In attempt to remember all the "good" lessons that I observe my teacher teaching... I will note her science lesson used today. She was teaching about how sound travels in vibrations. In order to do so, she had a small bowl of water and a small, medium, and large tuning forks, like these.
With the students sitting in a circle so all could see, she hit the tuning fork on the ground and immersed it in the water. Immediately, the water splashed up and hit some of the students! The vibrations caused the water to splash out of the bowl. They were fascinated. It was a great way to demonstrate how sound travels and get students excited by science.
The lower-pitched tuning forks provide longer, lower vibrations, resulting in a smaller splash than the higher pitched tuning forks. She also varied the level of vibrations by changing the amount of force used to strike the tuning fork. For a formative assessment, she asked students how sound travels. Each student understood that sound travels through vibrations and can travel through all types of matter!
Definitely want to remember this lesson. :)
Love the visual she created. Keeping kids engaged with the "magic" of science!
