# Title:

Does size matter.

# By:

Tanner, Brock, Christian, and Jack.

# Hypothesis:

I don't think that bigger stones will change how much dirt gets in the water?

# Question:

Would there be a difference if we used bigger stones?

# Materials:

1. Stones

2. Stream Table

3. Water

4. Layers of Soil

5. Timer

# Setup:

Our first setup was with bigger rocks/stones in the mixture of sand and clay.

Our second setup had an equal amount of sand, clay, and gravel.

# Data/Results:

We were measuring how long it took for the water to reach the hole with larger stones in the way using seconds.  The measurement reached 38.24 seconds

# Conclusion

Yes, size does matter because it took longer for the water to get to the hole with larger rocks. We know that because with big rocks, it took 38.24 seconds, and with small rocks it took 47.91 seconds to go in the bowl. It took longer because the bigger rocks stopped more of the water.
