Preparation for FFA Competition: How to Grade Sediment Pads

How to Grade Sediment Pads

Students - You will have 9 minutes to score five sediment pads based on the degree of sediment. The sediment pads are scored according to the United States Department of Agriculture Sediment Standards for Milk and Milk Products. Each sediment pad represents the sediment from one pint of milk. See Scoring Guide for how sediment pads are graded.
Coaches - Your students need to be able to grade the quality of milk by evaluating a number of sediment pads. Here are some instructions to follow to set up this lab.
