Explosive Science
In this activity, students will use household materials to investigate and explore how the release of carbon dioxide gas from a chemical reaction can cause a small-scale explosion. Students then will experiment with variables to determine which factors launch a film canister the highest.
Fun With Optics
In this activity, students will perform several experiments, using simple materials to explore the properties of reflection and refraction and how they work in telescopes.
