Colored Shadows
Source Institutions
In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.
Measure the Sun's Size
Source Institutions
In this activity, learners make their own pinhole viewer in order to measure the size of the sun.
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
Marble Mazes
Source Institutions
In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.
Shimmering Lenses
Source Institutions
In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.
Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.
Reflections
Source Institutions
In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.
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!
Circles or Ovals?
Source Institutions
This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?
Phantom Phlame
Source Institutions
In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.
Diffraction Between Wax Blocks
Source Institutions
In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.
Shadow Puppets
Source Institutions
If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.
Wandering Wands
Source Institutions
In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.
Plants Around a Building
Source Institutions
In this outdoor activity, learners discover how the environment around a building affects the growth of plants.
Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.
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.
Afterimage
Source Institutions
In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.
