Our next topic, Sound, started this week. We began by playing a game called Identify the Sound. This was great fun with some very interesting noises.
Following that, the class were asked to predict which areas in school would be the quietest and loudest. Then, off we went.
Year 4 were asked to complete their sound walk in total silence. The only sound was the beat of a drum to give them the next instruction. This was a great success!
The next part of our lesson was to find out how sounds are made and how they travel.
Using instruments and varying levels of noise, we learnt that sound is created when something vibrates and sends waves of energy (vibration) into our ears. The vibrations travel through the air particles to the ear.
- “The stronger the vibrations, the louder the sound.”
- “Sounds are fainter the further you get from the sound source.”
- “Sound changes depending on how fast or slow an object vibrates to make sound waves.”
Having discovered how sound travels through air, our next challenge will be to find out whether it can travel through water and solids.
