Objective: To classify soil samples by particle size
Purpose: To see how a mixture of material types affects soil properties

Procedure #1
•Look at your soil sample and make observations
•Observe color type and size of particles
•Estimate the composition of your sample based on particle size
•Use the triangle diagram to classify your soil

Procedure #2
use the Flow chart to ID your soil
Procedure #3
•Put the soil into your water bottle. You only need to fill about ½ way if you have lots of soil.
•Put 1 level teaspoon of Calgon into the bottle and enjoy the smell (Fiona)
•Fill until the bottle is about ¾ full
•Place the lid on tightly
•Shake vigorously for 2-3 minutes
•Observe your bottle after 2 minutes and again at 5 minutes
•Place bottle aside to allow particles to settle by particle size
