By the light of the moon

If anything bizarre happened last night, don't panic - it's just the full moon. Or at least that's what lunar urban legends suggest.

Let there be light, but not too much of it

How can light pollution be reduced?

At school we have a monitor to lead a class and a teacher to manage it; a prefect to lead the whole school and a principal to manage the institute.
