In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

In this activity, learners build a seesaw powered by magnets.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
