Exhibit Walkthrough
Live Activities:

The Bounciest ball
Questions:
What does it mean when something is considered “synthetic”, where do synthetic materials come from?
How can you tell a chemical reaction has occurred?
What variables can impact the rate of a chemical reaction?
Objectives
Content Goals:
At the conclusion of this program, students should be able to:
Understand that physical changes can be reversed, while chemical changes are permanent.
Understand that atoms and molecules have particular structures and form bonds.
Identify synthetic, non-natural, materials are made from natural ones.
Performance Goals:
During this program students will:
Recognize that the total number of atoms does not change in a chemical reaction
Communicate what type of change has taken place, chemical or physical
Experiment with reactants to create the bounciest ball

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-3: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
MS-PS1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved
