Science Planner 3/22/17 WALT: investigate characteristics of Soil. WU: A soil sample measures the following: 1. Sand = 3.5 cm 2. Silt = 1.4 cm 3. Clay = 0.2 cm Total amount of soil = 5.1 cm What percent of the total combined soil sample does each component represent? Sand = 68.6% Silt = 27.5% Clay = 3.9% CW: Assignment
