Project Outline 

AskWhat sounds does your heart make? What if your heart is not working correctly?
Imagine
  • VR Google Expedition “The Heart”.
  • Before going to slide four, listen to your table partner’s heart. Then  brainstorm what makes the “lub dub” sound.
PlanOn the heart diagram, draw out the flow of blood through the heart and label the structures.
CreateStudents working in pairs will create a Google Slides presentation using images found online. The slides should only contain pictures and a title. Once the slides are complete, students will use Screencastify to narrate the blood flow through the heart using the slides.
ImproveOnce the video is created, they will be able to view and edit the video as needed. The video will be their final product to be turned in.
Closure / Student ReflectionsTicket out the door or closing discussion: Now that you know how blood flows through the heart, how would blood flow be disrupted during heart disease?
Possible Modifications / ExtensionsBlood Flow AnimationHeart Attack Animation Modifications:
  • Create their own drawings (digital or by hand) instead of using found images
  • Use a resource such as padlet or flipgrid for students to view their classmates videos and provide feedback.

Additional Resources / Help for teaching this lesson

VR Google Expedition

  • Slide One
  • Explain common misconception: In the image it shows that veins are blue and arteries are red. Due to illustrations showing veins in blue, many people believe the unoxygenated blood in their body is blue. This is not true because it is the iron in blood that makes it red not the amount of oxygen.  
  • Ask: Why is the left side of the heart bigger than the right?
  • Slide Two
  • Ask what is the difference between a bicuspid and a tricuspid valve. Have them think of items that start with bi and tri to help them.
  • Slide Three
  • Direct to the Chordae Tendinae. Ask students what they think these “strings” do.
  • Before going to slide four, students will listen to each others/their own heart. They will work with a partner to brainstorm what makes the “lub dub” sound.
  • Slide Four
  • Direct to Sinoatrial Node - read the explanation of the nerve signals
  • Direct to Atrioventircular Node - explain when the “lub” of the heart is due to the two atria squeezing shut so the ventricles fill up.
  • Direct to Purkinje Fibers - explain this makes the “dub” sound as the blood gets pushed out of the ventricles into the arteries.
