Thermal & Chemical Pollution
Using yeast to represent oxygen consuming microorganisms or animals, the effect of temperature on biological oxygen demand and dissolved oxygen in water is explored, relating this to the metabolism of an organism. Further activities investigate chemical pollution by direct poisons (lead irons) and indirect (phosphate ions) that disrupt what lives in water by favoring the growth of one type of organism.

Enviromental Test Lab
Our kit includes extensive tests for evaluating both water and air quality. You will test for dissolved oxygen, water hardness, pH, phosphates, chlorides, lead, hydrogen sulfide, air particulates, gaseous pollutants and rain water chemistry. The kit allows for three repetitions of the testing of local environmental conditions in a variety of formats that might include demonstration, small group, and individual use.

Thermal Radiation Class Set
A 100 W incandescent lamp is the source of the energy that is explored in this investigation of reflection and absorption. In this classic experiment, a black metal can and a shiny metal can, each having an insulating cap with a thermometer mounted on it, are placed an equal distance from the lamp. Temperature changes are observed and investigated.
