Learning Objectives

1

Understand how heat causes solids to change into liquids

2

Observe and record temperature changes during melting

3

Develop curiosity about how matter transforms

Psalm 147:16-17

He gives snow like wool, and scatters the frost like ashes. He casts out his ice like crumbs. Who can stand before his cold?

Psalm 147:16-17 (WEB)

Demonstrates God's power over states of matter and temperature

📦 Materials Needed

  • Ice cubes
  • Thermometer
  • Clear glass or container
  • Hot plate or warm area
  • Science journal
  • Pencil

Lesson Plan

1Opening (5 min)

Welcome to today's BibleMouse science adventure! Last time we explored how water can exist in different forms. Today, we'll watch ice transform before our very eyes!

💭 Review Question: What three states of water did we learn about yesterday?
2Teaching (10 min)

When we add heat to a solid, something magical happens - it begins to change into a liquid! Just like God carefully designs how everything in creation works.

📌 Key Talking Points:
  • Solids have a fixed shape
  • Adding heat makes molecules move faster
  • When molecules move faster, the solid becomes a liquid
💬 Discussion Questions:
  • What happens to ice when it sits in a warm room?
  • Can you think of other solids that might melt?
3Activity: Ice Melting Investigation (15 min)
hands-on experiment

Students will observe and record how ice changes when heat is applied

📝 Instructions:
  1. Place ice cube in clear container
  2. Record starting temperature
  3. Observe and sketch ice every 2-3 minutes
  4. Record temperature changes
  5. Note when ice completely becomes water
🔄 Variations:

Simpler: Use fewer ice cubes, focus on basic observation

Challenge: Graph temperature changes, predict melting time

4Closing (5 min)

BibleMouse scientists, you've just witnessed an amazing transformation that shows God's incredible design in nature!

📝 Review Questions:
  • What causes ice to melt?
  • What did you observe during our experiment?

Coming up: Tomorrow we'll explore how liquids can become solids - freezing!

Teaching Notes

📚 Background:

Molecular movement is key to understanding state changes

💡 Teaching Tips:
  • Use gentle heat sources
  • Supervise all heating activities
  • Encourage careful observation
🤔 Common Struggles:

Children might get impatient waiting for ice to melt

👀 Signs of Understanding:

Careful recording, curiosity about process

Extension Activities

  • Experiment with different types of solids melting
  • Create a BibleMouse science poster about matter changes

Ready for Tomorrow?
