Gelatin Prism
Source Institutions
In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.
Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
Three Colors of Light
Source Institutions
Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.
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.
Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
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.
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.
Big Wave
Source Institutions
This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.
Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
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.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Tasty Buds
Source Institutions
In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Spots, Lines and Lasers
Source Institutions
Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
