Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
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.
Terrestrial Hi-Lo Hunt
Source Institutions
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.
Sensory Hi-Lo Hunt
Source Institutions
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.
Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Cook Food Using the Sun
Source Institutions
Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Mini Glacier Meltdown
Source Institutions
This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation about the different causes of glacial melt.
Aviary Architect
Source Institutions
In this activity, learners are challenged to design, build and test a birdhouse that will stay cool in the sun.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
