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

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

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 activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

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.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

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.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

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

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this quick activity, learners practice locating a constellation in a map of very dark skies.

In this activity, learners create a "mini sky" in a glass of water in a dark room.
