This is Davan's main project for the day. She told me when we were watching two interesting things.
1) "That part sort of looks like cells splitting, but I didn't mean it to."
2) "That looks like it's the heart - with the veins and arteries flowing into it."
Can you tell that she's been doing anatomy and physiology? See if you can see which parts she's talking about. For a hint, #2 actually happens chronologically before #1 in the video.
