Gizmo of the Week: Sled Wars

Between last week’s “bomb cyclone” blizzard and the freezing temperatures across much of the United States, it’s a great time to go sledding! The Sled Wars Gizmo introduces students to energy changes that occur as a Yeti in a sled travels down a hill and hurtles into a row of snowmen at the bottom. Students can also experiment with two sleds colliding into one another. In their experiments, students see how potential energy is converted to kinetic energy as the sled moves downhill, and how speed, energy, and momentum change in a collision. Happy sledding!
