Ass you can see there are two different kinds of cells. Animal cells are round, and plant cells are rectangle and have chloroplast.
A couple days after doing this the boys were being really crazy and wild. I asked them why they were acting like animals. I guess they really got what the lesson was about, here is our conversations....
Me: Boys.... why are you acting like animals??!!!
Tommy: But mom... we are animals!
James: Yeah, our cells are round
Tommy: And we don't have chloroplast like plants do.
What do you say to that??? Nothing really... so I gave them apples and sent my little animals outside to play.
