In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this activity (12th activity on the page), learners conduct an experiment to demonstrate how muscles are constantly feeding information to the brain about what they are doing.

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.

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

In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

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

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.
