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

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners will explore surface tension, what it is, and how we can change it.

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 will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

In this optics activity, learners explore how light bends and affects what we see.

In the kitchen, learners can perform their own density investigation.

Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners explore the flexibility of polymer chains by pushing sharpened pencils through a Ziploc bag.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity, learners discover how sweating makes us feel cooler. Learners put on one damp sock and one dry sock and sit in front of a fan.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
