Model Building by Annaliese

Do you like building? In our sixth grade science class right now, we are creating models! Not the fashion models and the make-up models, an actual science model. We just recently learned about the body systems (circulatory, muscular, respiratory, nervous, digestive and skeletal). After we made a book about all the systems, we moved onto the big part of the project...the building. Me and my group are doing the muscular system. For our model, we have taken three pieces of wood and cut them to size (about the size of our arm) we then attached them by using hooks and zip-ties. We are attaching balloons and rubber bands to show the muscles. If we bend the pieces of wood, one of the balloons stays the same size and the other contracts. This shows how the muscles move bones.
