Silk is Adaptable?

When one thinks of silk you tend to think of the nice tie you buy your father for a special holiday. However, silk can be used for various purposes such as nails, bone healing, vaccine carriers and much more. Silk has been prodded and adapted to be used for so many daily purposes.When silk was first discovered, there was no measure on how much it could be used for. Silk was used simply for paintings, clothing such as shoes, but how did we jump from all of this to drug distribution in a wound? Through finding properties to change to make a stronger product for each individual purpose.  Much like silk has been adapted and formed, in ancient Japan the samurai sword was adapted and changed to perfection. Although they didn’t have the technology we have today, ancient samurais crafted this sword to perfection enough so it can potentially slice through human bone. They experimented with metals to tweak the sword until it had the perfect properties and shape. These two items share the same idea because both were crafted or are still being crafted to become much more than what was anticipated at the start. Experimentation caused both of these items to potentially happen or exist.

1.3a Mini-lab MANIA

When comparing baking soda, corn starch, and baking powder one generally can’t make a clear distinction with the naked eye. However how would a scientist, or anybody for that matter, go about identifying each substance if it were given unlabeled? Through chemical and physical reactions! In our mini-lab, we had 3 samples of each of the stated white powders. To those powders we planned on adding a few drops of iodine, vinegar, and water. First we added Iodine to the 3 powders. Surprisingly, the baking powder turned a dark black and began to fizz. Next, we added the iodine to the cornstarch. Again, it turned black, but there was no fizzing. Then we added the iodine drops to the baking soda. Alarmingly, the solution was that of a yellow-orange color (same as the iodine liquid). Next we were to add vinegar to all the powders. The baking powder fizzed when the vinegar was added yet it did not dissolve. The corn starch had no fizzing or chemical reaction, but the solution was a milky color and it did not mix well. On the contrary, the baking soda and the vinegar got very fizzy when mixed. In fact we added a few more drops to the baking soda just to see how much it would react and it fizzed, or bubbled over the top of the container. It also was a milky white but composed that distinct chemical change. Lastly we added water to all of the powders. The baking powder got fizzy but it did not dissolve well. It was a milk white color. the Corn Starch was cloudy and also milk like but it separated when set down. The baking soda did not fizz, turned into an almost clear solution and you could see the individual granules at the bottom of the container. If someone was given one of these powders one could identify them by using iodine, water and vinegar and observing the physical and chemical reactions. Physical changes that would be observed may be changes of state, shape and the appearance but not the composition. Some chemical changes may be that a gas may have produced of any production of a precipitate. So yes someone could identify these powders by mixing them with these three liquids and observing their reactions to them.ImageImageImage

 

Passion is defined as a strong and barely controllable emotion. When something you do puts yourself at risk, but you still enjoy it one can tell that they are passionate about that precise thing. I was a very sheltered child in the aspect that my mom did not let me interact with someone who may cause me danger. As I walked with my mom in town I could not thwart the ache I received in my stomach when I saw someone on the side of the road in need. From the time I was a child I knew that I wanted to help someone else. This passion helps me when I am distraught. I love helping others to the point where I end up putting myself at a risk. The feeling it brings me is a phenomenal, unimaginable warmth. The simple act of keeping granola bars in my car in case of the event of passing someone on a corner and giving it to them brings me joy. This Thanksgiving I baked cookies and handed them out by the soup kitchen to those in need. The smiles that were reciprocated from the gesture were enough to make me do the same thing on Christmas day. Also getting involved in communities like rotary, NHS, and school wide functions make me feel alive in the community. I cannot end the ache I receive, but instead fill it with the passion that helps people. After all “every person lives two lives; the second begins when you realize you only have one.”

1.2a Bouncy Balls

To make a bouncy ball you combine a sodium borax and water mixture with regular school glue. The proportion of these elements are crucial to how the bouncy ball you create will turn out. First, my group started with 14 grams of glue and added 4mL of the borax and water mixture (which contained 10 grams of borax and 75 mL of water).  This bouncy ball had nice form and did not flatten out when set down on the table. We then thought that the glue was the element to increase to get the highest bounce to our ball. We then added 15 grams of glue with 5mL of the borax mixture to try and make a close match to the first product we created. We decided the second ball bounced a little better so we decided to make the final balls with 16.4 grams of glue and 5 mL of the borax mixture to increase the glue slightly hoping that the elasticity would drive the ball higher when bounced.  Our method was to increase the glue as much as possible without the ball being sticky or losing form. What we did not think of was the mass of the bouncy ball. Our bouncy balls weighed in at around 16 grams each and if we would have decreased the mass, the result might have been achieving a higher height when bounced. Good properties of a bouncy ball may include a smooth texture which ours somewhat achieved. The texture of our bouncy ball was slightly wrinkly, however it did not lose its shape which is also a good quality to obtain. The best portion of ingredients was the high glue to borax mixture ratio, but a small mass. These portions matter because it affects the shape and form of the bouncy ball, meaning it kept its shape. If there was too much borax mixture the ball would most likely sag or flatten once set down. The ratio is also important because it determines how high it will bounce which was the initial goal set. Trial and error was key to this experiment. We made many prototype balls before we decided to go with a final. Trial and error is a good method to go with because when you only have a suggested group of proportions you are left with wiggle room to experiment which elements will help you achieve your goal with a better bouncy ball. When you are mixing the ingredients and making the balls you can identify which method is going to work and you can tweak it so that you create a new and improved bouncy ball that can bounce higher with the lesser mass. This is an important matter because you can innovate upon the previous prototypes that were weaker and did not suffice compared to the final bouncy ball.
