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.

Comparative Anatomy: Dissection uses systematics and anatomy to illustrate the similarities and differences of systems in different organisms. Students learn how advances in medicine have come from the careful study of organs and have an opportunity to discuss the ethical codes of scientists. Through a lab investigation, students become comfortable with the scientific tools and habits of mind used in the fields of gross anatomy and histology. Part of the multivolume Science Lab Investigations! DVD Series. Includes a Teacher's Guide.
This is the True and Correct Compound Bar, in which 2 metals of unequal co-efficient of expansion are used to show unequal expansion. Consists of 2 strips, brass and steel riveted together from end to end fitted to a wooden handle. On heating, the joined strips bend in a particular direction thereby showing unequal expansion. Instructions included.

Demonstrates the difference in thermal conductivity of different metals. Consists of five metal rods stainless steel, brass, copper, iron and aluminum connected to a center metal, brass, hub which is mounted on a rod with wooden handle. The five rods have depressions on the ends to hold wax. When the center hub is heated, heat is conducted through the rods and conductivity of heat can be ascertained by the melting of wax.

When used with traffic cones and plastic chain, the Cone Chain Connector easily slips over the top of the traffic cone to create an instant, highly visible barrier. Featuring four-hook accessibility, the chain can be attached in a 90-degree angle or a straight line. The connector is strong, durable and adaptable to most cone sizes. Create effective visual barriers in pedestrian traffic zones, manufacturing plants, construction sites and more. The Cone Chain Connector, when used with our chain, complies with OSHA's standards for visual barriers. Each kit contains 6 Cone Chain Connectors and 50' of matching plastic chain.
