1. '''Someone from your team must go to your sample site and collect a new soil sample as you did in Lab 1.''' On the day of Lab 3, BEFORE lab begins, stop by the lab to pick up a plastic bag containing materials for collecting a new soil sample from your sampling site. This time your group will only need enough soil to fill half of a sterile, 15ml, orange capped, conical tube. Make sure you get the sample for THE SAME sampling site as your original sample. Again avoid the top few millimeters of surface soil and wear gloves to avoid contaminating the sample with bacteria from your skin. You probably won't need to use the corer; a disinfected metal spatula or even a spoon should work fine. | 1.
