Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

In this activity, learners build a carousel toy that spins when pushed down.

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

This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move?

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

In this activity, learners build inexpensive pulley assemblies from pulley wheels used for sliding screen door replacement or from clothesline spreaders.
