The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

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

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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

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

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

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

Everybody loves bubbles, and this is the best bubble recipe ever!

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

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

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

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

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.
