Rainy Day Puddle Paths

It rains. You go out anyway. The child follows a trickle of water with a stick and marks where it went.

This is the only sheet in the set that requires bad weather, which in the tropics is a scheduling gift rather than a problem. Water follows the ground's shape and children discover slope without the word ever being used.

Wellingtons and a change of clothes, obviously. The page includes the note to parents that makes this possible, because the single biggest obstacle is a parent who sent one uniform.

We follow up the next dry day by walking the same route and finding the marks. The water is gone and the evidence is not, which is close to the definition of geology and lands surprisingly well at four.
