Make observations to construct an evidence-based account that objects in darkness can be seen only when illuminated. (Cause and Effect) Clarification Statement: Examples of observations could include those made in a completely dark room, a pinhole box, and a video of a cave explorer with a flashlight.
Give your students an introduction to sound waves in 8th grade with OpenSciEd! This unit meets NGSS standards MS-PS4-1 & 2 so you can trust the quality of the lesson plans.
