In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners explore how nanosized structures can create brilliant color.

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 international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

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 observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
