Launching Technology Lesson

In their technology classes, seventh-grade students at P.J. Gelinas Junior High School are learning about a variety of physics concepts this year, including centrifugal force, gravity, inertia and momentum.

To kick off their studies, the students experienced these concepts in action as their teachers used a giant catapult, called a trebuchet, to launch pumpkins high into the air. During the daylong event, the entire studentbody had the chance to see how the trebuchet operates and learned about the concepts in motion.

Throughout November, the seventh-graders will build miniature trebuchets and test their launching capabilities using small pieces of clay.
