These colorful teaching models are designed specifically for hands-on use with young children. Made of resilient, non-toxic, EVA foam, the removable pieces stimulate problem-solving skills and develop small motor skills. Every model is accompanied by a reproducible activity card containing background information and extension ideas. teachers can cut out the task card and use it in learning center or as a group activity. These teaching models are designed to introduce students to lifecycles. The models illustrate the major stages of the life cycle, and encourage students to explore how these living things change as they grow. Grades K-8.

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.

To study Spectral Lines of Pure Elements / Gases. Gas under pressure in the tubes is used to produce a light for spectral analysis. Brightness of light depends on the nature of gas. Optimum intensity, line resolution and longer life. Metal ends with long life electrodes. About 26 cm long, with 90 -100 mm of central capillary. For intermittent use only, not to be used as a lamp source. These are designed to operate 30 seconds ON~30 seconds OFF. Need Spectrum Tube Power Supply or an Induction Coil, sold separately.

This kit is great for all doubting Thomases in your elementary through high school classes. Fast, fascinating and easy. This kit includes: Two black-colored blocks with rim for holding melting ice cube in place. The "cooler" one is of aluminum, which is an excellent conductor of heat. The ?warmer" block is of plastic foam, which is a very poor conductor of heat.
