On Tuesday the Grade 3 students investigated the impact of friction, gravity and magnetic force through a FORCE, OF COURSE workshop presented by Scientists in the Schools. We learned about natural forces like the eruptions of volcanoes and how the vortex of a tornado can uproot trees. We used catapults to measure the impact of forces on a ball. Do you know how a force is measured? Forces are measured in Newtons, named after Sir Isaac Newton after an apple fell on his head. We designed a marble roller coaster and experimented with magnets to see if they can defy gravity.
