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.
Amazing Albedo
Source Institutions
In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.
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.
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
Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
Can You "See" Thermal Radiation?
Source Institutions
Use this hands-on activity to demonstrate infrared and thermal radiation.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
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.
Exploring Earth: Temperature Mapping
Source Institutions
This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
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.
