1. BELL WORK! Make sure your name is on your homework.
Put your homework in the black tray on the teacher’s lab table.
Quietly review the steps of the scientific method…in order…memorize it!

SPI 0807.Inq.4
I can use evidence to draw a conclusion.
SPI 0807.Inq.5
I can identify bias or experimental error.

3. The Scientific Method
Make an Observation State the Problem or Ask a Question Gather Information and Research Form a Hypothesis Test the Hypothesis Analyze Data Write a Conclusion Communicate the Results

4. Show what you know…
What skill is a scientist using when she listens to the sounds that whales make?
Making observations
Drawing conclusions
Making a hypothesis
Interpreting data

5. Show what you know…
Which question would be the best scientific question for an experiment?
Who made the first microscope?
How many giraffes live in Africa?
Does the amount of salt in water affect the temperature at which it boils?
How long ago did dinosaurs live on the Earth?

6. Show what you know… In science, an educated guess is called a/an
Conclusion
Hypothesis
Observation
Question

7. Show what you know…
When you decide whether or not the data supports the original hypothesis, you are
Making Observations
Asking Questions
Forming a Hypothesis
Drawing Conclusions

8. Let’s compete!!! Who knows the steps…in order?
Each group needs a baggie of the steps of the scientific method.
Each member of your group will race to put the steps in order…top to bottom.
Use the timer to see who puts them in order the fastest.
Each member will get one practice round and then one timed round.
The winner is the person who puts the cards in order the fastest on the timed round.

9. Using the Scientific Method (Pg. 15)
Step 1: Make an Observation Example…
Identify the color.
See if it has a smell.
Feel it.

10. Using the Scientific Method (Pg. 15)
Step 2: Ask a Question or State the Problem Example…
How much water will it absorb?
Does candy make me hyper?

11. Using the Scientific Method (Pg. 15)
Step 3: Gather Information and Research Example…
Google it.
Ask around or interview someone.

12. Using the Scientific Method (Pg. 15)
Step 4: Form a Hypothesis Example…
Write an If-Then statement.
If I eat candy, then I will get hyper.

13. Using the Scientific Method (Pg. 15)
Step 5: Test Your Hypothesis Example…
Have a step-by-step procedure.
Only test one variable at a time.

14. Using the Scientific Method (Pg. 15)
Step 6: Analyze the Data Example…
Create a bar graph.

15. Using the Scientific Method (Pg. 15)
Step 7: Write a Conclusion Example…
Explain if your hypothesis was right or wrong.
Include your data in sentences.

16. Using the Scientific Method (Pg. 15)
Step 8: Communicate the Results Example…
Answer the question from the experiment.
This should be one good sentence.

17. There are ducks everywhere!
Make an Observation
There are ducks everywhere!

18. How can we make a good duck call?
Ask a Question
How can we make a good duck call?

19. Gather Information and Research
KEEP IT SHORT Keep your notes short. All too often I hear callers who are imitating a laughing Jackass. When ducks call, they call using distinct notes. They may be slightly attached, but in truth, keeping the notes detached sounds far more realistic at a distance, where the ducks are located. Maurice Eason, one of the best callers of ducks I’ve ever heard, calls in a manner that up close seems contrary to every championship caller any of us have ever heard. Save for his feed call, all the rest have detached notes. Eason calls it “sharp calling,” and that’s a fair assessment. The point is that by slightly detaching the notes one from the other, the calling sounds like the real thing where the ducks are located. This is not to say that calls should be choppy, but rather that each note of the descending calls should be slightly separated from the preceding note rather than run together, which might appeal to a calling-contest judge, but probably not the ducks.

20. Form a Hypothesis
If I create a duck call using long cuts instead of short ones, then the duck call will produce a higher pitch sound.

21. Test Your Hypothesis
You will make two duck calls all by yourself.
Follow the procedure very carefully.
Complete the handout.
Be sure to clean up your mess. The group boxes are not trash cans.
