🎯 What You'll Learn

Learning Objectives

1

Identify and describe three different types of chemical reactions

2

Observe and record signs of chemical changes in experiments

3

Develop careful scientific observation skills as a way of honoring God's creation

📖 Scripture Connection

Colossians 1:17

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

— Colossians 1:17 (WEB)

Just as chemical reactions transform substances, God sustains and transforms all of creation through His power

📦 Materials Needed

  • baking soda
  • vinegar
  • steel wool
  • salt
  • safety goggles
  • science notebook
  • clear glass containers
  • plastic spoon
  • paper towels
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

Welcome to today's BibleMouse science adventure! Yesterday we learned about chemical changes, and today we'll explore how substances can transform in amazing ways.

💭 Review Question: Can you remember two signs that a chemical change has occurred?
2Teaching (10 min)

Today we'll conduct three safe chemical reactions to see how new substances form

📌 Key Talking Points:
  • Chemical reactions create entirely new substances
  • We can observe chemical changes through specific signs
  • God designed the amazing world of chemical interactions
💬 Discussion Questions:
  • What do you think might happen when we mix baking soda and vinegar?
  • How might chemical changes be important in everyday life?
3Activity: Three Chemical Reaction Experiments (20 min)
hands-on

Students will conduct three carefully supervised chemical reaction experiments

📝 Instructions:
  1. Put on safety goggles
  2. Experiment 1: Baking Soda and Vinegar Reaction
  3. Experiment 2: Steel Wool Oxidation
  4. Experiment 3: Salt Water Conductivity Test
  5. Record observations in science notebook
🔄 Variations:

Simpler: Perform fewer experiments with more guided observation

Challenge: Research additional chemical reaction types and hypothesize results

4Closing (5 min)

Review observations and discuss how chemical changes demonstrate God's intricate design

📝 Review Questions:
  • What new substances did we create today?
  • What signs of chemical change did you observe?

Coming up: Tomorrow we'll dive deeper into combustion as a special type of chemical change
