SCIENCE EXPLORATION OF EROSION

Think about the two different demonstrations that took place outside this week.


 * First,** explain __what we did__ in the first ditch. Tell about the __landforms you saw being formed__. Explain __how you knew what you were seeing__. (example: A valley was formed because a low place between the two mountains was formed.)


 * Next**, the second paragraph will tell about __what we did__ in the ditch at the top of the hill and __what you learned.__

You will be graded on whether you used all of the vocabulary words correctly and if you followed the directions to form two paragraphs with topic sentences and concluding sentences and had all required information.

Use the following vocabulary in 2 well written paragraphs. Be sure to include an explanation of how you know each of the things you learned. You may type it here or write on a separate sheet of notebook paper. You will have 2 days to work on it before turning it in.
 * erosion sediment meander canyon delta**
 * river basin deposition slope dam lake**

On Dirt Day,we saw how water can make __landforms__. Erosion carried away __sediment__ to make a __canyon__. The water made a __river__ with winding __meanders__ that carried __sediment__ to make a fan shaped __delta__. __Deposition__ is the process of __sediment__ going down the __river__ to make the __delta__.

In the ditch on top of the hill, we tried to make __dams__ to stop the river from flowing.We hoped the water would fill the __basin__ behind the dam to make a __lake__. But the __slope__ was too steep. I learned that making a dam is hard work to do.
