Skeleton bicycle

Skeleton Bicycle - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

Operating instructions: 1. Get on the bicycle; 2. Step on the pedal and observe the changes in bone movement. Function Overview: Exhibition items consist of two synchronously moving bicycles, a darkroom, and a set of human skeletal models. There is a bicycle inside the dark box, on which a set of human skeletal models sit. The posture of the skeletal models is like a person riding a bicycle on top of them. The bicycles inside the dark box and outside the dark box can move synchronously through mechanical transmission, and the dark box is separated from the outside by semi reflective and semi transparent glass. When the audience rides on the bicycle outside the dark box, the lights inside the dark box slowly light up, and participants will see a complete and faintly visible skeleton riding inside the dark box, as if they were seeing their own skeleton in motion from a mirror. Scientific principles; Skeletonization is the foundation of the complexity of biological structures, and the skeletal system is a limiting factor in the evolution of biological morphology. Bones are the hard organs that make up vertebrates, responsible for movement, support, and protection of the body; Manufacturing red blood cells and white blood cells; Store minerals. Bones are composed of various shapes with complex internal and external structures, allowing them to maintain hardness while reducing weight. One of the components of bones is mineralized bone tissue, which has a hard honeycomb like three-dimensional structure inside; Other tissues include bone marrow, periosteum, nerves, blood vessels, and cartilage. The bones of the human body play a role in supporting the body and are a part of the human movement system. Adults have 206 bones. Bones are generally connected by joints and ligaments. Except for 6 ossicles belonging to sensory organs, they can be divided into 23 skull bones, 51 trunk bones, and 126 limb bones according to their location.
