Mozart and spatial-temporal reasoning
This science fair project was performed to ascertain if listening to Mozart helps to improve spatial-temporal reasoning and if so, how lasting is this effect. The science project experiment involved hamsters that were made to listen to Mozart for 12 weeks.
Effect of electricity on plant growth
This science fair project was conducted to find out how electricity affects the growth of plants. The experiment was done by supplying DC 9V to the soil containing radish seeds and observing the rate of plant growth.
DC motor energy loss
This experiment was conducted to find the amount of energy lost due to friction in DC motors. The testing was done using 30 watt, 50 watt, 70 watt and 100 watt DC motors.
How to build a magnetic linear accelerator
This very simple toy uses a magnetic chain reaction to launch a steel marble at a target at high speed. The toy is very simple to build, going together in minutes, and is very simple to understand and explain, and yet fascinating to watch and to use.
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
How to build a levitating train using magnets
This is a great demonstration of like poles repelling each other. We have a platform which floats above a pair of magnetic tracks, and can be gently pushed to one end or the other. This is similar in concept to the MAGLEV trains which are being worked on in Germany, Japan and France
What effect do magnets have on the growth of seedlings?
The purpose of this experiment is to determine whether magnets have an effect on the growth of radish seedlings. I became interested in the study of the effect magnets, when I discovered that magnets could make you heal faster. Later I decided that that it would be a better idea to study the effect of magnets on plants to keep it a safe experiment.
How do magnetic field lines look like?
Iron filings align themselves in strong magnetic fields. This reveals the shape of the field patterns. A similar thing happens with the electric fields created by high voltage and by "static electricity." If small fibers are exposed to a very strong electric or magnetic field, they will align with the field and make it visible.
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.
