We had our monthly science co-op meeting this past week. We were studying blood and the circulatory system. The kids made models of the heart using graham crackers, frosting, and marshmallows.
Each family made a stethoscope to share
And I think the big excitement of the day was getting to explore a real cow's heart that another mom was able to bring in!
We also did blood typing. Henry backed out at the last minute, and I am not sure how to read the results of the other two boys. All in all it was a very good science day.
