What This Standard Means

What Students Need to Do

Students observe nearby soil and rocks for clues such as channels, sediment piles, exposed roots, and worn surfaces. They use those clues to explain how moving water or air caused changes over time.

What Mastery Looks Like

Students record clear observations and connect them to a cause. They explain that repeated wind or water movement can slowly wear rock, remove soil, and deposit material elsewhere.

Common Misconceptions

Students may think all changes happen during one storm or that wind cannot move soil. They may also confuse direct observations with guesses about what happened.

How to Assess It

Show a photo of soil below a downspout. Ask students to name two visible clues and explain how the changes likely happened over time.

Ways to Teach It

  1. Take a schoolyard walk with hand lenses and rulers, then sketch channels, sediment piles, exposed roots, and worn rock surfaces.

  2. Use the prompt, “What changed here, what caused it, and which two observations support your explanation?”

  3. Sort photo cards into water, wind, both, or unclear, then defend each choice with one visible clue.

  4. Inspect soil below a gutter downspout and beside a wall, then explain why the two spots look different.
