Instructional Ideas

  • Use Virtual Heart as a visual aid when you are teaching about the heart
  • Class members can review structures of the heart with labels on, record each in science journals, and then research the role of each labeled feature
Classroom Considerations

Informative text only appears once, the first time you tap on any one of the scrollbar choices:

  • The heart is roughly in the center of the chest
  • Laughing increases blood flow
  • A bundle of special nerves acts as a pacemaker
  • Valves open and close two at a time and are what create heartbeats
  • It takes 20 seconds for blood to circulate throughout the entire body

Other than the above information, this app serves mainly as a labeled model.

Pros

  • Accurate representation of heart structure and function
  • Realistic imagery
  • Simple and easy to navigate
  • Can be used with Next Generation Science Standards HS-LS1-2
Cons

  • The only communicated information appears one time in print, only for a few seconds, and cannot be reviewed without exiting the app and starting over
  • Only viewable in portrait orientation
