See the Light
Source Institutions
In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.
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.
Light and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
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.
Colored Shadows Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.
Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.
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.
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.
Pupil to Pupil
Source Institutions
In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.
Easy PEAsy Seed Germination
Source Institutions
In this activity, learners determine the necessary conditions for pea seed germination.
Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
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.
How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.
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.
Coffee Filter Rainbows
Source Institutions
In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.
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
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
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.
