Paper Airplane Lab

2. What we will do today… We will review the three types of variables
We will review how to write a research question and a hypothesis
We will review the parts of the scientific method
We will begin writing the paper airplane lab

3. How we will do it… Reading, writing, talking Cutting and gluing
Individual and small groups
Take notes

4. Three types of variables
Manipulated: The thing you change on purpose
Responding: The thing you hope is going to change, and you are measuring it.
Controlled: The things you keep the same (AKA everything else in the experiment)

5. Research Questions Always start with the words “How do” or “How does”
Then state the manipulated variable.
Followed by the word “affect” (or “affects”).
Then state the responding variable.
Finally, put a question mark.

6. Writing Hypotheses Start with the words “If the”.
Write the manipulated variable.
Add the type of change you’re choosing (increasing, decreasing, etc.)
Write the words “then the”.
Follow them with your responding variable.
Add the type of change you’re expecting (increasing, decreasing, etc.)
Write the word “because”.
Then write the science based reason you think it will happen.

7. Weight of a Paper Airplane How Far a Paper Airplane Flies
Title:
Weight of a Paper Airplane
and
How Far a Paper Airplane Flies

8. Research Question:
How does the weight of a paper airplane affect how far the paper airplane flies?

9. Variables: MV: weight of the paper airplane
RV: how far the paper airplane flies
CV: airplane design, type of paper, same place

10. Hypothesis
If the weight of the paper airplane increases, then how far a paper airplane flies will decrease, because heavier objects won’t fly as far as lighter objects.

11. Materials: Paper airplane
Three paper clips (all the same size and kind)
Meter stick or measuring tape
Masking tape

12. Procedures:
Stand with your toes just to the line of masking tape. With your hand at the side of your head, throw the plane.
Leave the plane in the position it lands in.
Measure how far the plane traveled using the meter stick. Measure from the masking tape to the farthest end of the plane.
Record measurement in centimeters.
Add a paper clip to the tail end of the plane.
Repeat steps 1-4.
Add a second paper clip to the tail end of the plane. Repeat steps 1-4.
Add a third paper clip to the tail end of the plane. Repeat steps 1-4.
Repeat steps 1-10 two more times.

13. Drawing Draw a picture of how the experiment is set up:
In front of masking tape
Where you will throw the airplane from (right beside your ear)
How you will measure it
