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.

The purpose of this experiment was to determine the dissolution times of three different pain relievers, comparing brand names to generic names. The information gained from this experiment would benefit society; by informing them which pain reliever is more easily dissolved.

In this experiment we'll create an object called a electrophorus (greek word for charge carrier). Using the materials listed above, we'll charge the object and then discharge it creating a snap, a little electrical shock, and a bright spark. If you're afraid of a little electrical shock then get Dad to discharge the object for you. And for grins, don't tell Dad beforehand about the resulting sp

The purpose of this experiment was to test the effects of acid rain on several generations of living organisms. This researcher was interested in exploring whether mutations, found in an acid environment would also be observed if the offspring were removed from the acid environment into a neutral environment. Drosophila melanogaster were selected as subjects, due to their short life span, ease

The simplest wireless telegraph set consists of a means of generating and controlling a spark which sends out radio waves into the air, and a receiver or detector to detect the radio waves. Probably the simplest way to generate and control a spark is to use a switch (called a telegraph key) to turn on and off a buzzer which generates sparks. The simplest way to receive or detect the radio waves

This research project aims to investigate a possible link between the biological basis for allergy to cows' milk and the general rise in allergies among children. The aim of this project is to see if there is an association between the behaviour of certain immune cells in children who are allergic to cowsÂ’ milk and the general increase in development of allergies of all kinds among children.

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.

This page presents a "basement science" experiment which reveals the universality of gravitation by demonstrating the gravitational attraction between palpable objects on the human scale. The experiment deliberately uses only the crudest and most commonplace materials, permitting anybody who's so inclined to perform it. Einstein's 1915 theory of General Relativity explains gravitation

. Some scientists believe that ocean levels may rise, ice caps could melt, droughts could occur, climates may change, and that life in general would be greatly affected.
