"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

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

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
