In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

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

In this activity, learners compare different types of salt crystals under a magnifying glass.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

In this activity, learners explore their eye pupils and how they change.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

In this activity, learners discover that our hands are not reliable thermometers.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.
