Lesson Plan

Heat, Light, and Sound

Students record the temperature of different surfaces.


In the classroom, students review the properties of waves. On the field trip, students investigate what objects absorb and retain the most heat, and then use sound waves to find local birds. They observe how lenses change light waves, discovering how common objects use lenses to bend light to meet our needs, and they investigate how sunscreen blocks UV waves. Back in the classroom, students discuss when our use of heat, light, or sound waves becomes overuse.
