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.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

“Exploring Earth: Rising Sea” is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

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 is written as a display, but can easily be adapted to a hands-on activity. Learners discover how all the parts of a diaper work together to keep babies dry and comfortable.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners will put a set of containers in order by capacity. Would the tallest container hold more or less water than the wide, short one?

Using household materials, learners can make white gooey globs from clear solutions. Alum, dissolved in water, reacts with the hydroxide in ammonia to create aluminum hydroxide.

In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
