In this activity, learners explore their eye pupils and how they change.

In this online Flash game, learners will explore a coral reef using an underwater remotely operated vehicle (ROV).

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

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!

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

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.

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.

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.
