Don’t just drop eggs from heights to see what happens; use math and science to find out! The Bungee Egg Challenge program is an excellent simulation of the design of an egg-drop project. The relevant physics concepts of damping, forces, elasticity, and kinetic and potential energies are described, and tools for interactive exploration of these concepts are provided in the program. After exploring these tools, the students can use their acquired knowledge in the virtual “Egg Drop Lab” where the goal is to avoid a noisy splat! When they have a design that works in the virtual lab, they can build their design and test it to verify that it works. The drop test will challenge their knowledge and lab skills. Lesson and lab plans are included on the CD.

No playmate needed for this seesaw!

Featuring just one axle and two wheels, The Seesaw has half the friction and rotational inertia acting against it as compared to other mousetrap vehicles. After the mousetrap releases, the racer’s chassis seesaws briefly before balancing out for a clean run.

All parts come precut and predrilled for quick and easy assembly. The Seesaw travels 15-20 meters on average. Requires white glue and needle-nose pliers, sold separately.

Designed for all speed contests and “king of the hill” climbing challenges, The TorqueMaster is engineered to provide as much as 100 percent more torque and extend the pulling force up to 50 percent longer than conventional systems! The TorqueMaster’s pulley system maximizes the winding of the mousetrap’s spring to 360 degrees, causing it to explode off the starting line. Requires a drill, scroll or hand saw, glue, and needle-nose pliers, sold separately.

Understanding Flight bypasses common distortions, misconceptions, and half-truths and gives your students a brain- and gut-level understanding of what gets a plane up in the sky and keeps it there. Students will learn the whys and hows of wing shape, stability and control, propulsion systems, flight testing, high-speed flight, and more. This second edition includes helicopter-flight fundamentals and aircraft structures.

The principles of flight are often parroted but widely misunderstood. Now your students can be among those who truly get it.

Great as a first- or second-time model! The Viking can be built with three, four, or five die-cut fiber fins – your choice. Easy-to-build, no painting required, and can fly to 1,000 feet and higher. Includes self-adhesive decals.


When you hear the plaintive cry, “Why do I have to learn this stuff – I’ll never use it anyway,” you can point the whiner to this poster that features dozens of reasons for learning geometry. From managing money to building a doghouse to tracking the path of a storm, one of the reasons is sure to convince your students of the practical applications of this fundamental mathematical science.
