In this interactive game, learners will test their memory of animal and insect sounds. Flip over cards, listen to the sound, and try to find the ones that match.

In this activity, learners examine nanoscale structures of common things.

Learners explore their surroundings while reasoning about categories and counting.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners investigate the properties of graphene and graphite.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

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 will be making the opposite of a bubble, an anti bubble! This low start up activity is fun, informative, and best of all-a little messy!

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 will divide into teams or groups of equal size. “How many teams of three can we make?” “We need an equal number of children at each of the four computers.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

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

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

In this activity, learners will collect and analyze data to learn about the people around them. How many letters in everyone’s first name? What’s the most common number of letters?
