In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity, learners will investigate static electricity as they create waterless snow globes.

In this activity, learners take apart a used zinc-carbon dry cell battery.

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

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

In this activity, learners investigate static electricity using everyday objects at four different stations.

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

In this simple activity, learners create an electroscope by sticking two short pieces of magic tape together and then pulling them apart to find the sign of the charge on an unknown charged object.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

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