Year 5 Investigating water resistance

Date: 3rd Feb 2022 @ 11:33am

As part of our topic on forces, pupils were challenged to investigate the effect of water resistance on an object.  We molded playdough into different shapes and dropped them into water to see how fast they would sink. We discovered that, thin shapes and ball shapes sank faster than large flat shapes. This is because the larger shapes created more water resistance! Water resistance is the force of the water pushing back against the force of gravity - which is trying to make the object sink.
