🎯 What You'll Learn

Learning Objectives

1

Understand that heat causes liquids to turn into gases through evaporation

2

Observe and record water disappearing from an open container

3

Develop curiosity about how God's creation changes and transforms

📖 Scripture Connection

Genesis 1:2

“The earth was formless and empty. Darkness was on the surface of the deep. God's Spirit was hovering over the surface of the waters.”

— Genesis 1:2 (WEB)

Just as God's Spirit moved over waters, water itself moves and changes, demonstrating the dynamic nature of God's creation

📦 Materials Needed

  • 3 clear glass containers
  • Water
  • Sunny windowsill or heat lamp
  • Measuring cup
  • Marker
  • Science journal
  • BibleMouse science recording sheet
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

In today's BibleMouse science adventure, we'll explore how water can disappear into thin air!

💭 Review Question: What did we learn yesterday about how liquids can become solids?
2Teaching (10 min)

Evaporation happens when liquid water turns into invisible water vapor due to heat

📌 Key Talking Points:
  • Heat makes water molecules move faster
  • When water gets hot enough, it turns into an invisible gas
  • This process is called evaporation
💬 Discussion Questions:
  • Where have you seen water disappear?
  • What makes water evaporate more quickly?
3Activity: Watching Water Vanish (15 min)
investigation

Students will track water evaporation in different conditions

📝 Instructions:
  1. Mark water level on 3 containers
  2. Place one in sunlight, one in shade, one near heat source
  3. Check and measure water loss every hour
  4. Record observations in science journal
🔄 Variations:

Simpler: Just observe one container

Challenge: Graph water loss and calculate evaporation rate

4Closing (5 min)

Review evaporation observations and discuss findings

📝 Review Questions:
  • Where did water disappear fastest?
  • What caused the water to evaporate?

Coming up: Tomorrow we'll learn about condensation - how gas becomes liquid again!
