Is it possible to collect micrometeorites from the outdoors?
Collect micrometeorites from indoor and outdoor sources.

How to build an extremely sensitive electroscope for detecting static electricity
This simple circuit can detect the invisible fields of voltage which surround all electrified objects. It acts as an electronic "electroscope."

How does a change in temperature affect the current, voltage and power generated by a solar cell?
The purpose of this experiment was to determine how different temperatures affected the voltage (mV), the current (mA), and the power (watt) generation of a solar cell.

How to build a simple electric generator
This is an AC electric generator which is capable of lighting up a tiny incandescent light bulb. The generator is made up of a hollow-ended cardboard box with a nail through the center, many turns of copper wire wound around the box, and four larger magnets clamped around the nail. When the nail and magnets are spun fast by hand, the little light bulb lights up dimly.

How to build a wind turbine generator
These plans are for the construction of a machine called a Savonius wind turbine. Wind turbines come in two general types, those whose main turning shaft is horizontal and points into the wind, and those with a vertical shaft that points up. The Savonius is an example of the vertical axis type. It consists of two simple scoops that catch the wind and cause the shaft to turn.

How to build a lightning storm detector (Franklin's Bells)
The toy is a high voltage motor that acts like a bell, with a clapper that bangs furiously from one can to the other and back again, sometimes several times per second.

What sort of blade design works best for windmills?
The purpose of this experiment was to determine which windmill blade sizes, shapes, and angles were most efficient at producing an electrical current from a generator.

Construct a model of a magnetically levitated train
I'm a science hobbyist and occasional exhibit designer for science museums. The devices shown here were part of a prototype "room-temperature superconductive table" which never made it to a museum. I thought I'd place it here so students and hobbyists could experiment with this strange maglev effect.

How does the pulse relate to the heartbeat and how does it differ when the body is in different positions?
Take your pulse at mutiple sites. Relate the pulse to heartbeat.

What are the best places on your body to meassure your pulse?
The pulse represents the variation in blood pressure from diastole to systole. During diastole blood pressure falls, but increases after systole as the heart pumps more blood into the arteries. You feel this difference when taking your pulse. Doctors use a device called a sphygmomanometer
