STEM Day - chain reactions

On our STEM Day about cause and effect we made chain reaction machines.  In the morning the children worked in small groups to make table top ones.
In the afternoon, we all worked together to create a giant cause and effect chain reaction that went from one end of the school to the other!
Our thanks to Diana Ross for encouraging us to 'get in the middle of a chain reaction' and whose music we have used in the video.
