🎯 What You'll Learn

Learning Objectives

1

Understand combustion as a rapid chemical change

2

Identify the key components required for fire

3

Recognize God's design in chemical transformations

📖 Scripture Connection

Exodus 3:2

“The angel of Yahweh appeared to him in a flame of fire out of the midst of a bush. He looked, and behold, the bush burned with fire, and the bush was not consumed.”

— Exodus 3:2 (WEB)

Demonstrates God's miraculous power through fire and chemical transformation

📦 Materials Needed

  • Safety goggles
  • Matches (with adult supervision)
  • Candle
  • Science notebook
  • Pencil
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

BibleMouse Science Explorers, today we'll investigate the amazing world of combustion - a powerful chemical change that transforms substances!

💭 Review Question: What signs of chemical change did we learn about in our last lesson?
2Teaching (15 min)

Combustion is a rapid chemical reaction where fuel combines with oxygen, producing heat and light

📌 Key Talking Points:
  • Three things needed for fire: Fuel, Oxygen, Heat
  • Fire changes substances into new materials
  • Chemical changes are permanent transformations
💬 Discussion Questions:
  • What happens to wood when it burns?
  • Why can't fires burn without oxygen?
3Activity: Controlled Candle Observation (15 min)
demonstration

Safely observe and document chemical changes during controlled burning

📝 Instructions:
  1. Put on safety goggles
  2. Observe candle flame with parent supervision
  3. Record observations in science notebook
  4. Sketch flame and note color, movement, heat
🔄 Variations:

Simpler: Draw flame without detailed notes

Challenge: Research molecular changes during combustion

4Closing (5 min)

Review key concepts of chemical change and combustion

📝 Review Questions:
  • What three things does fire need?
  • How is burning a chemical change?

Coming up: Tomorrow we'll explore rust as a slow chemical change
