As you might know, the parabola is a section of a cone. While discussing geometric shapes we started talking about parabolic curves. We made our own by graphing 1″ increments up and down a square piece of paper and then connecting them side to side, all the way around the page. It was tricky to keep track of which line went to which side!
We are planning to do this with string to make our very own design. We were surprised to see a curve develop out of perfectly straight lines!
