PROCEDURE• Get enough plastic cups so there is one for each sample.• Label each cup with one type of soil.• Photograph each soil sample and write dot points on what it lookslike, feels like and its colour.• Fill each cup with its matching sample.• Fill each cup with 150ml of cold water.• Leave next to each other in a cupboard for an hour.• When the hour is up take them out of the cupboard at the same time.• Place one cloth over each up.• Prepare the measuring cup.• Turn over first cup and drain water into the measuring cups.• Measure and write down data.• Rinse measuring cup and repeat step for remaining three cups.• Once they’re all measured and data has been collected figure out thecup that drained the least amount of water.• The cup which drained the least water is the one that is most absorbent.
