On the eighth of June me Tylar and Lucy investigated sound with four glasses of water. The glass with the most water makes a lower sound because it vibrates slower because there is more water in it than the ones that make higher sounds, the one with the least amount of water makes a higher sound because it vibrates faster.
Great video Zak, Lucy and Tylar and well done Zak for being confident and taking the lead. Your experimenting was very clear and organised. You have written a good explanation Zak.
