Grasshopper Dissection Mitchell T. Heaton Objective: The purpose of this dissection is to familiarize myself with the internal workings of a grasshopper. Hypothesis: The internal and external features of this grasshopper will follow the aspects of a normal grasshopper. Materials: 1 Grasshopper 1 Scalpel 1 Dissection tray 10 Pins 1 Magnifying glass 1 Pair of scissors Methods: 1. Retrieve a grasshopper and lay it on the dissection tray. Examine it and compare its external features with the provided features of a grasshopper. 2. Make an incision from the anus to the back of the head. Use the pins to hold back the outer layer of skin. Make an incision just behind the antennas vertically across the front of the head. Observe the contents of the head, especially the brain.

Results: The internal and external structure of the grasshopper corresponded to previous documentation of grasshoppers and their body parts. Conclusion: The grasshopper I dissected is an insect with a complex system of organs and internal workings, not to mention its external complexity. The incision was initially difficult to make due to the chitin and the labeling of the internal workings was difficult as well. The overall complexity of the grasshopper is amazing and is a perfect example of the complexity of the workings of life....
