Solar eclipse

Have you tried 'Why does the sun disappear?' This activity demonstrates what happens when the Moon hides the Sun. After carrying out this ELI, pupils can appreciate that the Sun and the Moon are of vastly different sizes even though, when they appear in
the sky together, they seem to be of comparable diameter. They can explain that a small object that is near the Earth can block out a much larger object that is much further away. Also, they can do simple calculations to work out the model Sun's diameter.
This is one of the activities in the category 'Earth in space'. Can you add any more ideas?
