To what does your group contribute the success of the group?
Our group was successful because we worked together well as a team. As a team, we were able to trust each other to finish our classwork at home allowing us to stay up to date with current work and use our class time most efficiently. Because we were able to stay on schedule, the project was manageable and not overwhelming.

To what does your group contribute the failures of the group?
Although we met all of our success criteria, our bear could have come closer to the ground. If our bear had been within 0.25 meters, we would have scored more points. We believe our bear didn't come within this 0.25 meters because of sources of error resulting in the differences between our simulation results and our actual results. Our simulation predicted that our bear would fall within 0.25 meters. However, our actual elastics may have had a different spring constant than our simulation had calculated, resulting in the difference between where our bear actually fell and where we expected it to fall.
What did your group learn by doing this engineering design challenge?
During this engineering design challenge, our group learned a lot. We learned that it takes lots of preparation and design to create a functional prototype of a product. We also learned the relationship between elastics and springs. You can use the same methods to find the spring constant of the elastics. For instance, in parallel elastics and springs, K1+K2 can be used to find K parallel. As well as for series, the sum of the reciprocals of K can be used to find the reciprocal of the spring constant of the series. It was also interesting to see the real life application of the springs in action.
