Intro:
In this project, “Building a Scale Model” I decided to re-create a watch that I just so happen to wear everyday. At first glance I expected it to be difficult but after going through my thought process I realized that it didn’t have to be and I took a simple approach to tackling this challenge. The biggest concern I had was probably choosing the materials to make the object but I had a dive right in kind of mindset so the materials were decided along the way. Throughout this project I learned the process to actually creating a scale model. I also can say I learned all the work that goes into it. Overall I enjoyed this project very much and hope to be faced with projects like this in the near future. Down below are my calculations to creating this watch.
Calculations
Watch
Original:
Height: 10 in
Length (Band 1): 4.75 in
Width (Band 1): .75 in
Length (Band 2): 3.75 in
Width (Band 2): .75 in
Circumference: 4.71 in
Diameter: 1.5 in
Calculation for circumference: (3.14)(1.5) = 4.71 in
Scale Factor : 2
(Original Measurement) x (Scale Factor) = (New Measurement)
10 in (Height) 2 20 in
Rectangular prism:
4.75 in (Length) 2 9.5 in
.75 in (Width) 2 1.5 in
Rectangular prism 2:
3.75 in (Length) 2 7.5 in
.75 in (Width) 2 1.5 in
.0625 (Height) 2 .125 in
Cylinder:
4.71 in (Circumference) 2 9.42 in
.75 in (Radius) 2 1.5 in
.25 in (Height of cylinder) 2 .5 in
Broken up shapes:
Cylinder - (Watch)
circumference: 9.42 in
radius: 1.5 in
height: 1 in
Rectangular Prism 1 - (Band 1)
length: 9.5 in
width: 1.5 in
height: .15 in
Rectangular Prism 2 - (Band 2)
length: 7.5 in
width: 1.5 in
height: .15 in
Surface Area
Cylinder :
Circles: (3.14) (1.5) 2 = 7.065 * 2 = 14.13
Rectangle: 9.42 * 1 = 9.42
14.13 + 9.42 = SA: 23.55 in
Rectangular Prism 1 :
Rectangle: 2(1.5 * 9.5 + .15 * 9.5 + .15 * 1.5) = SA: 31.8 in
Rectangular Prism 2:
Rectangle: 2(1.5 * 7.5 + .15 * 7.5 + .15 * 1.5) = SA: 25.2 in
Surface area of Composite Solid = 23.55 + 31.8 + 25.2 = SA: 80.55 IN
Volume
Cylinder : (3.14) (1.5) 2 = V: 7.06
Rectangular Prism 1 : 9.5 * 1.5 = 14.25 * .15 = V: 2.13
Rectangular Prism 2 : 7.5 * 1.5 = 11.25 * .15 = V: 1.68
Volume of Composite Solid : 7.06 + 2.13 + 1.68 = V: 10.87

What were the challenges of this project? What was the hardest part?
In my opinion the hardest part of this project was creating the actual enlarged and/or dilated object. My main concern with the building process was deciding the materials I was going to use, but after I overcame that obstacle figuring out how to put all the pieces together became the new challenge. It was actually like making our own puzzles; simple at first the complicated after.
What did you like most about this project?
My favorite Part of this project was probably being able to choose the object we wanted to re-create. Being able to see how similar the objects were was astonishing, and truly made me think how did I do this, but along with great success comes great failure. When creating my object there were a lot of instances where I was forced to start over, but this showed me that there is always room for improvement
Give a real life example of how you can apply the skills you just practiced.
When I look at at the skills we just practiced I see; Observing and analyzing, and Constructing and Problem Solving. We observed and analyzed our object and solved the problems that came along when constructing them. When I think of this project along with the skills it obtains I think of how architects make small scale models to view what the bigger project is going to look like.
Here is a picture of my final product compared to the original:
