Wind is one of the most promising sources of clean, renewable energy available today. With this kit, you can assemble a realistic wind turbine complete with electric generator and adjustable rotor blades that are designed with complex aerodynamic curves to look and work like modern-day wind turbine blades. Then, conduct experiments to optimize the turbine’s performance by adjusting the angle of the blades and discover how to use the wind turbine to light up an LED and charge a rechargeable battery. Convert the generator into an electric motor and assemble a small electric car to demonstrate a tangible application for the stored electricity.
The full-color, 32-page manual offers illustrated instructions and scientific information that explores the different types of wind turbines and windmills, the history of this technology, and how wind energy can be used to power homes and electric cars.

• Introductory chemistry set designed specifically for young kids
• Conduct experiments to identify different chemicals
• Discover the invisible gas carbon dioxide and its very visible effects
• 48-page manual guides young chemists through 25 experiments
Kick off a chain reaction of fun-filled experiments with this introductory chemistry set designed specifically for young kids. Junior chemists can safely explore simple chemistry using the tools in this kit and common household substances from the kitchen, bathroom, and laundry room. Learn how to use basic chemistry equipment such as filters, test tubes, pipettes, and measuring spoons, and beakers. Make your own test tube racks out of plaster and learn about the chemical reaction that formed them. Conduct experiments to identify different chemicals using reactions, heat, evaporation, and crystallization. Examine the composition of inks and dyes with chromatography experiments, where colors magically separate from one another on a filter paper disk. Explore the properties of water, soaps, and oils. Experiment with acids and bases using indicators (pH strips and cabbage juice) to identify them. Make fizzy reactions with acids and bases to dissolve shells and inflate balloons. Discover the invisible gas carbon dioxide and its very visible effects. The full-color, 48-page manual guides inquisitive young chemists and their adult supervisors through safely conducting each of the 25 experiments.
• This kit provides the tools and instructions to learn how electronics work.

Fun Circuit Building Experiments for Beginners Construct circuits with colorful electric building blocks to learn about electricity and how electronic devices work. With the innovative snap-together blocks in this kit, children eight and up can safely and easily begin experimenting with electronic circuits. These building blocks are specially designed to make learning electronics fun and accessible. Because the blocks are brightly colored and have unique shapes, it is easy to follow the assembly diagrams to construct functional circuits. And because the circuit symbols are printed directly onto the blocks, you can quickly become familiar with the symbols and learn how to read circuit diagrams. The fun building projects include an alternating blinker, a police siren, an ambulance siren, an alarm system, a light detector, a conductivity tester, a rain warning system, a timer, and logic circuits. The electronic components in this kit include capacitors, resistors, transistors, LEDs (light emitting diodes), a phototransistor, a switch, 30 contact blocks, cable blocks, a battery holder, a speaker, and a sound integrated circuit. The 64-page, full-color experiment manual guides you through 70 circuit building experiments with easy-to-follow diagrams. This kit provides kids with the tools and instructions they need to experiment with their own hands and learn firsthand how electronics work.

Physics Pro is our biggest, most advanced physics kit. With this kit, you can continue your study of statics and dynamics from previous lessons and begin your study of more advanced topics in physics, including fluid dynamics, energy, oscillation, hydraulics, and pneumatics. By adding advanced topics like fluid dynamics to your physics repertoire, you can now build some really spectacular models and devices, such as a wind tunnel, pneumatic shocks, and a hydraulic lift. You will see how physics extends far beyond the classroom, giving us an amazing set of tools that can be applied in the real world to engineer marvelous things. The main focus of the kit is the behavior of the two most important fluids in our world — water and air — and objects immersed in them. You will investigate how air and water rest and flow, what they can carry and how they move. With experiments and models, you will find out what forces work on them and what kinds of energy they possess. You will learn how ships float and airplanes fly, why a streamlined shape lets a car drive faster and how power plants convert a current of water into electrical current. The 96-page, full-color experiment manual has two major sections. In the first part, you will enter the physics lab, where you will get to know the properties of air and water and become familiar with currents and energy. There is a series of 17 experiments in which you will start building smaller models. In the second part, you will move on to the workshop, where you will build 14 larger models of complex real-world devices. More than 212 parts are included in this kit, which are compatible with our other Physics kits.

Serves to demonstrate Boyle's Law. Shows what happens when gases are subjected to increased pressure. The plastic syringe, with solid wood base and platen, is constructed so that the calibrations denoting interior volume read right side up. As masses of bricks, books, or other heavy objects are increased, the gas in the syringe is compressed to smaller and smaller volume. The kit includes: 1 Syringe Cylinder w/ Cap, 1 Syringe Piston, 1 Base, 1 Platen.
