientists in surrounding communities.

The For Inspiration and Recognition of Science and Technology (FIRST) award gives $525,000 to the development of underprivileged K-12 students. Arizona Schools will participate in the First Robotics Competition and FIRST LEGO® League Programs with these funds.

As Arizona Schools try to address issues like English Language Learner program funding, and equity across racial and socio-economic lines, debates over allocation funds will continue to heat up. This is why a national trend of philanthropic and corporate sponsorship of public schools has become so popular.

Whether Superintendent Horne will get the additional state funding he seeks for Arizona Schools is still unknown. But it’s certain that the funds provided by SFAz will benefit the Arizona Schools in the 2007-2008 school year and beyond.

Are Faith-based Schools Divisive, Discriminatory and Dangerous?

Wednesday, September 24th, 2008

A generous funding arrangement both state and federal, implemented under the Howard government in Australia has seen a growth in independent faith based schools, a rise that is nothing short of revolutionary.

However it is not exemplary academic records that are luring parents to enrol, it is strong religious values and low fees that are the key draw cards. But are these schools beneficial to society as a whole or are they serving a small minority whilst eroding social cohesion, and are the rest of us paying for it?

The devout claim that parents have a right to have their children educated in a manner that integrates their faith and spiritual development. Whilst I respect the right and freedom of belief and the right and freedom of education it has never been the responsibility of publicly funded schools to instil religious faith and nor should it ever be. What you teach your children in your home is your business. Australia is a secular society and as such public funds should support secular education. Surely the responsibility of publicly funded schools is to do what they do best – improve teaching and learning for all students.

Because religious schools tend to draw students from singular ethnic communities almost entirely, they are in fact contributing to religious-racial segregation. This is not good preparation for life in a wider multi-cultural society. It enhances social exclusion, fragmentation and disrupts social cohesion.

In addition to funding from a secular-based taxation system for faith-based schools that fragment communities, the curriculum in these schools is also under scrutinised. What are students being taught and who are the educators employed to teach them?

Independent schools have been granted exemption from the state curriculum. Under Victorian law, it is not compulsory for private schools to teach evolution, though it is recommended and asks schools to teach it and explain the link between natural selection and evolution. However, as it is not compulsory for independent schools to teach this, it is widely accepted that creationism is taught in science classes.

The Accelerated Christian Education (or ACE) curriculum shows that in a primary school science class a statement such as: “God made many kinds of fish. He made them on day five.” is commonplace, with a comprehension test going along with the statement asking the children on which day God made fish.
Often evolution is not taught until senior high school years. It is obvious that the delay creates an illusion of choice of belief on behalf of the individual when in almost every instance children’s beliefs are long formed by this age. This has serious implications for further study. Increasing numbers of students are entering tertiary biology classes with creationist viewpoints that are irreconcilable.

One alternative to creationism and evolution that has also crept into the teachings at independent schools is Intelligent Design. This is also taught in science class. It boggles the mind. Intelligent Design is not based on facts and does not use any scientific reasoning. Intelligent Design is creationism relabelled. It has no place in a science classroom.

 

The scientific method is a set of techniques for the investigation and acquisition of new knowledge of the natural world. Therefore to qualify, a scientific a theory must be:

Consistent
Parsimonious
Useful (describes and explains observed phenomena, and can be used predictively)
Empirically testable and falsifiable
Based on multiple observations, often in the form of controlled, repeated experiments
Correctable and dynamic (modified in the light of observations that do not support it)
Progressive (refines previous theories)
Provisional or tentative (is open to experimental checking, and does not assert certainty)

Intelligent Design is at best anti-science and at worst blatant scientific fraud. Creationism in any form is just bad science. If religion and its theory of creationism has a place then surely it is in religious and philosophy classes, the home and in church, but never in a science class.

Moving on from unethical science education lets explore what is being taught in regards to sex education and homosexuality. What is being taught, and its broader effect on society, has been largely ignored. Government schools should be and are expected to deal with issues of safe sex, same-sex attraction, sexual harassment, homophobia and discrimination.

In direct conflict with government efforts to provide valuable and appropriate sex education to students, abstinence is instilled. Accompanied by a discriminatory assertion that sexual attraction should be expressed within the context of a monogamous, heterosexual marriage.

How is disparity in teaching even possible? Independent faith based schools are exempt from anti-discrimination laws. The exemption includes laws governing anti-discrimination pertaining to gender, religion and sexual orientation. So in addition to scientific fraud and an irresponsible sex education devoid of anything useful these schools can pay women less than men for doing the same teaching duties, expel homosexual students, sack teachers found to have different religious beliefs or those admitting to be homosexual themselves.

This at first glance appears undemocratic and on further investigation downright illegal. With increasing numbers of students being taught at these schools it will only take a generation for the equality gained by women, lesbians and homosexual men to unravel. This poses a serious threat to society as a whole.

Education must be a place where ideas are explored. Not where belief systems are indoctrinated. How will these students cope at university, in the job market and wider social environments where they will face, often for the first time, pluralism in religion, culture, ethnicity and sexual preference?

