Have your kids ever asked you why they need to breathe? Or why they get tired from running? Well, that’s the work of our lungs so that they can get oxygen to our body.
This paper bag lungs activity is fun and give kids a really great idea of how our respiratory system works. They are the perfect addition to a homeschool human body unit and I love that they are usable from preschool up to older children to demonstrate how our bodies work.
Simple hands on science ideas are often the best and most memorable science projects that you can do with your child. Including them on the project from start to finish helps it really sink in and stick the way a worksheet might not be able to.
