In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

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

In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

In this online simulation, learners use antibiotics to cure patients with bacterial infections.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this neuroscience activity (4th activity on the page), learners make their own set of Von Frey hairs to test detection thresholds.

In this activity, learners explore the "nuts and bolts" of gene chips.

This quiz lets you estimate your annual radiation exposure.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.
