This term, Year 5 have been investigating Forces in Science, including water resistance. Recently, they incorporated their maths knowledge of shape (not to mention their artistic skills) to make 3-D spheres, cubes and cones from clay – we then dropped our clay shapes into water to investigate which shapes sank more quickly. In each group, the cube took the longest to reach the bottom and we were able to observe that this was because it created more water resistance. The more streamlined shapes travelled faster through the water. With this knowledge in hand, Y5 then made paper boats which we raced across a water tray to see if the same principle of streamlining applied.
