This series of magnetism experiments provides kids with with several fun activities.  Build a magnetic field that’s stronger than the Earth’s.  Create an electromagnetic pendulum.  Create eddy-like currents of magnetism and explore what happens to magnets dropped in them.  Lots of experiments that could make an interesting start to a science project

This is a series of experiments with electricity and magnets designed for 4th graders.  They can be used to build experience so the students have some understanding of charges, electrostatic forces, circuits, magnets, electromagnets, and electric motors.

From site:  These pages deal with electric circuits, electrical energy, electrical energy production and electrical energy transmission. More specifically:

• We press a switch and we turn the lights on. How is this possible to be happening?
  Let’s construct a simple circuit.
  Let’s improve a bit the simple circuit we just created. Can we connect more light bulbs?
  If yes, in how many different ways can we do that?
  What do we mean by the term “induction”?
  How does an electromagnet work?
  What is electrical energy?
  How do we produce electrical energy? How is electrical energy coming to our houses?
  What is the function of a transformer?
