Lessons
Inclined Plane
In this lesson, students will assemble an inclined plane and learn how it’s used to multiply force. Then, students will design and engineer a custom inclined plane to solve a challenge.
Wedge
In this lesson, students will assemble a wedge and learn how to calculate its mechanical advantage. Then, students will develop a custom design that includes a wedge.
Lever
In this lesson, students will assemble three different types of levers and learn how to calculate the mechanical advantage of each. Then, students will work as a team to design and engineer a custom catapult that includes a lever.
Wheel & Axle
In this lesson, students will assemble a wheel and axle and learn how it is used to increase speed or create mechanical advantage. Then, students will work as a team to create a design that includes a wheel and axle.
Screw
In this lesson, students will assemble a screw and learn how to calculate its mechanical advantage. Then, students will work as a team to design and engineer a custom design that includes a screw.
Pulley
In this lesson, students will explore how fixed and movable pulleys can be used to make work easier. Then, students will design and engineer a custom pulley system to solve a challenge.
Unit Assessment
In this assessment, students will answer a series of questions to demonstrate an understanding of the core ideas and concepts that were covered throughout this unit.
