Airplane

Airplane

• We have been discussing the Scientific Method.
  It is a way of figuring things out.
• Now we will focus on the Experiment or Test
  part of the Scientific Method.

2

• Make up a funny sentence using the following
  words
• Manipulated Variable
• Responding Variable
• Controls
• Experimental Control
• If. then. .because.
• Record data
• Repeated trials
• Pizza

3

• -If you throw your airplane when youre not
  supposed to, it will be taken away.
• -Fold your airplane.
• -When youre done, please wait patiently.
• -Follow instructions on where and when to throw
  your plane.

4

• Manipulated Variable- what will you change.
• Responding Variable- whats measured that changes
  due to your manipulation.
• Controlled variablessssssssssss everything
  else that is kept the same.
• Experimental control what we compare to to see
  that something different happened.

5
trials Distance??????
1 14 m
2 13 m
3 Etc. . . . . . .

40

• Responding Variable
• What will you measure?
• Distance, height, speed, spins, ???
• Make a graph to record your responding variable
  each time you throw.

6
Go ahead and throw under control.If you get out
of control you will be asked to stop.
7
Average your throws

• Add up the measurements.
• Divide by the number of trials you threw.
• What is the average?

8

• Manipulated Variable- what will you change.
• Responding Variable- whats measured that changes
  due to your manipulation.
• Controlled variablessssssssssss everything
  else that is kept the same.
• Experimental control what we compare to to see
  that something different happened.

9
Lab write-up

• You will include the following slides in a lab
  write-up
• Due __?____

10

• 1. Question
• Whats the problem (question) we want to figure
  out? Include both your manipulated and responding
  variable.
• --What is the effect of the manipulated variable
  on the responding variable?

11

• 2. Hypothesis
• If _manipulated variable___increases/decreases
  then__responding variable__increases/decreases
  because ____________________.

12
3. Experiment

• i. What will your experiment be?
• ii. What materials do you need? Make a list and
  explain.
• iii. Draw a picture.
• iv. Describe your procedure so a 3rd grader
  could repeat your experiment.

13
iv. Include the below in your procedure.

• State you need to measure and record your data in
  your procedure.
• State you need to repeat the ENTIRE experiment 40
  times. Or 50, or 60. . . .
• Calculate and average your 40 trials before
  manipulation and after.

14

• The Experimental Control is what we will
  compare to. What will it be in this activity?
• (before modification)

15

• Copy the following chart What are your answers?

Manipulated Variable (What youre going to change) Responding Variable (What gets changed. You measure it) Control Variables. Constants (They remain the same) Experimental control (What youre comparing to)
1.
16
4. Data, table, (copy onto paper)
Trials Responding variable measured before modification Responding variable measured after modification
1. 2. 3. Copy from old chart Fill in as you do your experiment
4. 5. 6.
17
4. More Data, chart

• This graph shows the effect of the manipulated
  variable (flaps) on the responding variable
  (distance).

18
4. More Data, table

• This graph shows the distance thrown before and
  after manipulation.

19
5. Analysis

• Average distance before manipulation
• 14 meters
• Vs.
• Average distance after manipulation
• 16 meters
• 16 m 14 m 2 m diff
• The airplane went on average 2 meters further
  with tail flaps than without tail flaps.

20
5. Still More Analysis

• Write a paragraph explaining your analysis.
  Include your averages and what your chart
  suggests.
• Dont mention a conclusion yet. Dont mention
  your hypothesis yet. Just mention what your
  averages and chart tell you.

21
6. Conclusion

• i. Was your hypothesis supported or not
  supported based on your data?
• Restate your hypothesis.
• Include supporting data from your data table.
• Explain how these data support your conclusion.
• ii. How does this investigation help YOU to
  understand the natural world?
• iii. What could you do next time?

22
Computer work

• Type lab info from notes in a logical order.
• Create the 5 sections
• Purpose
• Procedure
• Data
• Analysis
• Conclusion
• You may write in paragraph or list form.
• Once done, check rubric and make sure your report
  includes all requirements.

23
Double checkDo you have a title page?

• Airplane flaps experiment
• John Smith
• 9/19/07
• Report prepared for
• Mr. Penner
• Biology

24
Formatting

• Purpose
• Question What is the . . . .
• Hypothesis If wing flaps are increased . . . . .
  because . . .
• Procedure
• My experiment was to . . . .(summary)
• Materials 1. paper for making the planes
• 2. . . .
• Procedure 1. Acquire a piece of paper

25
Section 2

• It is best to write down your procedure in the
  following format rather than what the rubric
  says
• i. What will your experiment be?
• ii. What materials do you need? Make a list and
  explain.
• iii. Describe your procedure so a 3rd grader
  could repeat your experiment.
• iv. Draw a picture.

26

• You dont have to follow the rubric, BUT when
  youre done make sure that whats required in the
  rubric is in your procedure section.
• So, in your procedure, do you have
• manipulated variable stated
• control variable stated
• logical steps
• etc.

27
Other

• If you cant easily locate some of the items on
  the rubric then
• Find them yourself and write what it is
• ie. ?(manipulated variable)
• Or write the requirment and then write what the
  answer is.
• Ie. The airplane flap is the manipulated
  variable

28
Do not use
Instead use
The airplane 3rd The distance The throws Etc.

• It
• Then
• This
• Them

29
Tables

• How do you make them?
• First go to insert, second insert text box
• Create text box on screen
• Click on table and insert table

Computers tomorrow

• Corrected project due Monday in class.
