Solar eclipse

Last Friday, many people were watching the solar eclipse. Perhaps it's a good time to try the ELI 'Why does the Sun disappear?' This activity demonstrates how a small object, which is near, can block out the view of a much larger one that is further away. Do you think the Sun and the Moon often appear to be the same size in the sky? In fact, they are not the same size at all and yet the Moon can block out the Sun completely, so that it goes quite dark. This is called a total eclipse of the Sun (or a solar eclipse).

The image above is from the NASA website. The photo below shows the recent eclipse as viewed through a colander!
You could also try the ELI 'Eclipse the lollipop' which models eclipses of the Moon and the Sun with a ball, lollipops and a bright light.
