We had to create a tower with the materials you see (and only had a certain amount of each) that could hole one of those science books you see on the back counter. They were heavy! If our tower could hold the book, you succeeded, but if it did not, your tower failed.
You notice that the "Pinwheel Princesses" won with 247- that was the fourth grade teacher from CCES! We were so excited! We had to use juice carton, paper, straws, and popsicle sticks to create a windmill that could pick up the most weights. The picture below was our final product.
