To design our polymer, we had to go through a design cycle which was complicated. We first had to define our idea. We were told by the dream on team to make a polymer that is related to furniture, we thought that we would make something to protect people from sharp edges since its both very useful and simple. We chose qualities from different sample polymers for example boogers and super slime and made some prototypes. We had a few prototype that could be used but at the end we decided to use prototype 4 and 3 together. We learned a lot of new things by making the prototypes. First we had to learn which ingredients work well together. We also learned new lab skill. We learned a lot of lessons from the dream on team that was very helpful. For example, we should have kept a sample of our polymer so we could have showed other people.
This is a found poem I made from the book An Act of Love by Alan Gibbons. This book is about two childhood friends, Chris and Imran slowly getting separated by racism and terrorism. I wrote this found poem because it related to how time has affected these 2 boys and how their friendship changed during this time. “What makes you think he’s going to have any time for you now?” (Alan Gibbons, 9). I think that this found poem fits the story well because of the connection it has with time and how it can change a lot of things.
How can war and terrorism wreck a friendship that easily just by it self. “Just switch your phone off. Leave him in the past where he belongs” (9, Alan Gibbons). Why would you want to treat your once best friend like that? What happened that made them not trust each other? 12 years of separation has changed the blood brothers. Religious discrimination and racism has caused them to take separate paths in life constantly fighting against each other.
Chris and Imran, are both protagonists in the book “An Act of Love” by Alan Gibbons. Their lives were very different then each other. These two people grew up together and was best friends. But something happened that made these two sworn blood brothers slowly break apart. Everything started separating once Chris moved houses. “My new home was a three-bed detached property on a quiet close.” (103 Gibbons) Chris had moved housed and became a soldier and goes to Afghanistan while Imran is involved with the Jihads, a group of Muslim extremists.
The book first starts 12 years later when Chris is about to receive a medal, but what he doesn’t know is that the terrorist group Jihad has a bomb around the area. Imran kept on trying to tell Chris that there is a bomb but he is half suspicious after what happened to their relationship. “I hold up my phone and he reads the message. Blood drains from his face.” (10 Gibbons). This was Chris’s father’s reaction after he reads the message Imran sent about the bomb. After this the book jumped back to 2000 and showed how these to blood brother’s relationships slowly get torn apart as they moved away from each other while flashing back to show what happened. “There was only one thing I could do. I turned and gave Link a shove. “Get off him!” … Link burst out laughing. “Want to play the hero, do you?” He butted me in the face.”. This quote showed how much the blood brothers used to care about each other. Through the tone of this passage, we can see that Chris is very caring and can do everything for his best friend.
These inseparable childhood brothers have fell apart slowly because of racism and terrorism. It is hard to imagine 2 really close friends have to face off against each other and stand the test. Chris and Imran, although different in color and race, both want their childhood back and back to being friends. At the end, it was their determination that saved themselves from any harm.
This is a gif I made using Gickr that represents the conflicts in the book An Act of Love, by Alan Gibbons. The book An Act of Love is about two boys who were really good childhood friends slowly getting separated due to war and racism. The main conflict in this story is person vs person. The two main protagonists in the story, Chris and Imran were blood brothers at the age of 7, but as time went by, Chris moved houses and joined the army to go to Afghanistan and Imran became in contact with a Muslim extremist group. “If we move now we can get him into a good high school” (Alan Gibbons 79). “My fingers hover over the keypad. I think about calling Imran Back. Can there be any truth in the message?” (Alan Gibbons 9). After getting separated for a few years, Chris and Imran does not fully trust each other anymore and Chris is debating with himself whether or not to call Imran. At the end of the story though, Chris and Imran’s friendship came back together after years of separation.
