All last week I shared some heart themed science activities. In case you missed them, they were:
Beat Your Heart
Race Your Heart
And for today, I'll leave you with some printable heart diagrams. Happy Valentine's Day!
You can find a plethora of heart diagrams on the Internet. Here are several different ones - some with spots to label, some plain, and some in color. To get the full-size image, click on the word link.
