In Unit 3, Chemical Reactions and the Laws of Conservation of Mass and Energy, we will observe how all of these different forms of matter that we have been studying form through the process of chemical reactions. It is always amazing to me that with just the handful of elements found on the Periodic Table, we can make all of the different types of matter found in the universe. (I like to compare it to the way that twenty-six letters of the alphabet can be formed into a dictionary of words.) Along the way we will learn that matter and energy can never be created or destroyed during these chemical reactions. We will review chemical formulas and practice balancing simple chemical reactions to show support of the law of conservation of matter.
The essential learning targets for this unit are as follows:
- I can explain/define a chemical reaction and cite evidence to determine if a chemical reaction has occurred.
- I can identify the substances in a chemical equation as reactants or products.
- I can define the law of conservation of mass and determine if a chemical equation supports the law or not.
- I can predict, then design and test an experiment that will either absorb or release thermal energy through a chemical reaction.
