Thames and Kosmos Amazing Tightrope-Walking Gyrobot
17102

A robot fit for the circus! With this kit, you can build a robot that walks, step by step, along a tightrope. How? Thanks to the robot’s main component, a gyroscope, it can maintain its balance and perform this fun trick without falling over! Through eight experiments, you can explore the astonishing powers of the motorized gyroscope and understand the physics behind its amazing behaviors. Experiment with getting the robot to walk on different surfaces: a tightrope, on a solid tabletop, on a soft surface, and even on your arm! You can also experiment with the balancing behavior of the motorized gyroscope by itself, testing its ability to balance on its edge, on your finger, on a pole, and dangling from a string.

The kit includes parts to build the robot and experimental setups, including a frame for the tightrope. By constructing the robot and performing the experiments with the motorized gyroscope unit, young engineers can learn about the science of gyroscopic devices and the indispensable role they play in our lives.

A full-color, 24-page, illustrated experiment manual provides step-by-step assembly instructions and scientific explanations.

Discover the science of living things with this complete introductory microscope kit. The beautifully illustrated experiment manual guides you through observations of many living specimens found in and around your home: onion cells, pond water, chloroplasts, plant stem cross sections, microorganisms, mouth cells, meat cells, different types of hair and fur, dust mites, bugs, pollen in honey, and much more.

See how an onion cell shrivels and how an paramecium wiggles. Analyze the differences between the hair on your head and the sheep’s hair in your wool sweater. The kit includes slides, cover slips, and many helpful tools. Learn how to use these tools to prepare slides and how to use the microscope to examine them.

Investigate how the lenses in a microscope bend light to magnify images. When the ocular lens, or eyepiece lens, works together with the three objective lenses, the result is a total magnification power of 60x, 150x, or 600x. The microscope has a battery-powered light to light up the specimens. The full-color, 32-page manual covers microscope setup, usage, and many fascinating observations of biological specimens.
