🎯 What You'll Learn

Learning Objectives

1

Understand how pulleys change the direction of force

2

Construct a simple pulley system

3

Recognize God's creative design in mechanical advantage

📖 Scripture Connection

Ecclesiastes 4:9

“Two are better than one, because they have a good reward for their labor.”

— Ecclesiastes 4:9 (WEB)

Just as pulleys work together to make lifting easier, people can work together to accomplish more

📦 Materials Needed

  • Rope or strong string
  • 2-3 small pulleys (or makeshift pulleys)
  • Small bucket or lightweight container
  • Small weights or rocks
  • Sturdy hook or clothesline

Lesson Plan

1Opening (3 min)

Recall our previous lessons about simple machines. Today, we'll explore how pulleys help us lift things more easily!

💭 Review Question: What did we learn about levers yesterday?
2Teaching (10 min)

Pulleys are amazing tools that change how we move things. They're like helpers that make lifting easier!

📌 Key Talking Points:
  • A pulley is a wheel with a groove where a rope can move
  • Pulleys can change the direction of force
  • More pulleys can make lifting even easier
💬 Discussion Questions:
  • Can you think of places where you've seen pulleys?
  • How might pulleys help people do hard work?
3Activity: BibleMouse Pulley Challenge (12 min)
project

Build a simple pulley system and test how it makes lifting easier

📝 Instructions:
  1. Attach a hook or use a clothesline
  2. Hang your first pulley
  3. Thread rope through the pulley
  4. Attach a small bucket or container
  5. Try lifting the weight with and without the pulley
🔄 Variations:

Simpler: Use just one pulley and help child observe the difference

Challenge: Create a multi-pulley system and calculate mechanical advantage

4Closing (3 min)

Record observations in your BibleMouse Science Journal

📝 Review Questions:
  • What did the pulley help us do?
  • How did the pulley make lifting easier?

Coming up: Tomorrow we'll go on a Simple Machine Hunt around our home!
