Features Lesson ModuleMaterials
- chalk – the rock
- 2 clear cups
- water
- 1 permanent marker

Question: Will still or moving water weather a rock faster?
Hypothesis: If a rock is placed in moving water then it will break down, or weather, faster.
Statement: Moving water weathers rocks faster.
Procedure Outline:
- Mark one cup “Moving”.
- Fill each cup halfway with water.
- Break one whole piece of chalk in half.
- Put a piece of the chalk into each cup.
- Pick up the cup marked “Moving” and shake and swirl it, be careful not to spill, for 2 minutes.
- Record your observations of both cups.
- Pick up the cup marked “Moving” and shake and swirl it again for 2 more minutes.
- Record your observations of both cups.
Be on the lookout for…
What happened to the chalk in the Moving cup?
Did anything happen to the chalk in the other cup?
When the water settled down in the Moving cup, did you notice anything at the bottom of the cup?
What do you think would happen if you continued to swirl the Moving cup?
Do you think rocks would weather, or break down, faster in a river or a pond?
Estimated Duration: 15 minutes
