In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.

In this activity related to computer programming, learners give directions to a "robot" (either an adult or another learner) and find out which instructions the robot is able to follow, and how their

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this interactive game, learners compare their music-listening skills with that of a three-month-old baby.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

In this activity, learners make a photographic image—without a camera!

In this activity, learners will be able to measure themselves in nanometers. A nanometer is a billionth of a meter, a unit of measurement used in nanotechnology.

Many people get water from a source deep underground, called groundwater.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.
