This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

Coins are everyday objects which tell a lot about the people who use them.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

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

In this activity, learners construct a home-made journal with simple, everyday materials.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this story time program, young learners listen to the Dr.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

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, learners imagine what the world might look like if we could build an elevator to space!

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
