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.
Light Quest
Source Institutions
Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable
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.
Polarized Light Mosaic
Source Institutions
In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required
Reflections
Source Institutions
In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Shadow Puppets
Source Institutions
In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.
Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.
Total Internal Reflection
Source Institutions
In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
The Three Little Pigments: Science activity that demonstrates the primary and secondary colors of lightScience activity that demonstrates the primary and secondary colors of light The Three Little Pigments Know your C, M, Y, and K.
Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!
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.
Multiple Reflections
Source Institutions
In this activity, learners explore how mirrors reflect light and change the way we see things.
Cardboard Box Camera Obscura
Source Institutions
In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.
Telescoping Periscope
Source Institutions
In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.
