Light and sound are everywhere, but hard to define. These age-appropirate activities will provide your students with a solid basis for exploring these concepts with confidence. Experiments with laser beams and hands-on models will delight students as they learn about light. Practical activities with music, handmade telephones, and model ears will instill a love for learning science in students while teaching the basics of sound. Activities are curriculum based, and also include highly motivational experiences - like playing tag using echolocation, just like bats.
