Here are some photos of sample pin-hole cameras used previously in my classroom:

There is nothing inside of these samples, only wax paper screen, a small piece of tin foil with a tiny pin hole in the middle and tape etc to prevent any light from entering any other parts of the camera (other than the pin-hole and the wax screen).

Using the example photos and information above, please build your own pin-hole camera.

The wax paper should cover one end of the box entirely and should be tight and wrinkle-free.

The opposite side should have a small square hole cut out of the middle and should be approximately 2 cm by 2 cm square. This small hole should then be covered with a small piece of tin foil. The tin foil should also be wrinkle-free and smooth.

Using a small pin, create a small hole in the middle of the piece of tin foil by gently pushing the pin straight in and out, The hole should be the same size as the pin.

If a shoe box cannot be used, try a Kleenex box with the top blacked-out or a similar sized box.

Please E-mail me photos of your completed camera, then download the lab from the science page and complete. You may e-mail me questions if you have any. E-mail me the completed lab including the answers to your questions once completed.

If you are able, you can work in small groups up to 3 people or do individually. Good luck!!

Note:

When testing your camera, please use a candle and a dark room. Hold the camera at arms-length and point the pin-hole towards the lit candle. Move the box (camera) around up and down and back and forth until an image of the flame appears on the wax paper.

Please follow the lab instructions and answer all of the questions at the bottom of the lab while testing the camera.

Note: Do not make the pin hole larger until you have answered the other lab questions as these other questions require the pin hole to be the same size as the pin itself.

When all aspects of the lab have been completed, please save in your documents and e-mail me your completed lab.
