Test 1 data: Usability
This test was very simple to conduct. After printing our final prototype, Liam took it home to test the two functions that it needed to perform; it's functionality as a utensil, and that it could be assembled, disassembled, and reassembled without major deformation or pieces breaking. SporkChops was successfully assembled after printing, disassembled soon after, then reassembled. After looking over the entire body and each utensil, Liam had found no deformations, cracking, or broken pieces on SporkChops, and reached the conclusion that it had passed the first part of our usability test. Next, the functionality of each different utensil of SporkChops needed to be tested. In order to test these, Liam used an apple slice, which would test the knife's ability to cut through food and the fork's ability to stab/pick up food. He then used a bowl of water in order to test that the spoon could scoop ad hold liquids. All three utensils passed their respective tests without deformation or any parts breaking, although the knife cannot be used unless being braced by the cap, as the base of it is not totally secure to the body. To conclude, the SporkChops final prototype fully passed the usability test, as it showed no deformation or any parts breaking while testing assembly, disassembly, reassembly, and testing on food.
Test 2 data: Material Conservation
For the material conservation test, which is meant to determine how much less waste is created in a 365 day calendar year by SporkChops than plastic utensils in school cafeterias, which are normally in session for 180 days out of the 365 day calendar year. To start, we recorded the mass of a pack of plastic utensils taken form our own cafeteria, which at the time was only a fork, so that was multiplied by three to account for missing utensils. We also recorded the mass of our prototype. Once we had recorded those masses, we multiplied them by the average daily attendance to our school, and then multiplied that found value by the number of needed utensils or SporkChops in the calendar year. The found value of the plastic utensil waste was divided by the found value of the SporkChops waste. This end value represents the magnitude by which our SporkChops reduces plastic utensil waste. Since this value is >1, this does indicate a reduction, meaning that our SporkChops prototype does indeed pass a material conservation test.

Post Test Adjustments
Due to the prototype being created last minute there was no real time to make adjustments to our design after testing, however after completing our testing we did realize there was no need for a redesign or adjustments. The SporkChops utensil was able to successfully pass all of Liams testing without any issues, however if i were to make changes to the design it would include finding a way to make the individual utensils a bit bigger since in many future cases such small utensils wouldn't work on many foods.
Individual Summary
The testing of our design was very simple because of our solution not being too complex unlike some of our classmates. To test our design we began by placing it through similar strains utensils have such as cutting, stabbing and spooning certain food items. This testing was done the day before our final presentation due to the prototype taking forever to be printed, however once it was printed Liam took it home to test. The purpose of our testing was to determine how well our design compared to commercially sold utensils. Due to the prototype being completed last minute we were not able to meet with our mentor one last time to present our project however he was sent screenshots of our final design and was pleased and liked our final design.
