The Blood System

Science is actually fun! The two subjects in school that I thought I didn't like, World History and Science have actually become my favorites! I believe that children actually are little scientists. They are always asking questions and if you leave them alone they find things to experiment on, lol! With my oldest daughter I placed a heavy emphasis on literature and reading books with extensive vocabulary exposure, and that was great. But I'm learning that reading is more than just about big words, but it's about big ideas too.

Science has become another important aspect of our exploration of ideas. The subject we are currently learning is the human body. I'm being nice right now because I really want to use exclamation points, lol! It all started with a reading book on germs. One of our field trips at the library led to my collection of a book on germs which then led to the topic of cells. When you realize that all human life starts off as a single cell the topic of nucleus and mitochondria just mean so much more! So here we are entering into the world of biology first through reading and then through hands on inquiry.

We played a circulation game that showed the kids how blood travels throughout the body and how our cells are fed. The competition got real! The boys interacted with red blood cells, oxygen, carbon dioxide, along with sugars and proteins. We followed up our game with cups of tea and envisioned the impact of our drink with the circulation system at work within us.
