Skeletal System
http://www.42explore.com/skeleton.htm Skeletal System A skeleton is an inner framework made of bone and cartilage. Bones are the hard material of a skeleton. The skeleton supports and/or protects the softer body parts of a fish, bird, or human. These animals are called vertebrates. They all have a backbone. A human skeleton generally forms about 206 separate bones out of cartilage as it develops to maturity. Bones are connected to adjacent bones by joints. Joints are either movable as in the arm and leg or immovable as in the skull. |

Movement
http://http://www.digitalbrain.com/digitalbrain/public/subjects/1.%20primary/ks2sci/su2/mod2/exercise3.db_psc We move by using a system of muscles and bones. Our skeleton supports, protects and allows us to move. Our muscles pull on our bones to move them. The skeleton is joined together by ligaments at joints. Muscles joined to the bones by tendons move the bones. Muscles can only pull, they cannot push, so, to move a joint in both direction two muscles are needed. Muscles usually work together in pairs. |

Moving & Growing - 4learning
http://www.channel4.com/science/index.html Some animals have a backbone. Some do not. Animals with backbones are called vertebrates - backboned animals. Backboned animals have a hard body frame inside them - their skeleton. Fish, amphibians, reptiles, birds and mammals have a skeleton. You are a mammal. You have a bony skeleton. Your skeleton grows with you Muscles are able to contract and relax. When they contract, they pull on your skeleton. You move. |

Moving and growing (4a)
http://www.standards.dfes.gov.uk/schemes2/science/sci4a/?view=get Through this unit children learn about how the skeleton is related to movement and support in humans and what happens to the skeleton and muscles as they move. They also compare human bones and skeletons with those of other animals. Experimental and investigative work focuses on: -turning questions into a form that can be investigated and collecting sufficient evidence -making observations, measurements and comparisons -interpreting evidence. Work in this unit also offers opportunities for children to relate understanding of science to personal health. This unit takes approximately 12 hours. |
