1. 15 Lab: Paper Planes-experimental Reminders: September 15 Warm - Up:
Identify IV & DV
Today’s Agenda:
1. Identify IV & DV (experimental plane)
2. Write Problem Statement & Hypothesis
2. Collect data-experimental plane
Homework:
write lab report (due Friday, 9/19-test grade)
Reminders:

2. 21. If we increase the length of the pendulum, the number of swings will decrease.
IV = ____________________
DV = ___________________

3. 22. Factors that are kept the same in an
experiment are referred to as
__________________________.
(control, hypothesis, constants)
The experiment that lacks the
independent variable is called the
___________.
(conclusion, control, reserach)

4. Paper Planes

5. Problem:
How do I create a paper airplane that flies further than the control paper airplane?

6. Hypothesis:
If I change the ________________________, then the plane will travel further.

7. Experiment:
Materials:
2 pieces of copy paper
meterstick
colored pencils
__________

8. Experiment: Procedures:
-write the step-by-step instructions to make control plane and test it.
-write the step-by-step instructions to make experimental plane and test it.

9. Experiment (identify variables):
Independent variable: ___________________
Dependent variable: ____________________
Constants: size of the paper, type of paper, force used to launch plane, starting point, angle of release
Control: airplane with no modifications/changes

10. Observations: Copy data from both data tables.
Graph data using a line graph:
- put 10 trials on x-axis
- put distance (m) on y-axis
-use different colors for control and experimental plane
-make a key for control and experimental plane
Analyze/study your data.

11. Conclusion: (1-2 paragraphs)
--Restate your problem.
--Was your hypothesis supported or rejected by your data?
--Use you data to support/explain what you learned.
--could you of done anything better?
--did you make any mistakes coolecting you data?

12. DUE: Friday, September 19
(test grade)
