🎯 What You'll Learn

Learning Objectives

1

Understand how weight impacts friction force

2

Design and conduct a scientific experiment controlling variables

3

Develop curiosity about how God's physical laws work in creation

📖 Scripture Connection

Proverbs 3:19

“Yahweh by wisdom founded the earth. By understanding, he established the heavens.”

— Proverbs 3:19 (WEB)

Just as God designed precise physical laws governing friction, He created scientific principles that reveal His intelligent design

📦 Materials Needed

  • Wooden board
  • Spring scale
  • Different weights (books, rocks)
  • Sandpaper
  • Smooth surface
  • Science notebook
  • Pencil
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

Review previous friction experiments and introduce today's investigation of weight's impact on friction

💭 Review Question: What did we learn about different surfaces and friction yesterday?
2Teaching (12 min)

Explain variables in friction experiments, focusing on weight and surface interaction

📌 Key Talking Points:
  • What is a variable?
  • How does weight change friction?
  • Scientific method steps
💬 Discussion Questions:
  • What do you predict will happen when we add more weight?
  • How might friction change on different surfaces?
3Activity: Friction Weight Experiment (18 min)
hands-on

Systematically test how weight affects friction using spring scale and different surfaces

📝 Instructions:
  1. Set up wooden board at slight angle
  2. Place object on board
  3. Measure force required to move object using spring scale
  4. Record results in science notebook
  5. Repeat with different weights
  6. Compare and graph results
🔄 Variations:

Simpler: Use fewer weight increments

Challenge: Calculate precise friction coefficients

4Closing (5 min)

Summarize experimental findings and scientific observations

📝 Review Questions:
  • What happened when we changed weight?
  • How does this experiment help us understand God's design?

Coming up: Tomorrow we'll explore ways to reduce friction in engineering
