Can you find the ten secret sites by tracking changes in sunlight?

Here's a clue from one of the secret sites:

There are ten Mystery Classes all waiting to be found.
The shadows of our class are shown on the ground.
Long shadows on our sundial and it's just before noon.
But the changing of seasons brings us short shadows soon.
So first track the sun and then follow the clues.
Take the challenge to find us. You've got nothing to lose.
