Course overview


Weekly Learning Plan Trailer


Physical or Chemical?

Students will learn about what a chemical change is by identifying the evidence of a chemical change and what chemical, physical properties are.


A Closer Look into Matter

Students will learn what’s happening at a microscopic level during a chemical change, learning about atoms and molecules.


Chemical Reactions

Students will try their own chemical reaction and observe color change as the evidence with a penny.
