In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

In this activity about light, learners explore how water can refract light and change the way they see things.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners discover how solar energy can be used to heat water.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

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

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

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 activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.

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