Sunday, July 10, 2016 Objective: YWBAT describe characteristics of elements, mixtures, and compounds. Drill: Describe the differences between chemical and physical changes. Give an example for each. Homework Test Wednesday

Chemical changes One or more substances are changed into entirely new substances with NEW properties Cannot be reversed using physical means Iron and oxygen forming rust

Physical Change A change that affects one or more physical propeties (senses) of a substance Many physical changes are easy to undo Changes of state are physical changes
