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

This lesson focuses on how materials behave differently as their surface area increases.

In this activity, learners will use clear nail polish and the power of chemistry to create paper with a rainbow sheen.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

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.

Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

This is a simple and fun activity for learners to explore water and colors.

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

In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

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

In this activity, learners recrystallize substances from solutions and make observations about the resulting crystals. This test can help further identify the unknown.

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

In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

In this activity on page 11 of the PDF, learners use candle wax to make "invisible" designs that are revealed with watercolor paints.

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.
