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 activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

Players take turns adding shapes made of three squares to a grid. They try to fit their shapes on the grid in a way that blocks the other player.

In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this activity learners will create paint out of natural materials. Explore your natural world (or your fridge) and find berries, leaves, or flowers to find a great base for your paint.

In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.

As learners play this strategy game, they develop understanding of squares, area, and perimeter. On each turn, a player draws a line between two dots next to each other on the grid.

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

In this activity, learners examine body parts (including skin, scales, and skulls) from fish, mammals and reptiles. Questions are provided to help encourage learner investigations.

In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

In this activity, kids make and play with Ooze before testing the material in an egg drop!

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

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.
