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.
Spectroscope
Source Institutions
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.
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
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.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Glow in the Dark
Source Institutions
Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.
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
Light and Dark
Source Institutions
Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.
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.
Light Box
Source Institutions
Learn how to construct a light box by following simple figures and instructions. This guide includes tips on how to assemble a light box; related activities are featured in separate resources.
