During the associated lesson, students have learned about Newton's three laws of motion and free-body diagrams and have identified the forces of thrust, drag and gravity. As students begin to understand the physics behind thrust, drag and gravity and how these relate these to Newton's three laws of motion, groups assemble and launch the rockets that they designed in the associated lesson. The height of the rockets, after constructed and launched, are measured and compared to the theoretical values calculated during the rocket lesson. Effective teamwork and attention to detail is key for successful launches.

Students apply their mathematics and team building skills to explore the concept of rocketry. They learn about design issues faced by aerospace engineers when trying to launch rocketships or satellites in order to land them safely in the ocean, for example. Students learn the value of designing within constraints while brainstorming a rocketry system using provided materials and a specified project budget. Throughout the design process, teamwork is emphasized since the most successful launches occur when groups work effectively to generate creative ideas and solutions to the rocket challenge.

Students learn about how biomedical engineers create assistive devices for persons with fine motor skill disabilities. They learn about types of forces, balanced and unbalanced forces, and the relationship between form and function, as well as the structure of the hand. They do this by designing, building and testing their own hand "gripper" prototypes that are able to grasp and lift a 200 ml cup of sand.

Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.

Students are introduced to the concepts of torque, power, friction and gear ratios. Teams modify two robotic LEGO® MINDSTORMS® vehicles by changing their gear ratios, wheel sizes, weight and engine power, while staying within a limit of points to spend on modifications. The robots face each other on a track with a string attaching one to the other. The winning robot, the one with the best adjustments, pulls the other across the line.
