Today we had a fun science day.
The children learnt that sounds are made when objects or materials vibrate. They looked at how changing the vibrations could make sounds that were louder or softer. They also looked at how changing the vibrations can change the pitch of a sound, making it higher or lower. The vibrations can travel from a sound source better through some materials and so the children decided to investigate this further.
The children had 4 different activities that they rotated around:
1. Investigating how to change the pitch, when twanging a ruler.
2. Investigating how to make different sounds louder, quieter, higher and lower.
3. Investigating which material muffles sound the best.
4. Using an interactive game, answering lots of questions about sound.
Investigating which chime bar has the highest/lowest pitch
Ruler experiment
Was that fun, it looks like it!
