Use this simple apparatus to measure relative humidity. Includes two plastic-backed Celsius thermometers, one for dry bulb measurements and the other for wet bulb measurements.

Our Sling Psychrometer Kit is a simple hygrometer used in measuring the moisture content in the air. When spun around on their wooden handle, the wet bulb thermometer and the dry bulb thermometer will read different temperatures.

The Snaky Spring is 2cm in diameter, 180cm long, and can be extended up to 5 meters. The spring is an excellent demonstration of wave theory concepts such as longitudinal waves and wave behavior.

This simple device gives a graphic demonstration of the sun&rsquos radiative energy. A large convex mirror concentrates solar radiation onto a small container of water suspended at the mirror&rsquos focal point.

The Solar Kit offers a convenient introduction to the conversion of solar light energy into electrical energy. The conversion is carried out by a photoelectric panel, and three &ldquoconsumers&rdquo are included to demonstrate the use of the
