Study Notes
Evaluating Scientific Evidence
- Scientific evidence is data collected during an experiment.
- Data analysis determines if evidence supports the hypothesis or answers the question.
Example: Boiling Point Experiment
- Question: Which boils faster, salt water or fresh water?
- Hypothesis: Salt water has a higher boiling point than fresh water.
- Data: Temperature readings during heating of both types of water.
- Expected outcome: Salt water's boiling point should be higher than fresh water's, based on the hypothesis.
Data Analysis and Interpretation
- Data fitting the hypothesis: Verify that collected data aligns with the predicted outcome.
- Example: Fresh water boils at 212°F, salt water at 216°F. This data supports the hypothesis.
- Replicability: Consistent results are crucial; if the measurements vary significantly, there may be errors needing investigation.
Interpretation Steps
- Identifying the outcome: Determine if collected data agrees with the hypothesis or answers the question.
- Interpreting results: The data demonstrates salt water boils at a higher temperature than fresh water.
- Presentation: Summarizing the interpretation, e.g., displaying boiling points next to diagrams of the water.
