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.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.
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!
Seeing in the Dark
Source Institutions
In this activity (17th on the page), learners investigate why you cannot see colors in dim light.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Fruity Electricity
Source Institutions
In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.
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.
How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.
Gelatin Optic Fibers
Source Institutions
In this activity, learners make optical fibers out of strips of gelatin.
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.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
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
Sliding Gray Step
Source Institutions
How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.
CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
X-Ray Spectra
Source Institutions
In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.
Can Energy be Created or Destroyed?
Source Institutions
In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
