Staff and the Science Ambassadors from Eastbury came to visit year 4. They showed us experiments to do with fuel and we also got to have a go. Firstly, we used lemon juice and baking soda to blow up balloons, we learnt that the fuel used to help with this was carbon dioxide.
Secondly, we got to experiment with Rocket Balloons, we used different sized string and straws to be able to see which materials would let the balloons move fast and slow.
Year 4 thought it was great fun! and look forward to seeing them again.
