We're having loads of fun learning about body systems in Science. We started by exploring what a system is (anything made of parts that work together to do a job). The kids studied the parts of a flashlight and the parts of a phone at school then went hunting at home for the systems they live with everyday. They came back with great ideas. Some I completely expected (X-Box, PSP, TV, Computer, etc.), but others, like a door (parts: handle, lock, hinge, wood panels job: keep my little brother out of my room) and a Lazy Boy chair (parts: handle, padding, fabric, headrest, footrest, etc. job: let you be lazy), were a big surprise. You've gotta love 3rd graders!
We then turned our attention to the systems in our body (nervous, skeletal, digestive, respiratory and circulatory). As we study these systems we are trying to answer three essential questions.
- What are some of the jobs of this system?
- How can I keep this system healthy?
- How does this system work with the other systems we are studying?
Today in class we turned a balloon, cooking oil, and a wad of bread into a model of our digestive system. Ask your student to tell you how this helped them to understand #3!
