This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

This activity (on page 2) explores how sensing is part of robotics. Learners try tying their shoes with different constraints.

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

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.

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

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

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 will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

Make a copy of the first stethoscope with only a cardboard tube! René Laennec invented the first stethoscope in 1819 using an actual paper tube!

Are fingers the only place on the body where we use our sense of touch? In this activity (6th activity on the page), learners test the touch sensitivity of different parts of the body.
