In this unit, you will investigate the physical world from a chemical viewpoint. You will compare the physical and chemical properties of substances, create models of molecules, and demonstrate how different factors, such as thermal energy, affect substances. You will have an opportunity to design a procedure to separate a mixture and discuss with your classmates how thermal energy impacts a substance in different phases.
