Pamela,
the activity from https://mysteryscience.com/sky/mystery-6/stars-daily-patterns/128
is a great way to introduce light pollution linked to the appearance of the stars when it is dark, not when it is day.
I’ve signed up for it – its a shame the archived readings are to other sites that you have to sign up for, and some of the features are locked unless you refer people.
“You need to refer five friends to view past mini-lessons – here’s the current one instead.”
