Remote Control Machines Kit
Build your own electric vehicles and machines and navigate them with a wire- less remote control! An innovative infrared remote control allows the user to control three different motors at the same time with easy-to-use touch sensors. Using step-by- step instructions, construct up to ten models, including a crane, three-wheeler, car, folding car, formula car, antique car, bulldozer, blade bulldozer, plow and a robot. Students can even build creations of their own design!
AP7815 I $86.45
Forces, Energy and Motion Model Set
Build six different models! Learn about potential and kinetic energy, gravity and speed with a gravity fan; how energy can be stored in a cord until converted to another form; momentum and Newton’s first law of inertia with a collision test car; centrifugal and centripetal force as well as energy conver- sion with a balloon-powered plane. Finally, construct a ballistic catapult to study how gravity affects the path of motion.
AP7918 I $64.85
Pulley Demonstration Kit, Economy Choice
Highly visible red pulleys can be seen from the back of the room for demonstrations. Purchase multiple sets for students to use
at lab stations—the price is affordable, and this equipment will last. Durable set includes all materials necessary to set up a variety
of experiments—metal pulleys, slotted weights, weight hangers, wheel and axle, string and a sturdy wooden base and metal frame. Includes instructions and sample experiments. 32" H x 32" W x 81⁄2" D.

K’NEX® STEM Explorations: Roller Coaster Building Set
Learn about the relationships between time, distance and speed with this engaging roller coaster building set. Students will have fun while learning about the science, technology, engineering and math concepts associated with a real-life amusement park ride! Build one working roller coaster, plus two addi- tional models. Includes three experiments, one for each model.
AP8697 I $39.95
Newtonian Demonstrator
This classic demonstrator is perfect for illus- trating Newton’s laws of motion and the conservation of momentum. Demonstrate nearly perfect elastic collisions. High-quality wooden construction. Measures 7" x 9" x 81⁄2" tall.
AP6913 I $34.95
Galileo ̓s Gravity Drop
Dispel the most common myth about fall- ing objects and gravity. Re-create Galileo’s legendary Leaning Tower of Pisa experiment with the unique gravity-drop apparatus.
The mechanism in the apparatus allows you to simultaneously and accurately drop two balls with different masses. Listen for the sound of them hitting the floor at the same time—a great introduction to Newton’s first and second laws of motion!
