This is an activity about our sense of smell and how it compares to sharks' super noses. Learners will create varying solutions of water and perfume.

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.

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

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

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