Summer Learning Journey | Building a super with Nanogirl

I have created three columns to test out which ones can hold up after given an object to put on. 

First I watched a video to test out which columns are strong. The shapes were 3D triangle, cylinder, and a flat piece of paper that is being faced side ways with a folded corner. 

Next I created my own columns, and tested out with little shampoo container. The results were: flat paper fell, but the cylinder an the 3D triangle didn't fall. 

I found this activity challenging because there weren't cardboard in my home and I tried to find something that was hard.
