Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Night Lights
Source Institutions
In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.
Science of Sunblock
Source Institutions
This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl
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.
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.
Wandering Wands
Source Institutions
In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.
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.
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!
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
Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.
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.
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.
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.
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.
