I weighed some containers of rocks on our kitchen scale.
Time to test how much weight the bridge holds. He continued disassembling and reassembling the bridge over and over again. Patrick showed Aiden how to assemble the bridge. He simply poked a hole in each cardboard tube.
To add more stability to the bridge, he added a piece of plastic from a broken clothes hanger to each side of the bridge. He cut notches into the tubes about the same width as the flat cardboard piece. Patrick used a serrated knife to cut the cardboard tube into 4 pieces. I challenged him to create a bridge from a thick cardboard tube and a flat piece of cardboard. My husband, Patrick, gets credit for designing this bridge. Our bridge is made of cardboard and plastic hangers. We will give you examples of projects for the theme on our blogs and in our Science at Home video series. Each month we will challenge you to complete a specific science activity with your children. We are calling the party Challenge and Discover. I’m excited to be hosting a new monthly science challenge link up with Science Sparks and The Imagination Tree.
