When you observe rocks in a stream or river, you often find they share common characteristics.The fast moving water moves rocks downstream. As the water slows down, the rocks slowly stop moving. Typically the largest rocks stop moving first while the smaller sized rocks continue moving until the water slows down even more.

 

Procedure:

Below are pictures of six different-sized particles. Imagine that you can put them in a large container filled with water and then shake the container vigorously. The particles are labeled A, B, C, D,  E and F. Look closely at each and determine the order you would arrange them in based on how they would settle out ... from bottom to top.

After completing the above activity, drag your mouse to check your answer.
