We spent more time today finding out about sound.
It was so interesting.
Today we found out about vibrations and sound waves.
Teacher had a tuning fork.
We were really surprised to see that it doesn't make much sound in air, but it makes such a clear note when we put it against our ears.
We know that sounds can travel through the air. These sounds sound quite different when they travel through solids (like string).
We were right!
