We have been learning about different states of matter in Science. This lesson we looked at gases, we took part in 4 mini experiments where we could see that gases were present. We blew feathers,  we crushed bottles it the lid of and on, we smelt objects, and we squeezed sponges. We learnt that gases can move freely and in different ways within it's container. So it was harder to squish the closed bottle because the air was trapped in a smaller container, but easier elsewhere because the room is a large container.
