Underwater ROV
Source Institutions
In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).
Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
Magic Wand
Source Institutions
In this activity about light and perception, learners create pictures in thin air.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
First Impressions
Source Institutions
Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
Camera Projector
Source Institutions
In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.
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!
Spinning Illusions
Source Institutions
In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.
Bike Wheel Zoetrope
Source Institutions
In this activity (posted on April 18, 2011), learners follow the steps to construct a zoetrope, a device that produces an illusion of action from a rapid succession of static pictures, using a 16" bik
Bring it into Focus
Source Institutions
In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.
Stroboscope
Source Institutions
In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.
Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl
Size Wheel
Source Institutions
In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).
Aerial Imagery
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.
