To study and demonstrate heat absorption and radiation. Consists of two metal concave plates one white and the other painted black with thermometer holders on the back, and in-between is a lamp, heat source. When the lamp is switched on and the temperature is measured of the metal plates, it can be studied which one absorbs heat quicker and more than the other. After the lamp is turned off, we can also study which losses heat quicker. Lamp operates on 12VDC. Base Size 7.75" x 7.75" x 0.5". Metal plates are 3.75" in dia. Total height of unit 5.5". One bulb included, thermometers not included.

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.
