In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

This lesson focuses on graphene and its electrical properties and applications.

In this activity, learners use water, oil, and food coloring to observe a chemical reaction that creates a shower of colors inside of a glass.

Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

In this activity, learners explore how engineers work in a team to solve problems.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
