Teacher's field guide

What Students Need to Do: Students identify how runoff from a construction site can carry soil into a creek. They design a way to keep soil on site and test whether it works.
What Mastery Looks Like: Students compare runoff from their design with runoff from bare soil using the same slope and amount of water. They use the results to improve a plan that workers could maintain.
Common Misconceptions: Students may think sediment only makes a creek look muddy, not that it can harm organisms. They may place a barrier where water can flow around it.
How to Assess It: Exit ticket: A construction site slopes toward a creek. Sketch one way to keep soil out of runoff, label where water goes, and name one measurement that would show whether it works.

Lesson moves

Build two sloped soil trays, leave one bare and cover one with mulch, then pour equal water and compare sediment in jars.
Ask students to write where they would put a soil barrier on a site map and what might happen during heavy rain.
Give pairs site maps and three fix cards with prices; have them choose a plan under $100 and explain where water goes.
Walk the school grounds after rain, mark exposed soil near drains, and sketch one low-cost change for the grounds crew.
