Have paper, colored pencils, and children's basic anatomy books available at the center and have the following instructions posted:

1. Take a piece of paper and fold it in half from top to bottom.
2. On the top of one side draw a picture of a heart. On the bottom of that side, write information that you KNOW about the heart.
3. Using the books at the center, research the human heart.
4. Now, on the other side of the paper, draw a diagram of the human heart. Write some NEW things you learned about the heart below your drawing.

After all students have finished the center, have them reflect on the differences in what they thought the heart looked like and what it is anatomically. Help to clear up misconceptions.
