Logger Pro Project

  1. Throughout the length of this short project, I learned several things. That a team is only functional as long as every member contributes, how to use my mathematical skill and concepts in real life problems and situations, it taught me the different ways I might use my concept in real life, and about the trajectory and velocity of a ball depending on the speed it left my hand and the angle I threw it at. This directly relates to our quadratic units as all natural ball throws are parabolic with small anomalies due to resistance.
  2. Our group worked together very well, we were able to easily split up our work and help each other while at the same time getting the job done. With this method, we executed the instructions efficiently and successfully.
  3. Some of the challenges our grouped faced were technological errors and others were accidental miscommunication. While working, one of our computers ran out of battery and we had redo one of the videos, some of our saved documents got lost on the second day, and we accidentally graphed the wrong thing due to miscommunication in the group.
  4. We could have split up the work more evenly, there were some people in the group who actually did a lot of work, and others did less work (But they were still giving verbal help).
  5. If we were to do it differently, I would’ve made the 3 ball throws more distinct from each other, because 2 of the throws were very similar and was not as interesting.

Polymer Prototype #6 was our most successful prototype. After the polymer was made, it was a firm, smooth, sticky to itself, and very moldable. It had all the traits we needed for a medical polymer, in case we needed to wrap it around a finger, mold it as a cast, or stick it over a bruise for protection. We ran several tests on this, one it had to be sterile. We didn’t want mold growing on it or anything coming out of it that could infect any cuts or injuries. This was our residue test, our goal was to make it so the polymer kept to itself and did not leave any residue like liquid, color marks, or parts of itself. Prototype 6 passed this test, it was very clean and simple, it would be perfectly safe and sterile for injuries. Next, we wanted to test the firmness, if it was able to protect an injury. We tested this with one of my less favorite tests. I would get punched in the shoulder, and then have the polymer stuck there and get punched in the same spot. The polymer successfully reduced the pain from the punch evidently concluding that it was shockproof to a certain extent. Our last test was how long it would stick around injuries, this test made sure that the polymer could be used for longer durations. The injury we focused this test around was the jammed finger, we wrapped our polymer around the finger and bonded 2 fingers together to keep the injured finger still. We waited to see if the polymer would loosen up or slip off. It successfully maintained its latch to my fingers and provided its process for an entire class. Lastly, we obviously ran tests that benefitted customer satisfaction. We played around with the polymer for a long time, and it was not at all a mess, like I said, it was a firm smooth polymer that loved to stick with itself, but was good with not getting messy and sticking to everything else it touches. We also tested its sustainability, we wanted to see how many times we could reuse it for. For 4 classes, we put it on as a cast for 15 minutes and sealed it away, each time, the polymer worked correctly with no gradual defects as it aged. The guar gum is a galactomannan polysaccharide extract that alters the polymer to thicken and stabilize its current properties. This helps the polymer because according to an area of science called material science. The polymer itself has a lot of elasticity and firmness, but according to the physics of the polymer, it has a balanced range of elastic deformation and plastic deformation. This means that with relative smaller forces applied to the polymer, the polymer will rearrange back into its former shape, but if a more powerful force is applied, then it passes the plastic deformation point and causes permanent change. So this is technically not a nonnewtonian fluid, but its physical properties certainly differ from other slimes. This allows the polymer to wrap around fingers and at the same time hold its current shape. So to sum up, prototype 6 was our best polymer due to its functional physical properties, reliability, and customer satisfaction traits.

 

Overall, I think my team’s product pitch to the dream on team was successful. We addressed all parts needed: Originality, sustainability, and quality. If I were to do something different, I would probably try to be more prepared. It was my fault that i was unaware that the product pitch was on Tuesday and it caused me to hurry and not present my best. The whole polymer was pretty good, we successfully created a polymer that matched all traits and properties that we wanted. Maybe if we spent more time altering the traits, we could produce more types of the polymer for different purposes outside of the medical use. Our soft polymer did not have the most sustainable ingredients, it included 100 mL of PVA glue and 15 mL of borax, which are both not sustainable ingredients. The other ingredients are cornstarch and guar gum. Even though its not made of the most sustainable ingredients, we tested several times that it could be easily reused over and over, as long as once you were finished, you put it into a sealed bag. This makes the polymer more sustainable so you dont need to use wasteful ingredients everytime you make a new one. Lastly, our hardshell polymer is made of recycled polymers which is really sustainable.

Summer Reading List 2019


Reading List by Daniel

My summer reading list consists of To Kill a Mockingbird by Harper Lee, The Old Man and the Sea by Ernest Hemingway, A Walk in the Woods by Bill Bryson, and How to Think like a Fish by Jeremy Wade. The reason I chose To Kill a Mockingbird, is because it is an American classic. I have been recommended to read this book several times so I am sure it must be good. Next, I chose to read The Old Man and the Sea because one of my favorite hobbies is fishing, and a great way to learn is by reading, so combining the two into a classic book must be promising. Another book I have chosen to read this summer is A Walk in the Woods, I have decided for this to be one of my reading books this year because since I was a kid, I loved the wilderness. As was intrigued in this book as soon as I read the summary that it is about hiking the Appalachian Trail. Lastly, I chose to read How to Think like a Fish, the author for this book is Jeremy Wade, he has been a hero to me since a kid from when I started watching his TV series River Monsters. He has been my idol for very long and that is the main reason I chose to read that book. My goal each night for the summer is to read at least 30 minutes. This way I have a steady and constant rate of how much I’m reading so I can continue to push myself to finish reading my book list.

Our Polymer by daniel

To further elaborate, the traits we want for our first polymers are dryness, ability to stick to itself, firm, and flexibility. These traits will allow our first polymer to be the nice comfortable inside of any cast or patch for injuries. The traits will make it so the polymer will not be stick to everything but have the perfect firmness and flexibility to wrap around any part of the body and provide it with protection. As of the second polymer, we will be making it used from recycled plastics. The traits we are trying to achieve for this polymer is that it is very hard and study, has a cylindrical shape and has a hallow tunnel through it. These traits will allow the first polymer and the finger to be secured by a hard shell on the outside. With it’s very strong and durable physical features, as well as the softer polymer inside too, combined, it will provide its maximum protection for different parts of the body.

Our plan to develop different these prototypes is by using a trial and error process. For example, our prototype one was very watery and not as stretchy as we would like, those were the cons of the polymer. With that information, we changed small sections of our procedure to make, and attempt to correct those problems. We will use this method, and plan each next prototype based on information of past prototypes, this means that even though many of these prototypes are complete failures, these failures provide us with the data and information we need to succeed.

We will test the polymers by recording and observing how well it does in real situations. Like how long it will last, how long it takes before it dries, how durable is it against force, etc… By testing the prototype with these questions, we see if the polymer is fit to be used in real life.
