Lab Report – Peer Review Process �Grade the lab reports of two other students in the class using the grading rubric. �Upload the graded rubrics to Black. Board at the end of class. �You are not graded on the quality of your draft today; the goal is to receive valuable feedback from your peers.

Diversity of Life Activity 3 – Bacteria in Soil (Completion)

Bacterial Colony �Visible cluster of bacteria growing on the surface of or within a solid medium, theoretically cultured from a single cell. Colonies

Counting is easy if your colonies look like these. More difficult if your colonies look like these (more likely!)

Colony Counting Technique �Place Petri dish on colony counting grid. �Work your way back and forth, row by row, to count colonies in each square.

�Sketch Petri dishes in Figure 3. 1, page 139. control rinse dirt control soap 1 soap 2 Fig 3. 1. Sketch of bacterial growth on individual group’s Petri dish 1 and 2 by treatment segment.

Treatment Type Table 3. 1 Petri Dish #1 Group # Con Dirty Petri Dish #2 Rinse Con Soap 1 Soap 2 1 2 3 4 5 6 �Record number of colonies from each segment of each of your group’s Petri dishes in Table 3. 1, page 139.

Diversity of Life – Activity 7 – Microscopic Fungi

�Fungal growth should look similar to bacterial growth. �So, count colonies using the same procedure as with bacteria.

�Place Petri dish on colony counting grid. �Work your way back and forth, row by row, to count the colonies in each grid square.
