Yesterday in Science, we have learnt more about how sounds travel. To begin the lesson, we recapped what a sound it and how sounds are made by objects vibrating. We then figured out that sounds can be louder and quitter depending on how big the vibration is by getting some children to leave the room and make different sounds. We also found out that sound can travel through objects and some materials block sound more than others.
Our experiment was to make our own string telephone in order to find out how sound can travel along an object that is vibrating and into the ear.
We worked in tables to make our sting telephone, then wrote down our equipment, hypothesis, observations and conclusion on large paper.
