    Work in groups on these problems. You should try to answer the questions without referring to your textbook. If you get stuck, try asking another group for help.

    1. Did you inoculate your broth, slant, and plate properly? How do you know? (0.5)

    2. What is aseptic technique and why do we use it? (1)

    3. You inoculate a plate from a plate, you see no growth the next day. You know the plate had live bacteria on it. What went wrong? (1)

    4. What is a Durham tube and what do we use it for? (1)

    5. What is the difference between a slant and a slant/deep? (0.5) NOTE: do not just define the two terms, write an actual sentence describing the difference.

    6. Which plate, the one inoculated from a broth or the one from a plate, would you expect to see more bacteria on? Why? (1)
