Materials and Safety/Ethical considerations:
List materials used in the dissection
Safety and hygiene equipment:
All benches were wiped
1. A rat and a cane toad were dissected to compare their similarities and differences in anatomy structure. 2. Newspaper was laid out under the dissecting trays.
3. The external features of each animal was investigated and notes were collected. 4. The internal features of each animal were investigated and notes were collected. 5. Dissecting materials were placed into a container of Dettol. 6. The rat and toad were wrapped up into the newspaper and discarded in the bin. 7. Tables and aprons were sprayed and wiped down.
