Easy Kid Engineering: Let's Cardboard Build bridges!
(Does folding paper make it stronger?)
We cut out several cardboard and paper rectangles. Then, we folded some pieces different ways to test out their strength.
Which one do you think will hold the most weight?
Then, we grabbed some things from around our home to create the bridges and test their strenghts.
And then we got building!
And then we built some more!
We found that creating folds in one direction helped to make our paper and cardboard stiffer and stronger. We also found that folding them another way actually made the cardboard less sturdy!
Then we just went to town and tried to see just how strong our folded cardboard bridge actually was. So, we stacked as many things as we could onto our strongest bridge. Wow. It's pretty amazing how much weight it could hold.