Our environment is at crisis point. Oil is running out. Drought is devastating agriculture. More and more people are starving in the world. The next few decades are crucial. We need critically thinking children who use evidence based reasoning to solve these problems, not faith based decisions. To suggest as some faith based schools do, that pollution is an effect of sin will do little to counteract it and its effect on our environment and health. What it will do is reinforce prejudice and intolerance.

Stephen O’Doherty, CEO Christian Schools Australia claims “Addressing inequality is about looking to the needs of the whole child and their social context. This commitment goes to the core mission of Christian schooling.”

This directly contradicts the anti-science teachings, discriminatory practices and irresponsible sex education. It is clear that the autonomy of children choosing their own beliefs and values is neither encouraged nor respected.

Independent faith based schools conflict with secular state education. A secular society and education offers children the opportunity to engage with people from diverse backgrounds where barriers to social inclusion are removed. An individual’s religious, cultural, and socio-economic circumstance does not limit their interaction. This has wider implications not just for the individual but also for society and the world as a whole.

Publications from The Paragon School of Sporting
http://www.paragonschool.com/publications.html

Take Your Best Shot  Book I — Take Your Best Shot (2nd edition)
Daniel Schindler’s first book, Take Your Best Shot, helps you get organized before and after you step into the shooter’s box. Regardless of skill level, your shot should be planned carefully before calling for the target. To finish a shot properly, it is vital that you start properly.

Using clear, plain language, this book answers your questions about equipment selection; chokes and loads; set-up in the box; strategies; shooting methods and managing your expectations. Written for the novice shooter, each shooting tip is a building block for the more advanced levels of shooting.

Good shooting starts in this very simple, easy-to-read book.

Readers have responded:

After our lesson Saturday I went home & made a page of notes – wondering as I wrote why you had not included these pearls of wisdom in Take Your Best Shot. Later that night I re-read your book & saw every one of them not only listed, but emphasized (maybe except for ‘cheek time’). It’s hard to overstate the added benefit of personal instruction & illustration compared to just reading the book.
Jim Bode

To The Target  Book II — To The Target
Dedicated to the Intermediate to Advanced Shooter
To The Target is, in a way, a map. Using plain language, it cuts through the mystery of shooting and shows you the shortest route to breaking one target after another — from the first field to the last.

Readers have responded:

To The Target is simply the finest literary work on the subject of sporting clays shooting available today. A virtual technical manual on the art and science of shooting sporting clays, it is absolutely essential reading for any serious competitor.
David Arnold, DO Davenport, Iowa

To the Target is full of valuable information directly pertaining to the shotgun sports. An essential part of any shooter’s library, I just wish it had been around when I started.
Andy Duffy, Holder of 8 National Titles

This is going to be the bible for all wingshooters. A stylish, instructional book, To The Target covers all the questions I have been asked by my clients. For the price of 1 round of clays, you will have your answers.
M. Palmer, Owner, Lone Pine Sporting Clays.

Beyond The Target  Audio CD — Beyond the Target:
An Introduction to Mental Training
Beyond The Target, an audio CD, is a perceptive, engaging introduction to the mental side of sporting clays performance. Produced and narrated by Dan Schindler, it provides the listener with a refined understanding of why shooters plateau, and why continued progress in the box and on the score sheet eventually becomes difficult. It offers a fresh, enlightening perspective on why our performance in the box is so dramatically affected by our thinking, beliefs, perceptions and concentration. The encouraging dialogue answers many of the key questions we’ve been asking ourselves before we step in, and after we step out of the shooting box. Delivering more than just suggestions and information, the author’s inspiring messages stay with the listener long after narration ends.

Dse Fuel Wins Nicole Her High School Science Competition!

Tuesday, September 23rd, 2008

Paul Simari

One of the biggest events at Union High School every year is the science competition. The smartest kids in town work all year designing something mechanical that can be used in daily life. The winner gets a $25,000 scholarship to the college of his or her choice, and the gymnasium is always filled to capacity the day of the event.

Nicole finished in the top five each of her first three years. But she was a senior now, and she wanted to win. She received trophies for finishing in the top five, which was nice, but it was that $25,000 she wanted. After all, she was just accepted to UCLA as a science major, and that scholarship money would help out Nicole and her family big-time.

There was just three months left till the competition, and although Nicole had been thinking about it all year, she just didn’t have any ideas yet. Last year, she designed an alarm clock that would jump off of the night-table and onto the ground when the alarm went off, so that you would be forced to actually get out of bed and chase it around the room instead of just being able to reach over and hit the snooze button. Chasing that clock around the room would be sure to wake someone up in the morning!

But that idea got Nicole third place, and she knew she would need something better to win that scholarship money this year. So she jumped on the Internet in search of some new ideas, and she came across a company called Diesel Secret Energy. She was amazed at what she was reading – a company that enabled you to make your own diesel fuel at home using boiler oil waste and cooking oil waste! This was exactly what Nicole needed – an idea that would not only help people save money on their own diesel gas, but also help the environment. The judges would love it!

