Previous6th class did the rain in a jar experiment. The shaving cream in the jar represents the cloud. Blue food colouring is dropped into cloud eventually becoming so heavy that it can no longer hold the water. It rains down into the jar.They also took part in a STEM activity with MakerMeet. Building a paper tower that can hold a 100g weight.
Next6th class did the experiment of inflating a balloon using water, lemon juice and baking soda. The reaction between the lemon juice and the baking soda solution is one that creates a great deal of carbon dioxide gas. As the lemon juice and baking soda react, more and more of the gas is given off. As the gas accumulates, the balloon becomes bigger and bigger.
