We learned to put different electrical devices into our circuits. Then we drew these in our books using proper circuit symbols.
Later we tested different materials to see if they were conductors or insulators, We did these by putting them into our circuits and observing whether the bulb stayed on or went out.
We had a lot of fun learning about and investigating sound. Our investigations showed us that sound travels through vibrations, which are very fast backwards and forwards movements.
We had fun talking and listening through string telephones. We also found out why they worked.
We studied the pitch of different instruments and even made one of our own!
We investigated using sound maps how the distance we stood away from the sound source affected its loudness when we heard it.
We've been learning about the different types of teeth we have and what we use them for. In our table groups we made a mouth out of plasticine to show this. Can you tell which teeth are incisors, canines and molars?