Finally, the big day came. Nicole had received permission to enter the gymnasium the night before to set up her fuel making station. Everyone wondered what Nicole had in store when they saw her work station. When Nicole’s name was called, it was her time to shine! She explained to everyone how she had created a machine that could create diesel fuel using old vegetable oil. She demonstrated how easy the process was by mixing a few other ingredients in a large plastic garbage can, and also told about how this process helps prevent drain oil system waste and convert furnace oil waste.

The judges were blown away, and Nicole was awarded 1st prize, and her $25,000 scholarship!

High School Science Project Using Energy

Tuesday, September 23rd, 2008

Did you know that all foods we eat have some type of energy in them. That is why we eat them because our bodies need food to convert to energy and allow our muscles to move. Energy is heat for our bodies.

How can we see what type of energy a piece of food contains even though we are not eating it and digesting it? We will light a piece of food to show it has energy, Otherwise it would not burn and then use the energy from it burning to show it can heat water.

Get these materials for the science experiment:

A large coffee can

A smaller can like a soup can

A wooden skewer like used for barbeque

You will now want to punch holes around the side edges of the large coffee can. You can use an ice pick with a hammer on a wooden cutting board. Definitely have your parents do this part. The reason for doing this is so that you can release a small bit of oxygen.

The small can probably already has the top removed but if not go ahead and take the top off. Be careful as it will now have two sharp ends. You may want to ask your parents for help.

Punch two holes in the top of the small can on opposite sides. Again have your parents do this hole punching.

Put the wooden skewer through the holes so it evenly hangs from both sides.

Pour a small amount of water into the small can. (About 2/3 to ½ cup works well.) Only use room temperature water.

Use the thermometer to record the temperature.

Now have your parents use a lighter and light the marshmallow on fire.

Right away put the coffee can over the marshmallow and put the water filed soup can with wooden skewer on top of that. It should hang from the top of the coffee can over the marshmallow. It looks kind of like a camp fire as you are trying to heat the water in the soup can with the marshmallow.

Let the marshmallow burn until it goes out.

As soon as the flame goes out put the thermometer into the water and record the temperature.

Now you will do this with the peanut and piece of bread. (Note: the peanut may take a little while to light but do not give up. It will light because it has energy inside it.)

Make sure to record your temperature each time and use new room temperature water each time you do this.

What you have discovered is that each type of food we eat will burn because it has energy stored within it and that is what our body uses as fuel. Some foods have more energy inside them than others and that energy can be used to heat water just like it used the energy to keep our bodies warm.

What you are learning is that everything has energy which is measured in BTUs and for every BTU it should be able to raise four ounces of water 1 degree so when you see how many degrees the water temperature went up should show you how many BTUs of energy that piece of food contained.

High School Science Fair Project

Tuesday, September 23rd, 2008

High School Science Fair Project

Here is a great science fair project for high school that you will probably think is too immature for a high school student. However , this is exactly what you can do, especially for Chemistry class.

You are going to prepare a mixture which will have a chmical reaction and change the physical properties momentarily. This one will make you study the components for a while.

You will make a product I call liquid play dough because when you mix it and before you scoop it up it is liquid form, however, once in your hands and you start to play with it the composite will become very firm.

Here is your Objective: You want to compare and then contract two ingredients that you will mix. They are glue and liquid starch.

When you mix these two items together you need to watch visually and feel with touch for the changes that occur. Before I give you the exact recipe you need to make your hypothesis about what will happen to the goop when you play with in your hands, what happens when you leave it to rest. What happens if you don’t put this into a closed container.

Here is where your chemistry comes in to play.

Liquid starch or starch in general in made from glucose. Glucose is a sugar (a simple sugar).

Glue is made up mostly of proteins.

Think about the molecular structure of both of these substances.

When you mix the two of these together there is a link formed with these two substances and changes the physical properties of both substances creating a somewhat new substance.

Recipe for liquid play dough: liquid starch, household glue, a large plastic tub to mix the ingredients. I usually use an old cool whip type of container.

Put about 1/2 cup of glue in the plastic bowl. Now measure out 1/2 cup of the liquid starch. Look at both substances and make notes of what they look like, cloudy, clear, see through, the thickness of the liquid.

Pour the starch into the bowl with the glue and your hand to mix the two ingredients together so you can feel what happens as the two combine. As you mix you should get a somewhat slimy but yet firm product. If it is too runny add more glue.

If it is too firm add a little more starch.

Once it has formed a somewhat solid formation hold the new combination in your hand and put it under running water to wash off the excess starch and glue.

Squeeze the mixture between your fingers to see what happens when you continually play with it. Now let it rest and hold just in the palm of your hand. What happens to the mixture?

Roll it around again until it becomes firm and try to bounce it on the ground? What happened? Record your findings.

Try to stretch it and see how far and long you can stretch it before it tears. What happens? Record your findings.

Now put most of the new combo into a plastic baggie but leave a small piece out in the open air to dry out.

This may take more than a day but when it had dried out see if you can being the mixture back to life.

Now put another small piece in a baggie and put it into the freezer. What happened to it when you froze it? Try to thaw it and see if the mixture is the same.

What did this smell like, what color was it and what form did it turn into? Record all your findings.
