Pin Hole Camera

      
                                               ★Pin Hole Camera★ 

* This experiment is used to teach about optics in physics. Through Pin Hole Camera, kids can learn the concept of the function of the eyes (upside down effect due to light that passes through a small hole).

                          

★ Time: about 10 minutes (including setup and cleanup)

★ Cost: $ 0.00            (if all the materials are provided)

               $ 0.20            a piece of dark paper (best color black)

               $ 0.50            scotch tape

             * options for container

               $ 1.75            a pringles container

               $ 0.20            a piece of dark paper

               $ 0.00 (free)  a container found from garbage

             * options for a translucent cover

              $ 2.50            a roll of wax paper (but only a piece is needed)

              $ 0.00            a cover of pringles (comes with pringles)

              $ 0.00            a translucent cover found from garbage

             Total Cost: about $ 0.70 - $ 3.20

         ★ Area of Science and Topic: Physics (with Biology application)

★ Learning objectives: Students will understand the path of light.

                                          Studens will understand how eyes perceive things.

★ Materials:  

                        1 piece of dark paper (best color black)

                        1 pringles container

                        1 cover of pringles

                        1 sharp object such as screw driver (to put a hole)

                        1 scotch tape

★ Procedure:

Figure 1. Roll the black piece of paper into a cylinder shape

                       Then, use scotch tape to make it into a cylinder (shape)

Figure 2. Result of the procedure done in Figure 1

Figure 3. Put the small piece of translucent cover on the 

         cylinder shape thing (product in Figure 2)

Figure 4. Result of Figure 3

Figure 5. Make a small hole on the bottom of 

                  Pringles container with a sharp object

Figure 6. Put the product (Figure 4) inside the Pringles container

                      (the translucent cover facing or placed inside the container)

* Moving the black cylinder shaped thing (pulling out and in), observe an object placed under           the sun. A strong light such as sunlight is needed in this experiment to observe upside-down view of the object.

*Some good options for the object to be observed:   curtain (when the sun hits the curtain)

                                                                            candle

★ Tips for making the experiment work best with kids:

             a) Do not push the camera when someone is looking through it.
             b) Let the kids finish the snack before using it for the experiment.
             c) Wash the can of Pringles before using it for the experiment.
