In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

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

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

In this activity, learners use simple materials to create giant bubbles.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

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 make different shapes that hold exactly one mole of gas (air).

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

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.
