🎯 What You'll Learn

Learning Objectives

1

Identify and describe three types of simple machines

2

Design a device using multiple simple machines

3

Demonstrate problem-solving skills through creative engineering

📖 Scripture Connection

Proverbs 8:12

“I, wisdom, dwell with prudence, and find out knowledge of witty inventions.”

— Proverbs 8:12 (WEB)

Just as this verse celebrates creative problem-solving, today's lesson encourages children to think creatively about how simple machines work together

Lesson Plan

1Opening (3 min)

Review simple machines we've learned about this year: lever, wheel and axle, pulley, inclined plane, wedge, and screw

💭 Review Question: Can you name a simple machine you saw working today?
2Teaching (10 min)

Explain how simple machines make work easier by reducing the force needed to move objects

📌 Key Talking Points:
  • Simple machines help us do work with less effort
  • Machines can change the direction or amount of force
  • Engineers use simple machines to solve real-world problems
💬 Discussion Questions:
  • What simple machines do you see in our home?
  • How might a pulley help someone lift something heavy?
3Activity: BibleMouse Simple Machine Invention Challenge (12 min)
project

Design and build a device that moves a small object using at least two different simple machines

📝 Instructions:
  1. Draw a quick design on your BibleMouse worksheet
  2. Gather materials from your supply kit
  3. Build your simple machine device
  4. Test and adjust your invention
  5. Explain how your machine works
🔄 Variations:

Simpler: Use pre-cut materials and follow a basic template

Challenge: Create a device that completes a specific task with minimal human intervention

4Closing (3 min)

Share inventions and discuss how simple machines work together

📝 Review Questions:
  • What simple machines did you use in your invention?
  • How did your machine make work easier?
