 | How to build a homemade magnetometer to study how the earth's magnetic fields are affected by solar  Solar storms can affect the Earth's magnetic field causing small changes in its direction at the surface which are called 'magnetic storms'. A magnetometer operates like a sensitive compass and senses these slight changes. The soda bottle magnetometer is a simple device that can be built for under $5.00 which will let students monitor these changes in the magnetic field that occur inside | ||

 | Why is the sky blue? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. | ||

| Illustrate sea-floor spreading and subduction by building a model This report describes how to build a model of the outer 300 km (180 miles) of the Earth that can be used to develop a better understanding of the principal features of plate tectonics, including sea-floor spreading, the pattern of magnetic stripes frozen into the sea floor, transform faulting, thrust faulting, subduction, and volcanism. | ||

| Build a model to demonstrate how earthquakes are caused The apparatus consists of a heavy object that is dragged steadily with an elastic cord. Although pulled with a constant velocity, the heavy object repeatedly slides and then stops. A small vibration sensor, attached to a computer display, graphically monitors this intermittent motion. | ||

| How to build your own electric motor This home page features award-winning, easy-to-build, and inexpensive electric motors.
If you are looking for a simple science project, or if you wish to learn about electricity, magnetism, and electric motors, this web site has it all! Including assembly instructions, a section devoted to how these motors work, and I even provide all parts necessary to build them! The reed switch motor is the e | ||

| 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 create a heat engine with the help of magnetism I originally built this toy using a Canadian nickel coin. Canadian nickels are made of pure nickel, unlike U.S. nickels, which contain so much copper that they are not magnetic. You can build the toy with the nickel or with the Radio Shack rare-earth magnet. | ||

 | 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 to measure gravitational forced between masses 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 as spacetime | ||

| How quickly do different types of household fabrics burn? (Parental supervision needed) The purpose of my project is to find out more about the flammability of household fabrics used in the home, and maybe find a relationship between the size of the fabric, the length
of time that it was exposed to fire, and the length of time that it takes to burn. Since I picked out a lot of different kinds of fabric to test, I wasn't sure of what to expect. My
hypothesis states that most of | ||

Science kits, science lessons, science toys, maths toys, hobby kits,
science games and books - these are some of many products that can
help give your kid an edge in their science fair projects, and develop
a tremendous interest in the study of science. When shopping for
a science kit or other supplies, make sure that you carefully review
the features and quality of the products. Compare prices by going
to several online stores. Read product reviews online or refer to
magazines.
