I get a charge out of this. In order to learn how a generator works, groups build and test one in this ninth lesson of the series. The generators are tested at low speed and high speed to determine the watt output and whether they have...

A solar cell is similar to a rechargeable battery in many ways. Science lab groups connect each in a series circuit to run a mini motor and then compare and contrast them by answering questions and completing a Venn diagram. This is an...

An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...

Eddy currents, Faraday's Law and Lenz's Law provide the connection between train brakes and and MRI machines in a lesson that asks teachers to provided the material needed so the pupils can understand the properties of changing magnetic...
