Chain Reactions! Design and build amazing moving machines and teach LEGO® bricks new tricks! Guided by imagination, students will discover endless possibilities as they explore physics and engineering concepts such as velocity, projectiles, trajectories, force, and motion. Working in pairs, they will experiment each day with new ways to combine LEGO pieces to trigger chain reactions. On the final day, students will apply what they’ve learned by designing and building their own Rube Goldberg machine that sets off an unforgettable chain of events.
