Physical Science - Unit E (Grade K)




Matter can be described by its observable physical properties, the materials it is made of, and its uses. There are three different states of matter: solid, liquid, and gas. Matter can be changed by folding, bending, tearing, or mixing it. Light can pass through some forms of matter, but not others.
