2. Solar Eclipse – How to Build a Pin-Hole Camera

Solar Eclipse

A solar eclipse occurs when the Moon stands between Earth and the Sun.

The Moon can fully or partially block the Sun, as seen from Earth. When  the Moon fully blocks the Sun, it’s called a total eclipse. When the Moon partially blocks the Sun, it’s a partial eclipse.

 

 

We can see the Sun eclipse just from certain locations of the planet, depending on where the shadow of the Moon falls.

 

But be CAREFUL: even on an eclipse, the effects of the solar rays can be very bad for your eyes. There are safe ways to look at the eclipse.

 

Here, we are going to build a pin-hole camera, which is one of the ways to safely see the solar eclipse (ask an adult to help you).

This is what you will need: parchment paper, elastic band, scissors, tape, pin, and a box. The longer the box, the bigger and dimmer the image of the Sun will be.
Firstly, totally open one side of the box.
Secure all holes with tape – the interior of the box has to be dark.
Then, cut the parchment paper so that it’s slightly bigger than the side of the box. Cover the open side of the box with it (the parchment paper has to be secured with the elastic band, because it’s difficult to get tape to stick to it).
Punch a hole on the centre of the opposite side of the box, using the pin.
You can further secure the parchment paper with tape. And here’s your pin-hole camera!

 

You can test the camera by pointing at a light fixture at home (the parchment paper is closest to you). This is how the image of the light fixture will look like on your parchment paper screen: (note the the image will be upside down!)

 

In North America, we will be able to see the Solar Eclipse on Monday, August 21, 2017. For more information, please visit:
