1. Science Planner 3/22/17 WALT: investigate characteristics of Soil.
WU: A soil sample measures the following:
1. Sand = 3.5 cm Silt = 1.4 cm 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
