In Science Club, Year 2 made ‘balloon rockets’. We
talked about the science involved. As the air rushes out of the balloon, it
creates a forward motion called THRUST. Thrust is a pushing force created by
energy. In the balloon experiment, our thrust comes from the energy of the
balloon forcing the air out. Different sizes and shapes of balloon will create
more or less thrust. We tried using standard balloons and longer balloons to
see is this had an effect.
