Recycled heart: Everyone has that one friend out there... the one who eschews hearts and flowers and prefers a more visceral reality. If you need to give that person a valentine's gift, this reuse idea is for you.
I really like all of these ideas for learning about the heart because they can be used for many ages. Some of the younger children may find the model of the house representing the heart easier to understand and more relatable. School age children may find the actual heart and body activities as more of a challenge and enjoyable project. This can help children going through something cardiac related understand procedures or problems occurring.
