Investigate sound waves with acoustic mirrors. Using audio software, groups make recordings of musical instruments, both with and without acoustic mirrors. They compare the recordings to see the effect of acoustic mirrors on sound...

Students investigate the law of reflection by using mirrors. In this physics lesson, students operate a robot using IR controllers. They explain the path of light as it reflects through a surface.

Here's the perfect lesson for those who think the world needs faster pumps. Building on the previous activity, scholars work to make the pumps function faster in transferring water between containers. They try adding an additional solar...
