Answer:
Cut plastic bottles in half and fill with a variety of soils. You might consider using soil mixed with sand, soil mixed with rocks or gravel, soil mixed with wood chips, or soil mixed with clay. Arrange the plastic bottles on a slant, and pour water at the highest point. As the water trickles down, students collect the run-off in plastic cups. Have students examine the water and discuss how much of the soil ended up in the cups.
