Miss Zelle's Science Class Tests Soil

Students tested which soil would hold the most water. 

They wrote a hypothesis
If I pour 200 milliliters (mL) of water into a cup of soil and sand, then I think _____ will hold the most water because _____________________. 

Materials:

200 ml of water     1 cup of soil     1 cup of sand

Measuring cup

Procedure:

1.Slowly pour the water into the sand.  Stop when the water begins to puddle on top. 

2.Calculate the amount of water the sand absorbed. 

3.Slowly pour the water into the potting soil.  Stop when the water begins to puddle on top.

4.Calculate the amount of water the potting soil absorbed. 

Then Students drew conclusions by answering the following questions as a group:

1.Infer where the water that you poured into the potting soil and sand went

2.What do the results of the investigation tell about how the size of particles and spaces in between particles compare in the sand and soil?
