Pupil
Source Institutions
In this activity, learners explore their eye pupils and how they change.
Physics in a Glass: Reversing Arrows
Source Institutions
In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.
Polarized Light
Source Institutions
In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.
Three Circles of Pigments
Source Institutions
In this activity, learners overlap the three primary colors to see how all other colors are made.
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.
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.
Fun with Flatware: Little Experiments to Try at the Dinner Table
Source Institutions
This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.
Release the Rainbow
Source Institutions
In this activity, learners create a water prism to break light into the seven colors of the rainbow.
Guiding Light
Source Institutions
In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).
Color Vision
Source Institutions
In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.
Accommodating Accommodation
Source Institutions
In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.
The Shadow Knows I
Source Institutions
In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.
Mix-N-Match Light
Source Institutions
This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.
Total Internal Reflection
Source Institutions
In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
Can You "See" Thermal Radiation?
Source Institutions
Use this hands-on activity to demonstrate infrared and thermal radiation.
