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

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

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

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

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.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
