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

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 water behaves differently when it comes in contact with "nano sand" and regular sand.

In this math activity, learners play a game similar to 20 Questions, in which learners must identify a secret number drawn from a bag.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

This demonstration activity models how Venus appears from Earth.

In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

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 investigate what happens when you build up static electricity on plastic balls.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

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

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

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

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 explore surface tension, what it is, and how we can change it.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.
