In this physics activity about rotational inertia, learners use a spinning top made out of a bottle cap and a nail to explore how changing the axis of rotation affects how the energy is used.

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 make a Benham Top to explore visual illusions and optics.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

Learners build at least two different spinners (tops) to investigate how mass distribution, size, and shape affect the length of time the spinner spins.

In this math lesson, learners explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and a graphing calculator.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.

In this activity, learners will make a thaumatrope, an old-fashioned optical illusion that dates back to the 1820s.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this indoor or outdoor demonstration, use a large and small ball to illustrate conservation of energy and momentum.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
