Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
