# Plotting a New Point in My Learning Curve: Parabolas

The project we have been working on for the past few weeks has been on quadratics and parabolas. In this project, we built our own catapults and launched ping pong balls from them. We used Logger Pro to analyze the video of our catapult and wrote our Height vs. Time equation from it. Using that equation, we then proceeded to convert it into a Height vs. Distance function.

The most challenging part of the project was probably converting the equations. Most of our numbers were not whole numbers and were long decimals such as 0.1002. But I think that this step in the project was extremely pivotal because we were finally able to apply our learning to a real-world situation with random numbers. I think one of the most important learnings from this project was not only how to solve quadratics and draw parabolas, but also to understand that parabolas are used almost every day. This project helped my understanding of quadratics by putting me in a situation where the numbers are not already set. In this situation, I had to find the numbers myself and crunch them. I think next time I would try to do the equations more solidly and focus more on them. The equations are really one of the most important parts of the project and I think I overlooked it.

Prototype Claim

Use evidence from above observations to complete.

Prototype # 4, called MA-A4, was most effective for meeting our goal because: it had the best qualities and was well rounded. The qualities of the polymer suited our needs for product. Its Gloop like qualities allowed it to be stuck on to a pliable surface. It was stickier than Mark II and Mark III but more elastic and squishier than Mark V.

Method of Final Design

Make sure you list the steps and amounts used.

1. Add 73.9 grams of glue into a cup
2. Measure 40 ml of PVA solution and add to the same cup
3. Measure 20 ml of borax and add to the cup
4. Stir with spoon to combine
5. Next combine 1.2 grams of guar gum to the mixture
6. Mix the slime until too thick to mix
7. Add 10 ml of Liquid Starch to the mix and stir well
8. Lay the slime onto a clean flat surface and continue to knead until not slippery or too sticky
9. If needed put the slime under tap water for a couple seconds and pat dry with a towel.
10. Apply onto any object and make sure it sticks well before using.

Reflection

What was the process like?  What was challenging?  What was interesting?  What did I learn?

The design process for this project was the most challenging part of the project for me. For my group, the slime took lots of time to make and any change in quantities could modify the result of the slime. I think what was most interesting was how we could apply this knowledge from the slimes to learn more about chemistry and how polymers work.

# “AIR” + “ENERGY”+ “RENEWABLE” —–> “SAVE THE WORLD”

The issue I would like to focus on is the issue of renewable energy and how CO2 emissions affect our air quality. I currently believe that China’s primary source of energy comes from burning coal. However, the burning of coal creates pollution. I also think that Germany is doing a great job currently in using renewable sources and we should model what they are doing. Germany is already dubbed as the “the world’s first major renewable energy economy.” Renewable energy is affordable, cleaner, and is going to be better for the environment.

How will the reduction of Co2 emissions (switching to renewable energy) affect the economy of China? Will the pros of the switch outweigh the cons? What measures will the government take?

I fear that I may not have the correct information or solutions. I also worry that I may be too naive and that I don’t understand the significant impacts of suddenly switching to a new source of energy.

I hope to gain an outlook on how some small changes can really affect a big country. I also want to learn more about renewable energy sources.

I hope to spread awareness that pollution really affects our lives. That some toxins in the air are already 20 times the limit. That our actions can save us and our future.

I would appreciate your feedback to know if my question is too broad or if there are any ideas I am not covering.

# “Life, Liberty, and the Pursuit of Happiness”

He was a man in his early forties, specks of grey hairs sprouting out of the sides of his head. He sat alone at his desk by candlelight, as he pulled out an old worn out a journal with the name, “GEORGE H. JACKSON” engraved on it. Slowly, with his wrinkled hands, he shakily grabs the book and guides it to the light. But then he retracts from the candle and lays the book on his desktop. He opens the journal dives back into his youth.

The question behind every revolution is what changed and stayed the same. Quite honestly, pretty much everything remained the same after the American revolution. We went from rich white guys running the show all the way to rich white guys running the show. Slavery was still in place, and it became even more significant in the Southern states. Treatment of Native Americans mostly remained the same. They were often prosecuted, and those who sided with the British had their villages burnt. Wealthy landowners and merchants still dominated society and politics. Even though women helped a lot to win the Revolution, the war never really changed the roles of women. They were always considered wards of their husbands or saleable assets of their fathers, and they didn’t gain personal rights.

