Exploding Gummy Bear
Reaction in a bag (depending on the age, break the reaction down)
The Bounciest ball
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?
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.
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
