Study Notes
Testable Questions
- A testable question can be answered through hands-on investigation.
- It involves manipulating one variable to observe the effect on another.
General Interest Science vs. Testable Questions
- General interest science questions are broader, while testable questions are specific and focus on causal relationships.
Creating a Good Hypothesis
- Formulating a hypothesis should be based on existing research or personal knowledge.
- A hypothesis should be clear and measurable, avoiding ambiguous language such as "may."
Observations vs. Inferences
- Observations are factual data collected through senses.
- Inferences are interpretations or conclusions drawn from observations.
Qualitative vs. Quantitative Observations
- Qualitative observations are descriptive and derived from sensory data.
- Quantitative observations involve numerical data obtained through instruments (e.g., rulers).
Writing Effective Hypotheses
- A hypothesis should be definitive, stating what is being tested and predicting an outcome.
- Effective hypotheses must be measurable to allow for experimentation.
Variables in Experiments
- Only one variable should be changed at a time in an experiment to isolate effects.
Importance of Sufficient Sample Sizes
- Utilizing multiple subjects in both control and experimental groups enhances the accuracy of results.
- Larger sample sizes provide a better basis for conclusions.
Data Presentation Methods
- Graphical data can be presented using various methods, including defining questions, forming hypotheses, gathering resources, and planning data collection.
Reasons for Unexpected Data Results
- Discrepancies between data and hypotheses could arise from an incorrect hypothesis or flawed data.
