🎯 What You'll Learn

Learning Objectives

1

Understand that light travels in straight lines

2

Demonstrate how light creates shadows

3

Appreciate God's design in how light works

📖 Scripture Connection

2 Corinthians 4:6

“For God, who said, 'Let light shine out of darkness,' has shone in our hearts to give the light of the knowledge of God's glory in the face of Jesus Christ.”

— 2 Corinthians 4:6 (WEB)

Just as light travels in a predictable way, God's truth shines clearly and directly into our understanding

📦 Materials Needed

  • Flashlight
  • White paper
  • Several small objects (blocks, toys)
  • Dark room or space
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

In today's BibleMouse science adventure, we'll explore how light travels! Remember yesterday's lesson about light sources? Today we'll see how light moves.

💭 Review Question: What are some light sources we learned about yesterday?
2Teaching (10 min)

Light always travels in straight lines - it doesn't bend or curve unless something stops or reflects it. This is how we see shadows!

📌 Key Talking Points:
  • Light moves in direct, straight paths
  • When something blocks light, a shadow forms
  • The closer an object is to the light source, the bigger its shadow
💬 Discussion Questions:
  • Why do you think shadows change size?
  • What happens when light hits different objects?
3Activity: Shadow Detective (15 min)
hands-on investigation

Create and investigate shadows using flashlights and objects

📝 Instructions:
  1. Dim the lights or go to a dark room
  2. Place a white paper on a flat surface
  3. Put a small object between the flashlight and paper
  4. Observe how the shadow forms
  5. Try moving the object closer and farther from the light source
🔄 Variations:

Simpler: Use larger objects for clearer shadows

Challenge: Create shadow puppet stories or measure shadow lengths

4Closing (5 min)

Review key concepts about light's straight-line travel

📝 Review Questions:
  • How does light move?
  • What creates a shadow?

Coming up: Tomorrow we'll explore how different materials interact with light - some let light through, some block it completely!
