🎯 What You'll Learn

Learning Objectives

1

Calculate net force in simple scenarios

2

Design and test experiments demonstrating force interactions

3

Develop curiosity about God's design of physical laws

📖 Scripture Connection

Colossians 1:17

“He is before all things, and in him all things are held together.”

— Colossians 1:17 (WEB)

Demonstrates God's fundamental role in maintaining physical forces and interactions

📦 Materials Needed

  • Spring scales
  • Various objects (books, blocks, toy cars)
  • Science notebook
  • Pencil
  • Ruler
  • Smooth surface (table or floor)
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

Recap previous lessons on force diagrams and balanced/unbalanced forces

💭 Review Question: What happens when forces are equal in magnitude but opposite in direction?
2Teaching (12 min)

Introduce net force calculation and experimental design

📌 Key Talking Points:
  • Net force determines object's motion
  • Forces can add or cancel each other
  • Experimental design requires careful measurement
💬 Discussion Questions:
  • How might different forces interact?
  • What makes an experiment scientifically valid?
3Activity: Force Interaction Challenge (18 min)
project

Students design and conduct experiments testing force interactions

📝 Instructions:
  1. Choose two objects of different masses
  2. Use spring scales to measure push/pull forces
  3. Record force measurements in science notebook
  4. Calculate net force
  5. Predict and then observe object's motion
🔄 Variations:

Simpler: Use fewer objects, focus on basic measurements

Challenge: Calculate complex multi-directional force scenarios

4Closing (5 min)

Summarize discoveries about force interactions

📝 Review Questions:
  • What did you learn about forces today?
  • How do forces work together in God's creation?

Coming up: Tomorrow we'll explore gravity and how it holds our world together
