2. How did the water wear away and drop off the gravel, sand, humus and clay? The sand.

3. What did you observe about the particles of sand, and gravel in the stream table? We saw all the gravel go down the stream that the water made and saw all the sand at the other end of the stream table.

4. What did you observe about the other particles of soil? That the soil stayed around the same spot it was before we poured the water.

5. What ws the length of your block of soil? 39 cm

Compare the lengths with the other teams in your room. Are the lengths the same?
Why or why not? The runoff is smaller. It is because it is only a small part of the streamtable.