What was revolutionary were the ideas. These ideas can be summed up in one of the sentences of the Declaration of Independence: “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their creator with certain inalienable rights and that among these are life, liberty, and the pursuit of happiness.” The ideology of “all men are equal” was not initially shown as there were still slaves in use, it, later on, it presented itself in our American culture. The revolution also profoundly changed the economy. We also began to see the notion that all Americans where equal, that birth didn’t decide what job you got or your status in society. Now, you had the chance to work your way up and become wealthy. There was no significant social or financial gap in society.  With this new country, all men and women worked their fair share and earned their keep. With this idea, it not only profoundly shaped America but also began to mold revolutions and ideas for the rest of the world we know today.

# The American Revolution In Plain English

This video explains key events of the American Revolution. The revolution was slight 360-degree turn from what America was before. The revolution could be summed up with “history is written by the victors.” Although the ideas of the Declaration of Independence not shown at first, the victory of the Colonists and their ideas helped shape America and revolutions to come.

# Bittersweet: The Global Impact of Sugar

A chef mixes sugar and cinnamon to make a dip for freshly made churros. In another restaurant, a woman mixes in “white gold” to egg whites to make a base for a soufflé. Contrast to popular belief, sugar is not a fattening or sweet material, but the catalyst for change in many ways. Sugar Changed the World allows for readers to broaden their views on sugar. It is clear that the central idea that the authors were gunning for was how sugar truly impacted the world. We can see from revolutions to the birth of different cultures, sugar changed the world.

Sugar is just not only part of a recipe or common ingredient, it could be kindling for revolutions and wars. It all started on the “sugar islands.” Conditions at slave islands were torturous. An “overseer” of slaves once “gagged [a slave]; locked his hands together; rubbed him with molasses and exposed him naked to the flies all day, and to the mosquitos all night” (Aronson 59). Soon, slaves on sugar islands began to revolt due to the brutal treatment. In the fall of 1791, King Louis XVI declared that slaves were legally equal to average Frenchmen. In 1799 Napoleon Bonaparte put an end to the French Revolution. Bonaparte, realizing how important sugar was to France, reinstalled rules that originally freed French slaves. Bonaparte also went to war with the rebellious slaves on Haiti, which lost him the lives of 50,000 men. France pulled out of the island, and in 1804, the Republic of Haiti was born.  With that, Bonaparte lost one of his most productive and most efficient sugar producing island. As a result, he sold Louisiana to North America to pay the war debt. Thus causing it to become a state. From the wars waged and revolutions fought, sugar caused lives to be lost, and debt to be paid. This is just one reason how sugar changed the world.

The life of a slave gave birth to new music and culture. Sugar slaves were meant to work and die. No interview of an African slave has been documented. We may never have been able to hear their stories first hand, but the beat of their lives still echoes with the music they created. In Puerto Rico, Bomba is a form of music and dance sugar workers invented. In Cuba, sugar workers told stories through the Rumba, another type of dance that carried on the pulse and stories of their lives. One song even said, “The boss does not want me to play the drum” (Aronson 54). Back then, slave “Overseers” feared that the music would spread revolutionary thoughts and ideas. These songs and different musical cultures are the remnants of the sugar trade and slavery that went down from the early 1700s to the mid-1800s. Sugar trade helped shaped these cultures and inform future generations on the historical relationship between slavery and sugar. Once again, sugar can be linked to the creation of many things.

From happiness, flavor, and culture, to war and revolution, we can see that sugar not only satisfies our taste buds but also impacts the lives and cultures of many people. We keep a record of the past to make sure that events are not repeated. The slaves that worked relentlessly for nothing unfortunately died, but not in vain. They will be remembered. Their deaths and scars will be a mark in history. The slave trade of the early 1700s to the mid-1800s will be remembered as signs of when humanity turns to greed, not compassion. Ironically, the sweetness of sugar brought pain and sorrow to many. These marks in history prove how sugar profoundly changed the world.

# The Misadventures of Tom Sawyer

For this multimedia post, I chose to use the app Thinglink. The app allows the user to apply annotations to a picture and tag different details. Mark Twain is arguably one of the most descriptive writers in history. Using Thinglink and the aforementioned details to my advantage, I was able to tag out different details from the book that help convey the mood. The scenes depicted were the graveyard scene and the famous whitewashing scene. The book I read was Tom Sawyer.

# Substance abuse, Body Image and Healthy Choices

What are the dangers of using substances to alter body shape?

Many of the dangers of using these types of drugs include heart problems or heart problems. Most dangerously, these drugs can harbor side effects that can be mental issues. These drugs are meant for weight loss but drugs like Meridia can cause suicidal thoughts, depression and even sudden death.

What is a healthier option?

DON’T CUT CORNERS. NO PAIN NO GAIN. Getting stronger, faster, and better always requires the breaking down and building yourself back up. Its always gonna hurt and there’s no way you can escape that.
