Saint Inspired Science~ Circulatory System
This month we finally got to having our monthly science day with friends! Between bad weather and sickness, it was a little hard! Our saint this month was, quite obviously, St. Valentine! My friend found a great story book all about him to read. Saint Valentine was a doctor living in Rome in the early days of Christianity when people were being martyred for their faith. He worked very hard for people and, legend has it, he sent a note to one of his young patient after he was arrested and signed it “your Valentine”. Which is where we get valentines from! Now, since Valentine was a doctor and since hearts are a huge part of the holiday fun, we thought it would be fun to study the heart! We talked about how the heart works with its pumps and valves, how the heart rate goes up and down to pump more blood when you are working harder, and we even listened to how our heart sounds! We had an amazing experiment where we made a pump systems that worked like the heart using straws, balloons, and pint jars! We cut the bottom off a balloon, and stuck the end into a straw and taped it. Then we wrapped the large part of the balloon around a jar half full of water. Then, very carefully, we stretched a balloon over it and poked two holes in the told to put the straws in. For lunch I made heart shaped pizza pockets, heart shaped carrots, strawberries, pink juice, with ice cream sundaes for dessert!
