This apparatus is used to demonstrate and teach the basic principle of an electric meter. Apparatus consists of a 3.75" (90mm) dia. air coil wound on an acrylic tube with an acrylic plate in the center to hold a compass. The coil has multiple tappings of 50, 100 and 200 turns, and also has a built-in potentiometer for varying the current, these features allow multiple readings. Operates on one "AA" battery (not included). Includes one compass. Base 7.34" (195mm) x 4.75" (120mm) x 0.5" (12mm). Total height 4.25" (110mm).
This kit allows students to explore the electrical properties of different combinations of electrode materials using safe, everyday chemicals such as soda, vinegar, and fruit juice as electrolytes. The set contains everything needed for the experiments except the electrolytes. Voltage, current, and polarization effects can be investigated. Contents of the set include a simple cell with electrode holders, electrodes of copper, aluminum, iron, and zinc, a mounted resistor for use as a current load, a multimeter, and a manual.
Used to power portable radios, cassette players, children's toys and other situations where four C, AA or AAA cells are used. Size: 6.375 x 4.5 x 0.375" 11 oz. The F6220 includes a 12 foot cord, DC adapter jacks and jumper cord.
Expand student's understanding of energy costs with this model of a passive solar house. The 11" x 11" x 8" model comes with a detailed Teacher's Guide containing activities in basic science, solar energy, and energy conservation. Grades 3-9.

When is a bicycle wheel a gyroscope? When you put a new "spin" on it. Give our bicycle wheel a spin, then try to tilt or deflect it. Our student-sized bicycle wheel turns freely on its axis and has large, comfortable handles at each end. Because mass is concentrated at the rim, you can tilt the spinning wheel to feel the force of rotation. With instructions.

Push the cart and eject the steel ball from the spring-loaded barrel. The ball falls back into the barrel of the moving car, demonstrating that the forward motion of the ball is the same as the vehicle from which it was ejected. Comes with a steel ball, release pin and cord. The barrel permits two different heights of ball flight.

A compact and economical Color Mixing Apparatus. This updated version of the classic three color light projector uses three low voltage, high power LED's to project easily-seen red, green, and blue light onto a white screen. The projector mounting allows the beam angles to be adjusted to vary the overlap of the three colored images. The intensity of each LED can be adjusted separately by a potentiometer to give a convincing white light or various shades of mixed colors. Colored shadows can also be explored in a darkened room. The set includes a wall mount power supply and manual.
