Core Idea

To establish the fundamental principles of scientific measurement, including the importance of standard units and an honest accounting for uncertainty.

Key Concepts

• SI Units (Système International)
• Uncertainty in Measurement
• Accuracy vs. Precision
• Significant Figures
• Dimensional Analysis

Essential Questions

• Why is it critical for scientists to have a shared system of units?
• What is the difference between accuracy and precision?
• How do significant figures help a scientist be "honest" about their measurements?
• What are the rules for using significant figures in calculations?
