How can You Demonstrate the Efficiency of Different Light Bulbs?
Source Institutions
In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.
The Primary Colors of Light
Source Institutions
In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.
The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.
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 and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
Star Power
Source Institutions
In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.
Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.
See the World Through Color-Filtering Lenses
Source Institutions
In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.
It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
Luminescence
Source Institutions
In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.
The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Rainbow in the Room
Source Institutions
This activity generates learner excitement about light through the creation of a room-sized rainbow.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Liquid Crystals Interact with Light!
Source Institutions
In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.
Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Cardboard Opaque Projector
Source Institutions
In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
Paint by the Numbers
Source Institutions
In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.
