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.

Kit contains 15 sterilized, wrapped warn owl pellets; 1 owl pellet Teacher's guide; 1 bone-sorting poster; 1 vole skeleton poster and 1 food web poster.
Provide your classroom with an unforgettable, hands-on lesson on ecology and the food chain. Your students will dissect owl pellets to study the skeletal remains of the raptor's prey and, using a dichotomous key, identify the species consumed. Also construct a rodent skeleton from the recovered skeletal prey. With their findings, students will construct a food web, compiling a summary of the owl's diet in order to estimate the diversity of the prey available in the ecosystem.
Great for creating terrariums, small aquariums, or as a "critter" cage. Solves the cracking and breakage problem of rigid plastic and glass tanks. Unique features include nestable to save storage space, flexible, shatterproof material, molded foot pegs that prevent scratching and temperature transfer, rounded corners for easy clean up, and no-drip cover. Exclusive design forces condensation to remain in the tank.
Multiple program timer turns on automatically two or more times in 24 hours. Grounded for safety when used in three-prong electrical outlets.

Have you ever wondered how a weather forecaster knows what the weather will be like? In All About Meteorology, young students will see how meteorologists can predict the weather for the upcoming week and even a few months down the road through scientific deduction and high-tech equipment. Students will visit with Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, to get an up-close look at the equipment that meteorologists use to forecast the weather and explore such concepts as the water cycle and air pressure. Through a fun, hands-on demonstration, see how students can set up their own mini-weather station to monitor conditions in their own areas. Part of the multivolume Weather for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
This program looks at the wide range of climates in North America and around the world, and examines how factors such as the sun, wind, temperature, precipitation and position of Earth determine the weather for a particular region. Live footage, vivid graphics and a hands-on experiment help to clearly illustrate these concepts. One of six volumes in the Weather Fundamentals DVD Series in the Schlessinger Science Library.
