pollute our water and how it can be purified. With this kit you
will be able to test the level of bacteria in water, the chloride
content, the pH level and the rate at which particles settle in
water. (13-1/2" x 10" x 2-3/4"; 2Ibs).

and laboratory equipment leads students carefully through water quality experiments involving dissolved oxygen, the bacteria related to dissolve oxygen, water clarity, and the treatment of organic wastes.
(15-1/2" x 11-1/2" x 4"; 1Ib).
Environmental Pollution Kit Teach about environmental pollution in a more active way! A classroom size kit for the investigation of health and economic consequences of environmental pollution. The lecture materials contain discussions of chemical composition of fresh air and water, pollutants of the environment, consequences of environmental pollution and treatment and control of pollution. Classroom activities are separated into two categories: air and water pollution. Fifteen activities are performed; five dealing with air pollution and ten dealing with water pollution. The water pollution activities include determination of dissolved oxygen, addition of oxygen by aeration and by photosynthesis, removal of oxygen by heating, by respiration and by chemical activity, relationship between bacteria and oxygen, sewage and plant nutrients, treatment of chemical wastes, mine acid pollutants and their effects on fish.
This portable and versatile self-contained unit consists of a strong, transparent plastic jar, a depression manometer with scale down to 600mm Hg, double-clousing valve, and perforated vacuum plate with a rubber gasket, and a hand-driven air pump.
This battery holder provides a convenient way to hook up a 1.5-volt battery to your electrical experiment. Includes a PVC base and binding posts. (3-1/2" x 3-1/2" x 2-3/4"; .05Ib).

Teach cloud formation when
there's not a cloud in the
sky! This apparatus duplicates
atmospheric conditions during cloud
formation. It consists of a special glass flask
with a rubber hose connection, pinch clamp,
and large, thick walled, rubber bulb. When
the atmospheric pressure is lowered, smoke
particles are introduced into the chamber,
and a nucleus for the formation of water
droplets is produced. By compressing and
suddenly releasing the bulb, a dense cloud
forms in the flask. (10-1/4" x 6-1/4" x 6-1/4"; 1lb).
This demonstration helps emphasize the
relationship between temperature and pressure.
Clouds form when the pressure is suddenly
reduced inside the chamber. The water vapor is
condensed and forms a cloud around the smoke
particles. The thermometer is used to measure
the change in temperature when pressure is
introduced. This unit is mounted on an acrylic
base, with two upright steel rods and a crosspiece
to hold the stopper in place when air in the cloud
chamber is under pressure. (6" x 4" base x 8-1/4"; 2Ibs).
Let your students determine the dew point of the surrounding air and
calculate the relative humidity without having to experiment at the crack
of dawn! The unit utilizes an aspirator bulb to pump air through a liquid,
such as alcohol, which lowers the temperature until the dew point is
reached. The dew point can be seen as a film of moisture that builds up
on the outside of the nickel-plated cup that is used to hold the alcohol.
The cooling caused by the evaporation of the alcohol is what produces
the moisture. The thermometer is used to measure the temperature
when the dew point occurs. Consists of a chrome tube on a plastic base,
thermometer, air bulb, and inlet tube and instructions.
(3-1/2" x 3-1/2" base x 13"; 2Ibs).
