Discovery Science Step 1: Energy and Forces – Sound

Strange Sounds

Objective: understand and explore how different sounds may be made by making a variety of of materials vibrate

Skills: Experimenting, Observing

The children undertook 3 experiments investigating sounds in its different formats. The children could “see” sound as they struck the saucepan with implements. The children dicovered that the distance of the saucepan from the rice effected the intensity of the vibrations. They also discovered that the metal spoon created greater vibrations. The children could “hear” vibrations through the balloon and the children created sounds of different pitch by cutting straps in different lengths and blowing through them. The children also learned about how sound travels and how we hear.
