Gyroscope Bicycle Wheel
Twist the handles of this spinning wheel to feel the gyroscopic motion and show why gyroscopes are used in stabilizers and navigational devices. Stand on a rotational turntable to demonstrate the conservation of angular momentum. Tie a rope to one handle to show that the wheel doesn’t fall over. Comes completely assembled and includes background information and activity instructions.
AP4610 | $116.75
Rotational Turntable,
Figure Skating Dumbbells—
Lab Stool
Demonstration Kit
Put a new spin on your angular momentum lesson! Stand on a rota- tional turntable holding dumbbells straight out. While slowly rotating, move the dumbbells as close to your body as possible. Your students will be astonished with how fast you spin—just like an Olympic figure skater. A reproducible student work- sheet, background information and instructions are provided.
AP6840 | $31.60
Rotational Turntable
Engineered to provide a low-friction rotating surface for experiments involving the conser- vation of angular momentum and rotational kinetic energy. Set on a level floor for stand- ing or placed on a stool for sitting. Supports up to 200 pounds. Use with a gyroscope bicy- cle wheel (AP4610) and conduct experiments on gyroscopic precision and torque or other demonstrations involving rotational motion.
AP4609 | $56.50
Safely demonstrate rotational motion while seated with your center of mass over the rotating platform, making it easier to main- tain balance. Seat is made with
the same low-friction hub as the stand-alone Rotational Turntable, AP4609. Interlocking wood parts can be easily disassembled and stored, or construct it permanently using the glue provided. Stands 65 cm tall. Seat diameter is 30 cm.
AP6438 | $138.55
Torque Feeler
Successfully teach the concept of the “rotating force,” or torque, with this unique device. First, place the hanging mass close to the gripping handle. Students will find it easy to hold the rod horizontal. Then, slide the same mass to the end of the rod—not even your stron- gest student will be able to grip tightly enough to prevent the handle from twisting in their hands! Effectively demonstrates how lever-arm distance influences the strength of a torque. Comes complete with instructions and 1-kg hooked mass.
