Off they go — launching rockets is fun. The lesson plan contains templates to build paper rockets that can be launched from a PVC pipe launcher. Individuals or groups build the rockets and determine the shapes for their fins. Included...

Fourth graders examine the simple machine known as a plane. They build their own pyramid and identify the role of screws. They participate in a hands-on activity in which they determine the angle in which to make it easier to pull.

Students role-play as engineers designing wedge tools. They devise methods for shaping quarry rocks into pyramid blocks. Following a teacher demonstration, they use materials such as soap, clay, and foam for blocks and wood, plastic,...

Students explore the building of a pyramid and how pulleys were used to change the direction of applied force. They demonstrate the mechanical advantage of using a pulley and apply it to modern engineering.
