Back to our 'Rolling a Ball' experiment
-Follow Inquiry & Patterns Slides (begin at slide #44)
Time a Rolling Ball
Record times:
At your lab table, answer:
- Why is there a range of times recorded for this single event?
- What is the “true” time of the roll?
- How do we intelligently deal with this?
Uncertainty: while we record a single value for our measurement, we acknowledge that more measurements will not be exactly the same but likely always be within a certain range of the recorded value.
Rules of Uncertainty:
– Last significant figure is uncertain
– Uncertainty is 1 significant figure
– Record your measurement to match the uncertainty.
Averaging:
Uncertainty is =Range/2

Focus Question
What are the requirements of a Standard Lab Report?
Connecting Science with our Process...
What do we expect a lab report to look like?
Parts of a Lab Report:
1. Focused Research Question
2. Hypothesis
3. Design of Experiment
4. Data
5. Data Analysis to find the Pattern
6. Build a Consensus
7. Evidence-based Conclusion
The Phenomenon: Pendulum
What are questions we can ask about this?
What is included in the system we will investigate? What is outside the system?
