Balloon Race Cars Kit


Race to the finish with balloon-powered race cars and Newton’s laws of motion. Design teams build and test a prototype car, then explore how changes to the wheels, body, and balloon alter the performance. To successfully compete in the class challenge for maximum speed or distance, teams must overcome obstacles such as friction and car stability. Extend the lesson to cover propulsion, force dia- grams, aerodynamics, and energy conservation. This activity is an excellent way to incorporate math and engineering skills into your science lesson. Materials sup- port 15 design teams. Includes instructions. /!\ WARNING: CHOKING HAZARD— Children under 8 yrs. can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.

750046 Egg Drop Kit Egg Drop Kit


Protect the falling egg with engineering, geometry, and physics! Design teams create a device from everyday materials to absorb force and protect an egg from an inital 1-meter drop. After investigating the strength of 3-D geometric shapes, teams incorporate this knowledge to reduce the energy of impact. The final models compete to achieve the highest drop distance resulting in an intact egg. Explore energy conservation, collision forces, momentum, and Newton’s laws. Materials support 15 design teams. Includes instructions; eggs are needed but not supplied.

750042 Mousetrap Cars Kit (above); in use (right)


750044 Structures Kit Structures Kit


Explore the strength, resilience, and function of geometric shapes, angles, and curves as structural components. Design teams choose 1 of 2 load-bearing struc- tural engineering challenges: bridges (horizontal) or towers (vertical). To be suc- cessful, teams must combine their knowledge of geometric shapes, load-bearing, forces, and vectors to create the structure that holds the most weight. Activity incorporates Common Core math applications and engineering standards. Materi- als support 15 design teams (1 prototype and 1 rebuild). Includes instructions; weights to test strength are needed but not supplied.


750044 Per kit 100% satisfaction guaranteed Mousetrap Cars Kit


Speed to excitement with a car powered by the energy of 1 mousetrap. Prototypes use the clas- sic setup of string connected to the lever arm to move the axles. To achieve maximum speed or distance, design teams alter variables that affect


the vehicle’s performance: friction, mechanical advantage, and mass. This hands- on activity helps students learn the concepts behind levers, machines, and poten- tial and kinetic energy, then apply this knowledge to the engineering challenge. Materials support 10 design teams of 2 to 3 students. Includes instructions.
