Clean air

This term’s topic is ‘clean air’ – Entry level Science

We talked a lot about the key words.
We weighed balloons full of air to see that they weigh a little bit but really not very much.
We swung our arms around to feel air resistance and prove there is something around us that we cannot see.
and we decided that the atmosphere is a circle of oxygen around the planet. Close, and we’ll make improvements next week!
