Challenges and Successes:
One of our biggest challenges while building the our kidney model was making it waterproof. We were constantly struggling to keep water from exiting our project, as there were many places for water to come out. Another challenge of ours was finding the right material to represent our waste in the project. We eventually settled on using sand. One of our successes was being able to not have to change very much of our model. We got it right the first time so we didn't have to use time to fix large problems. There were some small things that we had to do such as patching up leaks, but overall it went very smooth.
Final Model:
Our final model did its task as we wanted it to. It was able to remove waste from the bloodstream and send cleaned water or blood back into the body. Again even after we had worked to keep any water from leaking we still had minor leaks. These leaks did not effect the performance oh our model though and everything still worked as we wanted it to.
Presentation Night:
During the presentation night we got some good feedback on our model. One of the things that the judges brought up is that our model did not accurately depict kidney failure. Other than that though we got all positive feedback, the judges liked how simple yet effective our model was. How it showed the functions of the excretory system in a simple and easy to understand way. They also thought that our presentation was clear and to the point.
