Reflective Questions:
How do we show that our design ideas were not just guesses and that my/our ideas and each of the proposed design attributes really is based on sound logic and subject related knowledge?
We performed research on the details of the products we are putting together, along with information from innovative companies and people. By calculating the amount required and testing cost and usability, we were able to come up with our initial solution. By using input from previous research and other engineers in similar fields, we were able to come up with the overall design which would effectively repel squirrels.
Why does this proposed solution have merit to try?
Our product, given a proper build, theoretically effectively solves the given problem with squirrels gnawing on power lines. The final design is viable: it can be used similar to the previous application without any extra bulk or other drawbacks. The final design also accounts for cost effectiveness and longevity, making it a testable prototype.
The problem that you choose to solve will certainly require known math, science and/or engineering concepts. This can include formulas, laws, etc. Brainstorm a list of math, science and/or engineering concepts that you anticipate will be needed in order to solve your team’s problem. Consider applications of mathematics, chemistry, biology, physical science, nanotechnology, electrical engineering, mechanical engineering, civil engineering, etc. that may be incorporated into your solution. Input from experts may be helpful in the identification of the concepts needed. You will continue to update this section as you research these principles and complete calculations.
Include:
Identify and describe science and engineering concepts you need to investigate.
Consider design stage, testing stage and data gathering stage.
Explicitly list and describe each concept you might use – relate back to design specs where possible.
Describe who can help you validate your STEM work – what are training or credentials will you need your experts to have?
Some engineering principles to consider: project management (Gantt chart), documentation (engr. Notebook), stress, strain, material properties.
Any special computer programs, technology or equipment you might use?

Connection to the project problem: Ensuring our group buys the proper and necessary materials to begin constructing and testing our product--Including using capsaicin with enough heat levels (Measured in SHUs) to effectively repel squirrels. Our group designated an appropriate amount of time deciphering which materials to buy and which materials not to buy. Along with buying the proper materials, our group also determined material quantities. For instance, our group decided to buy a less saturated, yet optimal capsaicin mixture with two ounces instead of a higher saturated mixture with only half an ounce. Not only our group saved money, but also bought enough capsaicin for enough experiments to test our product.

Relation to design specifications: Any situation in which we end up buying materials that don't follow our design specifications, constraints--time, cost, and effectiveness--would drastically hurt the team.

STEM Principle 2: Dimensions / Measurements (S / M)
The connection to the project problem: Understanding the specifications and parts the cable is better integrated with the capsaicin component. Optimizing the effectiveness of such product on squirrels that decide to chew on cables. Since we are testing our product on a variety of wires (Ranging from 0.2-0.4 inches), our group needs enough mixture to properly cover the wire shield. Given these measurements, it's important to compensate for wires of all varieties during testing.

STEM Principle 3: Three dimensional software drawings (T)
The connection to the project problem: Our group created a three dimensional sketch of a standard power wire, along with the Cap-Cable layer. Not only this technical drawing creates an accurate visual that is relatively easy for audiences to understand, but also provides our group with a final design--A guideline that helps our group during the construction phase, especially when encountering design specifications.
