Full of focus, junior Timothy McCullough and senior Chad Goodman, re-adjust the net for the projectile on their trebuchet Friday. In John Krehbiel’s Physics Honors class, students were given about a month to design and construct their projects. “This assignment was a really fun way to learn about projectile motion because I really like hands on work and that’s exactly what this was,” McCullough said. The goal of the experiment was to present a lesson in projectile motion in a kinesthetic way that would not only teach students, but entertain them as well.
