WATER PRESURE

By:Gavin, Brea, Michelle, Breanna.

QUESTION:

What would happen if we changed the water pressure?

HYPOTHESIS:

The soil will weather faster because it has a great force.

MATERIALS:

* 2 liters

* 2 medium cups

* Clay and gravel

SET UP:

We are going to measure the difference of the water pressure between two different cups.

Step 1: Pour water in the cups.

Step 2: Place the cups on 2 trays.

Step 3: Observe the water pressure.

Step 4: Record the results.

We are going to keep the water and soil the same.

CONCLUSION:

The cup with the 3 big holes had more water pressure than the cup with 3 little holes because more water went through the cup.
