Earth and Space:
The children finished their topic on Earth and Space by carrying out an investigation into rockets. We went through the method for getting our rockets to launch. We discussed how baking soda and vinegar react together to form carbon dioxide, which creates fizzing as it escapes the solution. This gas will rush up – if it has nowhere to escape then the pressure builds. Eventually the pressure builds so much that an explosion occurs!
We planned an investigation together and the children got into groups. Each group put a different amount of baking soda into their rocket to see if this would affect how high it would travel. We launched our rockets outside which was great fun. However, the most fun was had when a rocket exploded all over Mr Woods covering him in vinegar and baking powder!
