In this activity, learners make their own heat waves in an aquarium.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

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

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

In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

This activity is about how you form mental images of your body's position in space, independent of vision. Can you take a sip of water from a cup with your eyes closed?

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

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

In this activity, learners use simple materials to create giant bubbles.

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

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

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this activity about sea otters, learners make their own "otter whiskers" and use them to find objects underwater.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.