After making 3 different polymer prototypes, all of them seemed unique and had their own uses. Prototype #1 was the least successful out of all the prototypes. We used 15 ml of starch solution, 2 drops of food coloring, and 1 cm of PVA glue measured in a plastic cup. This prototype turned out to be very wet and did not stick together well. The polymer also had a lot of liquid in it and therefor had different chunks floating in the liquid. After this prototype dried, it shrunk and became really hard. Our second prototype was made with 20ml of PVA Solution, 5ml of borax, and 10ml of colored laundry starch. This prototype was really wet at first, but as it was left on a plate for a bit, it became not as wet. This polymer was also not ideal because it was not really durable and it became pretty hard once it dried. Our third prototype was made from 15 ml of colored starch, 10 cm of PVA solution, and 1 cm of PVA glue measured from a plastic cup. At first this prototype was sticky, but after a while it became less sticky and it was really moldable. This was also the most durable out of the 3 prototypes and had a soft center when hardened. The forth prototype is made out of 20ml of PVA solution, 3ml of borax, and half a spoonful of guar gum. This prototype was the most ideal for our project goal because it had a lot of the things we wanted. Although prototype 4 was really durable, it was not sticky enough to stick onto the table, so we decided to put prototype 3 and 4 together. To use it, you would have to put prototype number 4 on a sharp edge and use prototype number 3 to secure it on the edge. Some observations that led us to change our designs was that in the first prototype, we put both the borax solution and the starch solution which was not a good idea because it did not stick. We learned from our mistakes and in the second prototype we did not add both of them.
After doing the slime test on many different polymer, we recorded the data. Boogers smells like glue and has a slime rating of 2 because it is not really that slimy but it is stretchy. When slow poking, your finger gets covered by slime. When poking it quickly, your finger does not go through. When slow stretching it, it is very stretchy, but when stretching it fast enough, it will snap in half. It took the polymer 13 seconds to touch the table when placed on a 30 cm tall ruler and it also bounces 6cm when dropped from 30 cm. This polymer is decent for our goal since our polymer can protect people from sharp edges by putting it over an edge. We will add things from other polymers to improve and add on to it to further achieve our goal. To do that, the polymer needs some special characteristics like it can reshape easily, it does not get affected by gravity, it is easy to take off, and it will absorb impact. Mixing things from boogers and super-slime will result in something like it. We need to easily reshape it so we would take parts out of boogers. We also need the polymer to be durable so it does not break. We will use parts of the super-slime to make our polymer durable. We will make the polymer sticky by adding either the PVA solution or PVA glue. We will make 1 sample with the PVA solution and the other one with PVA glue. We will test how each one works by testing the durability of it, how does it get affected by gravity, and can it be reshaped easily and choose the one that fits the best.
Our goal for our polymer is to protect people from sharp edges on furniture. Sometimes people can run into a table that has sharp edges and get injured. with this polymer, you can put it over the edges of the table and it would absorb the impact every time someone bumps into it. Needs that will be met by creating this polymer would be safety. This polymer will significantly reduce the amount of injuries that will happen because someone accidentally ran into a furniture with sharp edges. Our target audience for this polymer are mainly old people and children because they are most likely to get injured. Some old people can’t walk properly, it would be very dangerous if they accidentally got hit on the edge. Children on the other hand, are still learning how to walk and are not fully developed yet and if they walked into a sharp edge, it would hurt them more and can scare them. The characteristics we want this polymer to have is that it should be be easy to reshape, and it can stick on to things easily and not get effected by gravity. This polymer should also absorb impact so it would be safer. This polymer needs to be easy to reshape because it would come in a ball shape and you can change the shape depending on the shape and size of the edge. This polymer also can not be affected by gravity because it has to stay in shape until someone reforms it to fit another edge. If this polymer is affected by gravity, it can drop onto the floor and it won’t stick on properly
Have you ever thought that a simple motion like closing your laptop, is related to math? Well it actually is. I was able to track the lid of my computer closing using a program called Logger Pro and turned it into a quadratic graph. The graph has how high the computer lid was in centimeters with the Y-axis and how long the time is in seconds with the X-axis. The Y-intercept of the graph is 21.29 and the X-intercept of the graph in between 0.7 and 0.8. This is a restricted graph because it has a starting point and has an ending point.
There are a lot of other examples of restricted parabola in the real world. For example, kicking a soccer ball is a restricted parabola because it has to have a starting point being where the person kicked it and it has to hit the ground after a while because of gravity. Shooting an arrow is also a great example because there has to be a person shooting it and it also has to fall onto the floor. Lastly, a metronome is a good option because it can not go into the ground therefor restricting its height.
Math is everywhere around you. Next time you see something, look closely at it because it might just be another parabola.
