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

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

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

This activity is about collecting and analyzing DNA as part of a criminal investigation.

This is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity, learners are asked to examine the differences between two materials in a pair.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.
