"Do you like scavenger hunts? How do you tell if creek water is clean and healthy? Join Lucas and his sister as they act like scientists looking for certain kinds of bugs (aquatic macroinvertebrates) that can only survive in unpolluted waters. What will they find as they turn over rocks, pick up leaves and sort through the mud? Read along to find out if their creek gets a passing grade"--
