This week we began our study of the circulatory system. The children learned how our heart pumps blood around our body, and carries oxygen to all different areas. We also discussed how blood gains oxygen from our lungs when we breath and becomes oxygenated blood. After this oxygenated blood travels throughout our body and all of the oxygen has been used, it is called deoxygenated. The children then created their own scientific model of the heart, with different colored yarn acting as the oxygenated and deoxygenated blood throughout our body.
After our discussion of the heart, we worked together to create our own “blood” in the sensory table. We discussed how blood is actually made up of many different parts, that each have a different role. The red blood cells carry the oxygen, and other parts of the blood play different roles in keeping our body healthy.
We look forward to sharing our understanding of the circulatory system with our biobuddies in few weeks!
