Grades 11-12 | Scalar vs. Vector Quantities | 1-Day Lesson

What it is
This 1-day lesson is designed for Grades 11–12 and focuses on scalar and vector quantities in physics. Students learn how to distinguish between these two types of quantities and apply vector addition in one- and two-dimensional motion.

Why it matters
Understanding scalars and vectors is essential for analyzing motion and solving physics problems. This lesson helps students move beyond definitions to apply vector concepts using both graphical methods and mathematical reasoning.

📄 What’s Included
This resource includes:

• Printable student handouts for guided learning
• PowerPoint presentation for direct instruction
• Interactive workbook activities, including:
  • Think–Pair–Share exercises
  • Making inferences tasks
  • PEEL short-answer responses
  • Vocabulary choice boards
• Materials suitable for both print and digital classroom use
• Answer key not included

👩‍🏫 How to Use
This resource works well for:

• 1–2 day lessons or motion units
• Whole-class instruction with guided examples
• Graphical and mathematical vector practice
