Format
1. This program begins with discussion of matter and demos of physical and chemical changes
2. Criteria is established for each kind of change
3. Polymers are introduced and students will make GAK
4. Students will conduct their own lab and determine what kinds of changes are occurring
5. Students will make observations and predictions of chemicals and reactions.
Objectives
1. Students will differentiate between physical and chemical changes,
2. Students will become familiar with the physical characteristics of a polymer,
3. Students will relate both physical and chemical changes to the Law of Conservation of Matter, and
4. Students will use scientific inquiry to design their own experiments.

3.PS1.B1 Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
5.PS1.B2 Conduct an investigation to determine whether the combining of two or more substances results in new substances.

5.P1U1.1 Analyze and interpret data to explain that matter of any type can be subdivided into particles too small to see and, in a closed system, if properties change or chemical reactions occur, the amount of matter stays the same.
5.P1U1.2 Plan and carry out investigations to demonstrate that some substances combine to form new substances with different properties and others can be mixed without taking on new properties.
8.P1U1.1 Develop and use a model to demonstrate that atoms and molecules can be combined or rearranged in chemical reactions to form new compounds with the total number of each type of atom conserved.
