Spot the Mistake
A. Statement of Problem
How will changing the height from where a ball is dropped (Inches) affect how high the ball bounces back up (Inches)?
It needs IV Levels: (24 inches, 18 inches, 12 inches)
Topic: Aviation/Aerodynamics
Materials:
How will the number of weights attached to a paper airplane affect the flight distance?
What is the format for the Statement of Problem?
How will changing the [IV] (IV Levels) affect the [DV] (units)?
There aren't any outliers.
J. Analysis and Interpretation of Data
What is the Max number of people on one EXPD team?
C. Variables
Controlled Variables: Gravitational pull of the Earth, Type of floor
Constants: Type of Bouncy Ball
The gravitational pull of the Earth is a constant, not a Controlled Variable.
Topic: Memory
How will the amount of time a person has to look at a pattern of colored dots affect how well they recount the pattern of colored dots?
What is the format for the Hypothesis?
As we change the [IV] (IV Levels), the [DV] will ____. BECAUSE ______.
We reject our hypothesis.
L. Conclusion
What can you bring into the testing room?
1 timepiece
1 Linear Measuring Device
1 Calculator
Writing Utensils
Required: 1 pair of safety glasses
M. Recommendations for future experiments
Practical Applications: Hanglider safety, the aerodynamics of rockets.
No Rational for Practical Applications
Topic: None
How will the type of art tool used to draw a picture affect someone's rating from 1-10?
What is required to finish Variables?
IV with levels and units
DV with units
2 Controlled variables
1 Constant.
- The paper was crinkled at the edges when we first received it.
F. Qualitative Observations (Procedure before)
How long do you have to finish an EXPD Test?
50 Minutes
J. Analysis and Interpretation of Data
Claim: There are no outliers
Evidence: No data point is too far away from another data point in the same IV Level resulting in no outliers.
Reasoning: There are no outliers because no data point is too far away from another data point in the same IV Level
Evidence shouldn't contain reasoning
Topic: Acids and Bases
Materials:
How will the amount of lemon juice added to milk affect the PH of the mixture?
How should you title your graph?
IV vs DV (X-axis vs Y-Axis)
The PH paper could have been in contact with particulates floating around in the air before we dipped it into the solution.
K. Possible Experimental Errors
What type of calculator can you bring to an EXPD Test?
Non-Programmable and Non-Graphing.
H. Graph
Title: Height of the ball on the second bounce (inches) vs. Initial drop height (24 in, 18 in, 12 in).
It should be reversed, being X-axis (IV) vs Y-axis (DV)
Topic: Chromatography
Materials:
How will the color of the Marker affect how far it spreads on a coffee filter when in contact with water?
What is required for Recommendations for Future Experimentation?
2 Practical Applications
2 Future Experiment Ideas
2 Improvements to the experiment
Mean vs. The height from where the rubber ball was dropped (in).
G. Quantitative Data - Raw & Condensed Data Tables
How much will be deducted if you don't clean up or don't use at least 2 materials?
.05 of your score.
