In 5th Grade, we made a blood model, in order to see the different components of blood:
We used some candy for:
- RED BLOOD CELLS, which carry the oxygen and the carbon dioxide thorough the body. They make 40% of the blood, so we made sure we added plenty of them.
- WHITE BLOOD CELLS, which protect our bodies from bacteria and microbes. There are fewer that the previous ones, so we used only a little of them.
- PLATELETS: which stop the bleeding in a wound.
- PLASMA: we used water but, in fact, we might have used another liquid because plasma is yellow.
It was easy and very visual. Are you going to do it at home using other ingredients???
