How to build a magnetic linear acceleratorFeatured science project
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.
Difficulty: Elementary school
The effect of different Electrodes and Electrolytes on voltage Featured science projectScience project video
The purpose of this experiment is to find out what combination of electrodes and electrolytes gives out the highest voltage. This study is important for companies who produce batteries so that they will know which materials to use to yield the highest amount of electrical energy.
