plan, choose equipment or resources and perform a first-hand investigation of a mammalian eye to gather first-hand data to relate structures to functions
- You are required to perform a dissection of a mammalian eye, from an animal such as a sheep or bullock. Various biology practical manuals describe how to perform this procedure, or you can access the web site Exploratorium
, Exploratorium, Museum of Science, Art and Human Perception, San Francisco, California, USA, for some directions. Use these to plan and predict possible issues that may arise during the course of the investigation and decide how you will best gather your first-hand data.
- Perform your first-hand investigation by carrying out the planned procedure so that you minimise hazards and dispose carefully and safely of any waste materials. Identify and use safe work practices during this investigation.
- Draw a diagram to show the various structures you observe.
- Prepare notes to explain how the structures of the eye suit their function.
- Prepare notes to explain how you minimised hazards, disposed safely of any waste materials and used safe work practices during this investigation.
