Maxwell's Wheel
Maxwell's Wheel
16247

Useful for demonstrating momentum, conservation of energy and torque! The unit is suspended by two strong cords, which are wound around the shaft of the wheel and then released. The wheel will unwind as it falls but will wind itself back up as the momentum carries the wheel upward in the opposite direction. This oscillation process will continue for several moments as the wheel slowly loses momentum and travels less each time. Instructions included.

Thames and Kosmos Ooze Labs: Soap & Bath Bomb Lab
17118

It’s time to start mixing things up! In this pretend STEM scenario, you are a chemist for a bath and body products company and it’s your job to make and test different cosmetic products. Use the tools in your laboratory to employ different scientific techniques and essential chemistry principles to make soaps and bath bombs. Try out different additives to affect the color, smell, and other qualities of the products you make.

Real science and pretend play come together in this activity-filled kit that can be used alone or as an extension of the Ooze Labs Chemistry Station (a Parents’ Choice Silver Honor winner!). As you mold different glycerin soap shapes, you learn about the chemical properties of soap that help it pick up and wash away dirt. While you’re concocting bath bombs, you learn about how acids and bases combine to form fizzing reactions, and what a pH level is. Expand your cosmetics knowledge with an overview of the biology of skin care and other science related to soap and bath products. All materials and chemicals are non-toxic.

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.

Thames and Kosmos Wind Power Kit
Thames and Kosmos Wind Power Kit
16778

• Build a realistic wind turbine to harness power out of thin air.
• Assemble a wind turbine complete with electric generator and adjustable blades
• Conduct experiments to optimize its performance by adjusting the blades
• Convert the wind turbine into an electric fan by using the electric generator
• Build three additional models with the parts included
• Conduct more than 20 experiments with your wind turbine

Build a working wind turbine to harness power out of thin air. Wind is one of the most promising sources of clean, renewable energy available today. Wind energy has been used for centuries to pump water and crush grain in windmills, and is now increasingly being used to generate electricity to power our modern world. Assemble a wind turbine complete with electric generator, adjustable rotors, and wind speed indicator. Conduct more than 20 experiments with your wind turbine. Use the wind turbine to generate mechanical power to lift a heavy weight or generate electricity. Learn the physics of force and motion as it applies to wind power technology. Learn how to measure and calculate the different forces acting on the rotor blades. Read about different types of wind turbines and windmills. The full-color, 32-page experiment manual included. Ages 8 and up.

Thames and Kosmos Hydropower Kit
16777

Hydropower has been used for hundreds of years in watermills and is now commonly used to generate electricity in applications such as hydroelectric dams and tidal power plants. Explore the power of water by building models and conducting experiments with them. Learn about how different devices are used to extract useful energy from moving water — from a waterwheel in a small stream to a giant turbine in a tidal power station.

Build a waterwheel, a sawmill, and a hammer mill to harness the energy of moving water to do different types of physical work. Investigate the intriguing properties of water by performing experiments involving surface tension, adhesion, and cohesion. Learn about water pressure by building a water tower, communicating vessels, and a water fountain.

Construct a hydroelectric power station to generate electricity and light an LED. Learn about where the energy in ocean waves, tides, and rivers comes from, and discover how we can generate electricity from them. The full-color, 32-page experiment manual offers illustrated instructions and scientific information.
