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 activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

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.

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

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 about light and reflection, learners discover that what you see is often affected by what you expect to see.

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

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

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

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

Learners use Duplo bricks to build antibodies with shapes that match model viruses.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

In this activity about olfaction (8th activity on the page), learners smell 10 different items with different odors. Then they try to identify the smells when they are mixed together.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.
