What’s it about?

Eclipse means to overshadow something. A ‘lunar eclipse’ is caused by the earth blocking light to the moon while a solar eclipse occurs when the moon passes in a direct line between the Earth and the sun.

The moon’s shadow travels over the Earth’s surface and blocks out the sun’s light, as seen from that specific region on the Earth. It is very dangerous to look directly at the sun during a solar eclipse or any other time – in this science experiment, create a device for safely viewing a solar eclipse:

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

In this science experiment you created a type of ‘pinhole camera’, which allows you to view a projected image of the Sun. With this device, an inverted image of the Sun is formed on the bottom piece of cardboard. To make the image larger, move the screen farther from the pinhole.

This device is to be used with your back to the Sun with the sun’s rays passing over your shoulder through the pinhole. Never look through the pinhole at the Sun. Once the Sun is entirely eclipsed, however, its bright surface is hidden from view and it might be safe to look directly at the totally eclipsed Sun without any filters, but do this only for a second or two!
