Part one: Blood
This morning we looked at the Circulatory system.
We read from Panoramas Human Body by Nicolas Harris. It has a great picture showing magnified blood. To learn more we made a model of the blood using water, cherrios, marshmallows and a pom pom (as you do). Water represented the plasma, the marshmallows were the white blood cells and the cherrios were the red blood cells. To show how the red blood cells were the 'red part' of the blood, we pretended they were getting oxygen from the lungs by coating them with red paint and then added them to the water/plasma.
This was the result....a somewhat gross looking jar of 'blood'. Miss K thought it was cool and disgusting at the same time.
