Evidence of Chemical and Physical Change
Standard 1: Students will understand the nature of changes in matter.
Objective 2: PDF - Observe and evaluate evidence of chemical and physical change
- Identify observable evidence of a physical change (e.g., change in shape, size, phase).
- Identify observable evidence of a chemical change (e.g., color change, heat or light given off, change in odor, gas given off).
- Observe and describe chemical reactions involving atmospheric oxygen (e.g., rust, fire, respiration, photosynthesis).
- Investigate the effects of chemical change on physical properties of substances (e.g., cooking a raw egg, iron rusting, polymerization of a resin).

- Physical and Chemical Reactions
- Set of experiments that show the difference between a physical reaction and a chemical reaction and the 4 ways in which a reaction can be sped up; (concentration, surface area, temperature, & catalysts).

- Chemical and Physical Changes
- Students make observations of various phenomena to try and determine if a physical or chemical change has occurred. During this process, students also make conclusions about evidences of a chemical change occurring.
