Scientists study fossil clues and other shapes and patterns in the rock to learn about the past.
Create your own patterns in sand and mud and draw a picture of them.
Part 1 -
What settles to the bottom the fastest?
What takes the longest to settle?
Draw in your booklet how the sediment size changes from the bottom to the top of the jug.
Part 2 -
What has happened to the sand
Draw the sand pattern.
Main Message: Students should see that moving water influences how sediments accumulate and be able to imagine that this can be preserved in rocks.
Connections: Settling sediment is what buries and preserves fossils (activity 1).
