In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this hands-on activity, learners investigate the functional design of leaves on a tree.

This is an activity exploring color and color mixing.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this math activity, learners experiment with the concept of symmetry.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

In this activity, learners investigate procedural memory.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners perform an experiment to find out what determines a flower's color.

In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
