On Friday, the Grade 3 classrooms turned into a physics lab to investigate friction, gravity, and magnetic and electrostatic forces. We used a catapult to measure the impact of forces. Our forces were measured in Newtons. Did you know that Newton discovered gravity after an apple fell on his head? We ran experiments with magnets to see if they can defy gravity. Our magnets did some fun tricks; they were attracting, repelling, and even spinning without actually touching. We tested the effectiveness of seat belts by looking at momentum.
This experiment validated that we should always wear seat belts for safety. Last, we became magicians as we investigated electrostatic force. We turned ordinary straws into magic wands and we made styrofoam dance and jump. What an amazing workshop hosted by Scientists in the Schools.
