To complete the investigation, each student group will need: 2 clear-plastic 300 mL (10 oz.) cups A soil sample (taken from your local area) A 250 mL (8 oz.) cup of water A stopwatch, or watch with second hand A plastic drinking straw To learn more about gravity, friction, and their effect on the settling of grains in water, visit the following web sites: " Stoke's Law " - Maine Maritime Academy This brief article explains the mathematical formula used to calculate how fast particles will settle in a liquid.
