Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

After a brief lecture on levers, torque, projectiles, and the five-step engineering design cycle, young physical science learners or engineers build catapults out of craft sticks. This is an open-ended exploration of what works and what...

Students construct a hovercraft following specific procedures. In this technology lesson, students explain the physics principles behind hovercraft. They compare and contrast this machine with the aircraft.

Young scholars compare and contrast where friction occurs in robots and bicycles. For this science lesson, students label the diagram of bicycle and robots. They investigate how friction affects their different parts.

Students incorporate knowledge box into their classroom activities. In this technology integration lesson, students fill out a graphic organizer using Glossopedia to analyze a new subject.
