Mirror, Mirror on the Wall: Angles of Reflection
Source Institutions
In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Light Soda
Source Institutions
In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.
Exploring Structures: Butterfly
Source Institutions
In this activity, learners investigate how some butterfly wings get their color.
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
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.
Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!
Source Institutions
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
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.
Cylindrical Mirror
Source Institutions
In this activity, learners create a cylindrical mirror to see themselves as others see them.
Periscope
Source Institutions
In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
Vanishing Rods
Source Institutions
This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.
DIY Sunprints
Source Institutions
In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.
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 Three Little Pigments: Science activity that demonstrates the primary and secondary colors of lightScience activity that demonstrates the primary and secondary colors of light The Three Little Pigments Know your C, M, Y, and K.
Source Institutions
Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.
The Blind Spot
Source Institutions
In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.
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.
Make a Garbage Bag Kite
Source Institutions
Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!
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.
