Science - Heart VR with stethoscopes
Students will learn why the heart makes the “lub dub” sound. Students will be able to demonstrate how blood flows through the heart.
|Name of Project: Heart VR with stethoscopes|
|Name of Project||Heart VR with stethoscopes|
|Driving Question / Problem / Activator||Can you explain why the heart makes a “lub dub” sound?Can you explain how problems with the heart may cause health concerns?|
|Project Summary||Students will learn why the heart makes the “lub dub” sound. Students will be able to demonstrate how blood flows through the heart.|
|Estimated Time||2 hours|
|Materials / Resources/Lesson Plans (including link to slideshow if available)|
|Tags||Heart, virtual reality, blood flow|
|Ask||What sounds does your heart make? What if your heart is not working correctly?|
|Plan||On the heart diagram, draw out the flow of blood through the heart and label the structures.|
|Create||Students 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.|
|Improve||Once 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 Reflections||Ticket 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 / Extensions||Blood Flow AnimationHeart Attack Animation Modifications:|

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.
