Effects of Heat & Light on Plants & Animals

This lesson plan outlines an activity to teach 4th grade students about the harmful effects of excessive heat and light on plants and animals. Students will be split into two groups. One group will observe the effects of different levels of heat on two sets of plants using an electric blower. The other group will do the same with two earthworms. After their observations, students will answer questions about how the heat affected the plants and earthworms and whether the effects were harmful. The lesson aims to help students understand the content standard of how light, heat, and sound travel and describe ways to protect oneself from their excessive exposure.
