In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

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.

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 game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.

In this activity, learners will use their nose to sniff out hidden scents using extracts and cotton balls. Activity includes materials list, game instructions, STEM connections and more.
