This is an easy, fun experiment to find out how strong different shapes are. Shape 1 sheet of paper into different shapes and see how much they can hold. We made a triangle, square, and cylinder.
A hypothesis is a special word that scientists use for “an idea that you can test,” it is also a kind of prediction. Make a hypothesis of which shape will hold a book best. Do you think a circle will be stronger than a square?
Test your hypothesis out! Does your shape hold more than one book?
Can you think of other shapes or structures that might be stronger? Share your ideas below!
