Several hands-on experiments are logged here, where students can learn about magnetism and electricity by building their own circuits, playing with compasses and magnets, or simply observing the properties of magnetism and recording them on a student worksheet.
The air we breathe, the water we drink, the soil from which we grow our vegetables... All of these items are recycled by nature. Find out how in this online exhibition.
Here you can explore the physics of the inclined plane. For the mass M, we show all forces, gravity and normal force, acting on it. As you change the angle, you can see how the components of the forces change.
Students will build a magnetic field viewing bottle from baby oil and steel wool fibers to see the magnetic field align with a magnet. A similar experiment is offered to make an electric field viewing bottle; both experiments yield dramatic results for elementary students. The second link above offers
