LEARNING TARGETS

I can write an analysis paragraph that thoroughly addresses validity and reliability.I can research and share the major characteristics of a bacterial disease.

LAB REPORT PEER CHECK

Complete the check list for the person sitting next to you.In another color, make changes to your lab report based on this feed back.

LAB ANALYSIS Lab reports have a conclusion section (CLEVR!) and analysis section, including:

How do you know data was RELIABLE?What could have made it more reliable?

How do you know data was VALID?What could have made it more valid?

VALID VS. RELIABLE

Reliable = always same results.Friend who is reliable – always there.Increase Reliability – Repeat trials, Have someone else carry out the procedure and get the same results, use accurate equipment.

Valid = your conclusion the only possible conclusion; followed scientific method.Increase Validity – all about Variables. (Controlling variables, only one Manipulated Variable).

LAST STEP!

Add an analysis paragraph to your lab report.

How do you know data was RELIABLE?What could have made it more reliable? – at least 2 ways

How do you know data was VALID?What could have made it more valid? – at least 2 ways

Labs have already been stamped! They will be collected and graded for real on test day (Thursday 9/24 and Friday 9/25)

DISEASE JIGSAW Choose a disease in your group of 4:

Cholera, Bacterial Meningitis, Salmonella (food poisoning), Tuberculosis

Make an informational handout that you might find in a Doctor’s office about your disease. What bacteria causes it? What does the bacteria look like? How does the bacteria gets its energy? How is the bacteria treated (killed)? Is the treatment effective?

How do people come in contact with the bacteria? What are the symptoms? How is the disease prevented?

RESOURCES AND REQUIREMENTS

Use www.cdc.gov, www.who.int, www.webmd.com, or other reputable sites (not Wikipedia)Record sources on the back.Must be at least 8.5 x 11Use color and separate info. into boxesWrite in pen and be neat! Can be typed or hand-written.

Due Next Time!

LAST SLIDE 9/14-15

MORNING ROUTINE

What is your morning routine?

Start with step 1 – wake up.

Last step is sit down in 1st / 4th period.

Summarize each step in less than 10 words.

Make an ordered, numbered list in your lab notebook.

MY SAMPLE MORNING ROUTINE

1. Wake up.

2. Hit snooze button.

3. Wake up again.

4. Have coffee.

5. Feed animals.

6. Do hair and make up.

7. Get dressed.

8. Eat breakfast.

9. Pack lunches.

10. Pack school bag.

11. Drive to work.

Wake

up

Hit

Snooze

Wake up again

WHAT HAPPENS IF SOMETHING DISRUPTS YOUR MORNING ROUTINE? Start with your first 10 steps.

Add in at least two possible interruptions, and follow the interruptions to their conclusion.

SYSTEMATIC AND NON-LINEAR Your morning routine is systematic. Systematic = having a method or plan

Your morning routine is also non-linear. Non-linear = doesn’t necessary follow steps in a straight line.

STORY TIME!

Ignaz Semmelweis was…

He first discovered that something microscopic caused disease (called them cadaver particles)

His methods were systematic and non-linear.

SEMMELWEIS’ PROCESS

Conduct investigation Generate testable question Propose explanation Make observations Access prior knowledge

Design investigation Consult other scientists Conduct new investigation Consider alternate explanations

• As I read, listen for these steps:

SEMMELWEIS’ PROCESS

Make a flowchart in your lab book of Semmelweis’ process.

Then, explain why is it both systematic and non-linear, using events/evidence from the article. (3-4 sentences)

SEMMELWEIS PRE-READING Preview Read 1st sentence or two of each paragraph. Predict – what is the paragraph about? Repeat for every paragraph from pgs. 29-31.

When complete, discuss with table group – what is the entire reading about?

Try not to read every word in every paragraph yet. (That’s like cheating).

SEMMELWEIS READING

In lab notebook, make a T-Chart with “Systematic” on one side and “Non-Linear” on the other side.

Read the tan sections on pgs. 29 – 31.

Log anything systematic Semmelweis does.

Log any non-linear steps on the path to acceptance of germ theory.
