Science class was all about the heart and lungs this week.
We made a stethoscope out of a cardboard tube and a balloon and listened to daddy's heart.
Then we made some lungs from paper straws and paper bags, when you blow in the straw the lungs fill up with air!!
We had a go at pumping a heart and saw how the blood moves around our body, and finally, we learned about the red and white blood cells and the platelets in our blood and did a separating exercise.
