LESSON 6
CHAPTER 10

Setting up the research project

Slide 1 - Slide

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


timer
18:00

Slide 2 - Slide

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.

Slide 3 - Slide

Google classroom
NOW READ the following document on the google classroom

YR3_PROJECT_CH10

You do this silently!

Slide 4 - Slide

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

Slide 5 - Slide

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.

Slide 6 - Slide

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


Slide 7 - Slide

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


Slide 8 - Slide

Look at the image:

What is the main purpose for including a control group in your experiment?
A
because that increases the group size
B
because the experiment can be controlled better
C
because the data of the experimental group needs to be compared to a normal setting
D
because the data of the control group will influence the data from the experimental group

Slide 9 - Quiz

What is the variable in your lab project that is manipulated by you?
A
temperature
B
locations

Slide 10 - Quiz

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?

Slide 11 - Slide

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
