Materials or Fees
Question and Wonder:
- What is moving inside your body even when you are standing still?
- Are there things inside you that move all the time? What are they?
- How can you tell they are moving?
- Why are they moving? What are they doing?
- Is there any body part you can see that moves when you are still? What is it?
Imagine and Design:
- What are ways you can feel, hear, or see the things inside your body that move?
- What tools do doctors use to “see” those things?
- How can you track those movements?
- Could you make tools that do what a doctor’s tools do? How? What could you use?
Stand perfectly still in front of a mirror. What do you notice? Is anything moving? Lay down on the floor or your bed and put a book on your chest. Keeping your eyes on the book, lay still. What do you see?
Make a stethoscope: Put the small end of the funnel inside the tube and secure with the tape. Place the wide end of the funnel flat against a partner’s chest and put your ear against the other end.
Test and Discuss:
- What did you hear through your stethoscope?
- How does that tell you the heart is moving?
- How does the book on your chest show you the movement of your breathing?
- What other ways can you tell your heart is beating?
- Why is your heart beating? What is it doing?
- Does your heartbeat change when you move? How?
- What about your breath?
- When you looked in the mirror did you see anything moving?
- Are you aware of your heart beating? Eyes blinking? Lungs breathing? Why?
