Experimental Skills Cheatsheet

Cheat Codes & Shortcuts

  • Scientific Method: Observe, hypothesize, experiment, analyze, conclude.
  • Hypothesis: A testable prediction, often in "if-then" format.
  • Control Group: Baseline group with no variable changes.
  • Independent Variable: The variable you manipulate.
  • Dependent Variable: The variable you measure.
  • Precision vs Accuracy: Precision is consistency; accuracy is closeness to true value.
  • Error Analysis: Use \( \Delta x = \sqrt{(\Delta x_1)^2 + (\Delta x_2)^2} \) for combined errors.
  • Significant Figures: Report results based on measurement precision.
  • Data Visualization: Use graphs (e.g., scatter, line) for trends.
  • Lab Safety: Always follow protocols (PPE, chemical handling).

Quick Reference Table

Type Concept Key Point
Scientific Method Steps Observe, question, hypothesize, test, analyze, conclude
Variables Independent vs Dependent Manipulate independent; measure dependent
Error Analysis Uncertainty Combine errors: \( \Delta z = \sqrt{(\Delta x)^2 + (\Delta y)^2} \)
Precision Measurement Consistency in repeated measurements
Accuracy Measurement Closeness to true value
Safety Lab Protocols Wear PPE, handle chemicals safely

Advice

Plan Ahead: Design experiments with clear objectives and variables.

Record Everything: Keep detailed lab notes for reproducibility.

Check Equipment: Calibrate instruments before use.

Analyze Errors: Quantify uncertainties to validate results.

Stay Safe: Prioritize safety protocols to prevent accidents.

Experimental Skills Quick Tips

  • Hypothesis Testing: Formulate a clear, testable hypothesis.
  • Control Variables: Isolate the independent variable to ensure valid results.
  • Data Collection: Use consistent methods to reduce errors.
  • Graphing: Plot data to visualize trends; label axes clearly.
  • Error Propagation: Calculate combined uncertainty for derived quantities.
