Study Notes
Scientific Evidence
- Scientific evidence refers to the data collected during an experiment.
- The purpose of scientific evidence is to answer the research question and support or reject the hypothesis.
Analyzing Scientific Evidence
- To analyze the data, you need to determine if it answers your question and supports your hypothesis.
- Ask yourself what you would expect to see if your hypothesis is true.
- Look for the point where the data begins to boil in each type of water.
- Compare the boiling points of salt water and fresh water to determine if the data fits the hypothesis.
Does the Data Fit?
- If the data fits the hypothesis, the boiling point of salt water should be higher than that of fresh water.
- Replicating the result is crucial; if the data varies each time, it may indicate an error in the experiment.
Interpreting the Data
- Interpreting the data means explaining what the data says.
- Interpretation occurs when checking if the data fits the hypothesis.
- The interpretation of the data should clearly state the findings, e.g., the boiling point of salt water is higher than that of fresh water.
- Visual aids like charts or diagrams can be used to illustrate the interpretation.
