SCIENCE 6TH GRADE - The heart

When I was a child I used to love this series... Here are some links to nice videos about how the heart works. Enjoy them!

These are videos from Youtube. The owner of this serie is: http://www.procidis.com/

You can also look for other functions or systems on Youtube. Just look for "Once upon a time life" and then "digestion", "breath" or the topic your are interested on.
