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.
Sound is all around us. Everything we hear in our day-to-day lives has a distinctive sound, from the jingling of keys to the tapping of footsteps in a hallway. Sound is created when objects vibrate. These vibrations cause the air around them to vibrate, sending sound waves in various directions. Some objects tend to vibrate at a specific rate. This is known as their resonant frequency. In this activity, students will explore the vibrating nature of sound and how it travels from molecule to molecule.
