How did they calculate the speed of Ryan Matthews?

2. What does a motion map show?
What does a distance/time graph show or represent?

3. Table of Contents Update
2/22(Blue) Speed Lab – Rough Draft Page 35 2/22(Blue) Speed Lab – Data Table Page 36

4. Data Analysis Paragraph 1:
State the purpose of the investigation (The purpose of this investigation was to…)
What was your hypothesis (It was proposed that…, It was hypothesized that)
Present results/data: The results of the experiment showed…
This should include the quantitative as well as qualitative data from your experiment: Report averages only
What do the results of the experiment indicate? (What does your data mean?)
Paragraph 2:
What were the expected results? (Refer to prior research)
If the results were not as expected, explain possible reasons for the results obtained
Explain possible sources of error in the experiment ( at least 3)
Explain how the experiment could be modified (How could the procedures be improved to reduce experimental error? How could you eliminate unwanted variables?)
*If the results ARE as expected, explain how the data is reliable/valid
(Reliability refers to the consistency of results and validity refers to the experimental design- the experiment measured what it was supposed to measure.)

6. Problem: How fast is the average teenager? Page 35
Hypothesis: If….then…because (refer prior research)
