Bacteria Review

Today we went over and had time to finish the Bacterial Colonies Lab Report (one each - booklet with chart filled in and questions #1-4 answered). This should have been handed in during class.

Then we began reviewing bacteria information for our Bacteria and Virus Test, and we ended with the Bacteria Quiz.

Homework:

• Bacteria and Virus Test - Tues., Dec.2
• Bacteria (pamphlet) Project - due Thurs., Dec.4

Bacteria Review and Project

Today we went over our second bacterial review sheet. We also looked at the bacteria growing on our petri dishes. (Remember we collected it from different places in the school?) Lastly we went to the library to do research on the bacterial disease each of us chose from last class for our bacteria (pamphlet) project.

Click here for the bacteria project criteria sheet or rubric (how it will be marked).

Homework:

• Bacterial Colonies Lab Report- due Wed. (Nov.26)
• Bacteria Quiz Wed. (Nov.26)
• Bacteria and Virus Test - Tues., Dec.2
• Bacteria project - due Thurs., Dec.4

For the Bacteria Quiz you should know the information contained on the 1st bacteria review sheet, the 2nd bacteria review sheet, as well as the video notes we took. (To view one of these, click on it.)

Bacteria and Disease

This class we learned about some diseases that bacteria cause, we learned how bacteria cause disease, and what can prevent, control and cure bacterial diseases.

Homework:

• Bacteria Quiz on Wed., Nov. 26
• Virus and Bacteria Test on Tues, Dec. 2
• choose one of the following diseases for Monday, Nov.24:

Diphtheria

Tuberculosis

Typhoid Fever

Tetanus

Hansen Disease

Syphilis

Cholera

We will start a small bacteria research project on Monday. The criteria and rubrics will be given then. It will be due Fri., Nov. 28

Importance of Monerans

Last class we went over the bacteria review sheet, which included information about:

• the parts of bacteria
• the 4 phyla of bacteria
• how bacteria move
• how gram staining can help us tell the difference between bacteria (type of cell membrane) so doctors can prescribe the best antibiotics
• the different ways bacteria get food (types of autotrophs and heterotrophs)
• the different ways bacteria use the food and convert it into energy (with oxygen= obligate aerobes, without oxygen= obligate anaerobes, when either is fine=facultative anaerobes)

We also learned that bacteria are essential for life. We learned many different ways bacteria are important.

Homework:

• Virus Project due next class (Thurs., Nov.20)
• made a diagram for each of the three ways bacteria are important for our environment: draw and colour and label diagrams with 4 steps each due Thurs., Nov. 20
• bacteria quiz in two classes (Mon., Nov. 24)

Bacterial Cultures

Today we reviewed how bacteria reproduce and then we began an experiment to get samples and grow bacterial colonies from different locations in the school.

Homework: Rewiew Worksheet #1, 4, 5

Bacteria

Today we watched a video about Bacteria and filled in some notes about them. Then we recorded a few characteristics for each phylum (group) of Bacteria in a chart. We looked at our Virus quiz marks and finished by doing an in-class assignment of finding definitions for the following words found in Ch. 17-2:

1. phototrophic autotrophs
2. chemotrophic autotrophs
3. chemotrophic heterotrophs
4. phototrophic heterotrophs
5. obligate aerobes
6. obligate anaerobes
7. facultative anaerobes
8. binary fission
9. conjugation
10. endospore
11. symbiosis
12. saprophytes
13. nitrogen fixation

Homework: Read Sec. 17-2 (p. 363-372) and do questions # 3-5

Virus Quiz & New Section: Bacteria

Today we reviewed about how viruses affect human health and had a quiz.

Homework:

• Read Section 17-2 and do questions #1 & 2
• Virus Project choose and research a virus that infects humans, build a model of it and make a fact sheet/card - due Thursday, Nov. 20

Make sure you get a project criteria page from Miss Stevenson and hand it in with your project so that you don't lose a mark.

Viruses and Disease

Today we watched a video about our body's internal defences against viruses.
The following are the answers for the fill in the blank notes:

1. debris, irritates
2. increased blood flow
3. swollen glands, neck
4. lymphatic system
5. white
6. 1-protects blood from invaders, 2-removes useless or harmful cells, 3-is a "breaker's yard" for old red blood cells (i.e. it takes them apart, parts that are still good can be re-used)
7. white
8. lymphocytes
9. antibodies
10. outer coat
11. memory

We also got a review sheet to help us study for the Virus Quiz.

Homework:

• review sheet #9-12 due next class (Fri.)
• Virus Quiz Friday (Nov. 7) will cover class notes, video notes, review sheet, and textbook homework

Viruses

Today received a list of learning outcomes for this unit: microbiology. Then, we reviewed the two ways viruses infect a cell: lytic and lysogenic infection, and finished off our lesson with Level 4 (dangerous) viruses.

Homework:

• Make 2 diagrams (including pictures and sentences) to clearly show and describe the life cycle for each of the 2 types of viral infection. Make sure to include an even number of cells being burst at the end of the lysogenic virus life cycle.
