    Extension: Map of Our Yard or Block

    Walk your yard, block, or nearest park and note every land and water feature: a slope, a low muddy spot, a puddle that always forms, a creek, a storm drain, a big tree. Back inside, your child draws a map from above with a key and a compass rose, then marks where rainwater would flow with arrows (downhill, like the pan).
