750036 Roller Coasters Kit (in use) Roller Coasters Kit
Unleash Newton’s laws as thrill-seeking design teams explore roller coaster physics for a hands-on experience in energy transformation. Teams evaluate the descent of a small sphere (wood, glass, or steel) through loops, turns, and hills on a foam insulation track, then extend that knowledge to engineer the best structure for the class challenges of highest hill, largest loop, or maximum velocity. Use this engaging engineering activity to explain the forces behind the fun—potential and kinetic energy, energy conservation, acceleration, and laws of motion. Materials support 10 design teams. Includes instructions.

750034 Motors Kit (in use)
Motors Kit Get charged up about motors and electrical engineering. Design teams assemble a simple motor from a D-cell battery, wire, and a magnet. After experimenting with wire type (gauge and metal), number of wire coils, and magnets (quantity and type), designers enter their best models in the fastest motor challenge. Teach electricity, circuits, and motors with this engaging, hands-on engineering activity. Materials support 10 design teams. Instructions included.

750028 Paint Stirrer Catapult Kit
Paint Stirrer Catapult Kit Launch projectiles and learn about levers with a desktop catapult built from paint stir sticks. Modify the catapult and conduct trials to explore how the fulcrum size and position, plank length, effort force, and load mass all affect trajectory and dis- tance. Design teams use this data to update, retest, and troubleshoot the prototype to perfect the catapult. For assessment, the best design competes in a class chal- lenge for height, distance, and accuracy. Students are sure to better understand the principles behind levers after this enjoyable activity. Supports 15 design teams of 2 to 3 students. Includes instructions and diagrams.

Build It Write Kit Reinforce the importance of tech- nical writing and following direc- tions with an engaging hands-on activity that stimulates creativity and higher order thinking skills. Design teams create a structure from colorful craft
items, then
explain how to build an exact replica through written instructions (no pictures, diagrams, or symbols). To be successful, teams must show attention to detail and effective written communication. Expand this lesson to cover science writing or engineering topics such as reproducibility and repeatability. Excellent activity to help meet Common Core writing standards in a science classroom. Materials sup- port 16 pairs of students. Includes instructions.
