LESSON 6

CHAPTER 10

Setting up the research project

Entry ticket

• Go to KWIZL and do the entry ticket assignment

ET_CH10_LSN6_Adaptive immunity

• You have 10 minutes to complete
• You have 7 minutes to peer review the work of another.
• Everyone is done in 18 minutes.
• Quick review

Lab-project bacterial culture:

• In pairs (not 1 or 3)
• One lab report handed per pair in :

Monday 31st of October for feedback

Monday 21nd of November definitively

• Grade counts 2x.

Google classroom

NOW READ the following document on the google classroom

YR3_PROJECT_CH10

You do this silently!

Instructions for culturing

1. one bag of materials PER PERSON
2. one petri dish to be kept cold (fridge; 4-7 *C)
3. one petri dish to be kept at room temperature (around 21 *C)
4. divide each petri dish in two halves: A and B
5. write warm on one petri dish and cold on the other
6. when writing: WRITE ON THE BOTTOM (not on the lid)
7. choose two locations to swab: A and B
8. collect the swabs and use the q-tips to infect the dishes
9. collect pictures and data for at least two weeks

When swabbing...

1. keep the dishes closed as long as you can.
2. move the q-tip over the object that you want to sample
3. open the lid and gently WITHOUT PRESSURE stroke the q-tip over the agar surface (otherwise the agar will tear)
4. remember: A and B are separate locations!
5. quickly close the lid
6. when swabbing the agar, keep the plate up-side-down

TIPS

- Don't wait too long with swabbing: the quality of the agar deteriorates 

- NEVER open the lid when bacterial cultures have appeared.

About scientific research

Research question

- indicates a link between two factors (

- independent and dependent variable

- is specific and manageable

Hypothesis

- predicted outcome

- includes link from research question

- is ALWAYS explained

- if.... then.... because

The independent variable 

More than one group

- experimental group

- more experimental groups are optional

- control group

One difference: the independent variable

- The variable factor is manipulated by the researchers 

- belongs on the x-axis of graphs

Look at the image:

What is the main purpose for including a control group in your experiment?

1. because that increases the group size
2. because the experiment can be controlled better
3. because the data of the experimental group needs to be compared to a normal setting
4. because the data of the control group will influence the data from the experimental group

What is the variable in your lab project that is manipulated by you?

1. temperature
2. locations

What now?

1. form pairs
2. fill out the form on the classroom to let me know who your lab partner is
3. find a seat next to each other and re-read the following parts 1, 2 and 3 of the project introduction (YR3_PROJECT_CH10)
4. You also find the YR3_PROJECT_CH10 document in the 'labreport: hand in your first draft here'-assignment. Divide roles in this document in part 2 of the document. 
5. Write down your research question and hypothesis in part 3 of the document. 
6. Discuss and determine your locations (A and B)
7. Start writing Chapters 1 and 2 of the lab report in the 'first draft project CH10' document
8. Are there any remaining questions?

What is to come?

17th October: lesson 7 (immunization and blood groups)

24th October: Autumn break

31st October: HAND IN first draft lab report & lesson 8 (diseases, substance abuse)

7th November: start test week 1
