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 sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

In this activity, learners explore materials through paper chromatography.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

In this activity, learners explore the relative size of the Sun and Earth as well as the distance between them.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

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

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

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this math activity, learners guess which cereals contain the most sugar. Learners use the nutrition labels on the cereal boxes to find the cereal with the least amount of sugar.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

In this activity, learners use sieves with different-sized holes to sort balls by size.

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

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

Combine la lógica y los números en este juego para todas las edades.

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.
