Online animation helps pupils to gain an understanding of animal support systems - e.g. endoskeleton, exoskelton, hydrostatic skeleton. *4*Science lesson also provides limited sample questions at the end of the topic.*4**4**1*ANIMAL SUPPORT SYSTEMS*2*Explains that all animals have a support system which gives their bodies shape and helps them to move.*4*Explains that all animals need some support system to give them shape. Without a frame, the body would be a blob of jelly with no shape.*4*Explains the skeleton that is found on the outside of the animal is called the exoskeleton.*4*Explains that an exoskeleton, made from chitin, covers the body and protects the soft inside parts of the body.*4*Explains that chitin does not allow the animal to grow, so it has to moult when it grows bigger.*4*Explains a hydrostatic skeleton is made of muscles that are held up by a fluid in the body cavity. The muscles push against this fluid to help it move.*4*Explains a skeleton found inside the body is called an endoskeleton.*4*Explains the muscles and organs are attached to the outside and allow the animal to grow and help it move around.*4**4**4*Useful for teachers of science/biology
