🎯 What You'll Learn

Learning Objectives

1

Understand how to measure and record pulse rates

2

Identify different pulse locations in the human body

3

Recognize how physical activity impacts heart rate

📖 Scripture Connection

Psalm 139:14

“I will give thanks to you, for I am fearfully and wonderfully made. Your works are wonderful. My soul knows that very well.”

— Psalm 139:14 (WEB)

Highlights the intricate design of the human body and its amazing circulatory system

📦 Materials Needed

  • Stethoscope (or optional DIY paper tube)
  • Stopwatch or timer
  • Science notebook
  • Pencil
  • BibleMouse Science Recording Sheet
📚 Step-by-Step

Lesson Plan

1Opening (5 min)

Begin by asking students to place their hand on their heart and feel its rhythm. Discuss how God designed our bodies with incredible complexity.

💭 Review Question: What did we learn about blood's journey through the body yesterday?
2Teaching (10 min)

Explain pulse measurement techniques and heart rate variations

📌 Key Talking Points:
  • Locate pulse points: wrist, neck, inside of elbow
  • Demonstrate proper pulse measurement technique
  • Discuss how heart rate changes with activity
💬 Discussion Questions:
  • Why do you think our heart rate changes?
  • How might exercise affect our heartbeat?
3Activity: Heartbeat Tracking Investigation (20 min)
hands-on

Students will measure and record pulse rates at rest, after walking, and after running in place

📝 Instructions:
  1. Measure resting pulse rate for 15 seconds and multiply by 4
  2. Walk in place for 1 minute
  3. Immediately measure and record pulse rate
  4. Run in place for 1 minute
  5. Immediately measure and record pulse rate
  6. Complete BibleMouse Science Recording Sheet
🔄 Variations:

Simpler: Use shorter activity durations

Challenge: Create a graph showing pulse rate changes

4Closing (5 min)

Discuss findings and marvel at God's design of the human body

📝 Review Questions:
  • What did you notice about your heart rate?
  • How does physical activity impact your pulse?

Coming up: Tomorrow we'll create a model of the circulatory system to visualize blood flow

👨‍👩‍👧 For Parents
