Light and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
Light on Other Planets
Source Institutions
In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe
Light Bulb Challenge
Source Institutions
In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.
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.
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.
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.
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.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
What is Nanotechnology?
Source Institutions
In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.
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.
Super Sleuths
Source Institutions
In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection
The Senses of "Unknown Creatures"
Source Institutions
In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
Iridescent Art
Source Institutions
This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.
LEGO Orrery
Source Institutions
Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.
How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.
