Class 3 Science Day
Today Class 3 investigated Newton’s Third Law, the theory that for every action there is a reaction. They took an empty carton and placed small holes in each of the bottom corners then used masking tape to seal these again. Using a funnel, they filled the carton with water and removed one of the pieces of masking tape. The water jetted out one way and the carton spun the other. It wasn’t as spectacular as they had hoped but they enjoyed getting wet in the name of science!
Class 3 proved that water molecules are attracted to each other causing surface tension. They used pipettes to drop water on the surface of a coin. When washing up liquid was added to the water the surface tension was dramatically reduced.
