Glowing in the Dark
Source Institutions
In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Social Fireflies: Pico "Firefly" Communication
Source Institutions
Make two firefly lanterns, then program them to blink to one another and change colors.
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.
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.
Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.
Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.
Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
Light and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
Exploring Earth: Temperature Mapping
Source Institutions
This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
Infrared Investigations
Source Institutions
In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
