JSSS Student Understanding the function of joints through model making Investigation1 You have been given a template of a human ‘arm’ and some materials. Using these materials, try to construct a moving arm that most resembles reality. 1. Plan how you will construct your model _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ 2.

Draw a labelled diagram of your model 5. Could you improve on this model? _____________________________________________________________________________ 6. If so, explain your ideas using words or a labelled diagram _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ What information would a student need to find out before planning to build a model? _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ -2- JSSS Student -3- JSSS Student Investigation 2 You have been given a box of materials including wood, balloons, elastic, thread, scissors and sticky tape, protractor Use these to build a model of the hinge joint in you elbow. The model is to represent the movement of your elbow. The model must have the following features: Two bones below the joint - radius and ulna One bone above the joint – humerus Hinge joint moves almost 180° in one plane, like the hinge on a door Muscle and ligament are elastic; bone and tendon are non-elastic Bone is rigid; muscle, ligament and tendon are flexible Bones are joined to each other by ligaments Muscles are joined to bones by tendons The muscle contracting above the elbow pulls the lower arm bones upwards Muscle works as antagonistic pairs – when one contacts, its opposite relaxes What material would you choose to represent each of the following? Give one reason for your decision to choose this material. Component of arm Material chosen Reason Bone Muscle Ligament Tendon Describe your plan _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ Describe the method _____________________________________________________________________________ _____________________________________________________________________________ -4- JSSS Student _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ Describe the result _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ Draw a labelled diagram of your model Is there any other material you could have used that would have improved the model? ________ If so, name it and explain how it would have helped ___________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ _____________________________________________________________________________ -5-
