Students will explore through hands-on investigation concepts such as gearing up/down and increasing speed/force as they build crank fans, egg beaters and more. Includes building instructions for 6 different models with real-life photo and key facts. Complete set includes building materials in a sturdy divided case, teaching resource CD (with teaching notes,… More »

6 years & up. This is not your ordinary addition to the marble run family! Put the laws of motion to the test with this Mega Stunt set. The ingenious pieces interlock in endless configurations, while double-exit cubes keep you guessing on which way the marbles will go! Set includes: 108 cubes, 2 cascade stilts, 2 coaster tubes, 1 marble vortex, 1 pivot trampoline, 2 universal connectors, 30 steel marbles, and instructions.

8 years & up. Experience the power of gravity with the Gravitrax Starter Set! Build your own action-packed track system to send your marbles racing while learning about gravity, magnetism, and kinetics. With over 100 pieces and 18 different construction elements, discover how the laws of physics affect the track your marble takes with curves, crosses, freefalls, and even a cannon. Experiment using different heights and angles to control the speed of the ball. Build your track using the construction… More »

5 years & up. Develop a knack to stack! No glue or connectors required -- simply stack wood planks to create buildings, monuments, and geometric forms. It's the ideal activity to help children gain an understanding of balance and proportion, as well as interest in architecture, building, and design. Set includes: 200 pine planks and an idea booklet.

7 years & up. Construct tracks of tunnels, funnels, ramps, and chutes, then set the ball rolling and watch your creation come to life. The open-ended, no rules play promotes experimentation, creativity, and problem solving, which are key mental skills for aspiring young engineers and architects. As children build through trial and error, they gain an early understanding of physics and engineering concepts like balance and structural stability. No glue and no connectors means structures are vulnerable… More »
