How is sound made?

Year 4 have just started a new topic - Sound. They began with an investigation into how sound is made. They used: a violin and observed the movements of the strings, a cymbal and felt the movements, a drum and looked at the vibration of coffee granules and felt their vocal chords vibrating when they talked.

Volcanoes

As part of their topic 'Active Earth', Year 4 made volcanoes by creating a reaction between vinegar and bicarbonate of soda. They added red food colouring to make it look like real lava!

States of Matter

Year 4 have been learning all about states of matter and discussed solids, liquids and gases. They learnt about the structure of each and also learnt that materials can change from one state to another by cooling or heating. In solids, the particles are tightly packed together. In liquids, the particles are less tightly packed and able to move. In gases, the particles have lots of room and are free to move around. They went outside and used their own bodies to represent each of the three states of matter. See if you can guess which one is which!

Forces

Year 5 have been learning about forces and linked this with their topic on Space. They investigated water resistance, making predictions about which shape would fall to the bottom of a glass of water first. They also looked at air resistance, creating parachutes out of different materials and making conclusions about which material created the most air resistance based on the amount of time it took to fall to the ground.
