This is a DNA strand from a cell inside my cheek! Looks super weird, kinda like a spider-web almost, but it’s cool, right? Well, with the help of dish soap, salt water solution, and alcohol, I was able to isolate the DNA strand from inside the nucleus of the cells inside my cheek.
This lab was to find out which brand gum, between Hubba Bubba and Big League Chew, could produce the biggest bubbles and how the different products stretched. Both gums weighed 7.9 grams. Hubba Bubba was Gum A and Big League Chew was Gum B. Gum A was purple and had a thick density. It was in the shape of a tightly packed block and was very sturdy. Gum B was pink and stringy. It was very thin and flexible. We came up with a hypothesis for the two gums bubble creating ability. If Hubba Bubba is blown into a bubble, then it will be larger than Big League Chew because Hubba Bubba has a stronger consistency and won’t break as easily as it grows.
Our material was as follows; Hubba Bubba, Big League Chew, 1 metre stick, and 2 pieces of tin foil.
The lab began with one of us chewing the gum for 3 minutes, then blowing bubbles 5 times and measuring them to find the average. We did the exact same procedure for the next gum.
| Gum A | Circumfrence |
| 1 | 16 cm |
| 2 | 21 cm |
| 3 | 12 cm |
| 4 | 14 cm |
| 5 | 25 cm |
| Gum B | Circumfrence |
| 1 | 6 cm |
| 2 | 19 cm |
| 3 | 14 cm |
| 4 | 8 cm |
| 5 | 11 cm |
After taking all the measurements we found the average of Gum A was 17.6 cm in circumference and Gum B had 11.6 cm in circumference.
We could then conclude that Hubba Bubba is the gum best for blowing bubbles between the two. This is because the gum was much thicker and harder to chew in the mouth; when blown, it had a thicker consistency and could stretch farther and not break.
Part 2, we tested how far each gum could stretch and how that related to its bubble size. If the gum was able to create big bubbles, then it should also stretch further because it is strong enough to stretch and not break.
We took the pieces of tin foil, stuck two ends of the gum to them, and pulled. With one trial we found that Gum A had the length of 46.1 cm and Gum B got to 82 cm.
We could then conclude that our hypothesis was incorrect. If a piece of gum has a bigger bubble size than another brand, this does not mean the stretchability is larger as well. If it blows a bigger bubble it is because the strength of the consistency is able to hold much more air. The more thin and stringier the gum, the further it should be able to stretch. This data showed that the Big League Chew was stringier, with a softer consistency. Hubba Bubba had a strong consistency that let it be blown huge, but couldn’t stretch as far when pulled.
We also recognized that there could have been some factors that could’ve affected the outcome of this experiment.
To finally conclude, after observing both experiments and seeing the results, our hypothesis should be refuted. Even though the first hypothesis was proven correct, the second one was proven wrong. For both these experiments, the factors listed above could’ve definitely played a role in the success of finding an accurate resolution. From what witnessed with our experiment, the gum stretchability was different when being blown into and being pulled. I think this is because of how long Gum A waited until it was pulled. When we went to pull Gum A, it was super dry and stuck together closely. This could be an explanation for why Gum B was able to be pulled so much farther, it was still soft from freshly being chewed. The results of this experiment were not accurate, we had many factors that were changing the results and the variables. We should have waited the same amount of time before pulling Gum B as we did Gum A. In the end, we did learn that every part of an experiment matters to the results and that we were able to blow bigger bubbles with Hubba Bubba and not have it break.

The novel The Kite Runner, by Khaled Hosseini, has a strong message about humans and their betrayal, guilt, and redemption. It is about a boy named Amir who grew up in Afghanistan and fled the country when the Russians created war. He left behind his servant and his son, his best friend. When he hears of bad news of another friend, he returns to Pakistan to see how he is doing. He finds out his childhood best friend is dead and he should help his son. In the end of the story, he was able to bring the son home to live with him and his wife.
I learned about how people cope with the remorse. Amir left his best friend, the son of his servant, to be raped in defense of him. He watched and couldn’t be brave enough to help. When he left Afghanistan only with his father, he held on to the hope and the happy memories of him and his best friend flying kites in winter days. He held onto the happiness, proving again that happiness can get you through the toughest of times. When Amir left though, he still had the guilt of never acknowledging what happened in the alleyway, apologizing, and having tried to make them leave the house so he never had to deal with the memory again. He traveled back home, through a dangerous and war torn country, to help the son of his best friend and feel redemption from his betrayal; he was able to then forget his guilt after helping the boy. The war torn country itself represented betrayal. The Afghans fought against the Russians, but ended up becoming power hungry. With this power, they betrayed the Afghan people and created a racist and extremist fight against their own people.
This book shows both sides of betrayal. Those who betray others for power. It shows the humans who are selfish, who crave power and control. They may have seen their ethnic cleansing and extremism as the best for the country. It shows a friend who betrayed a close friend. It showed that with betrayal, you can choose to redeem yourself. The Afghans who created another war after the Russians left may not have seen their actions as betrayal. The book shows that reasons for betrayal are not always evident to the person, some may feel guilt with their power over others and some may not. It also has a small representation of happiness. Humans need to be happy, to have good memories, and to care. Without any care, they might not have any motive for actions. The Afghans cared about their country, Amir first cared for himself, then his redemption. Happiness is a light that may let you stay strong in rough times. Rough times could be being inside a tank, escaping your home country to a new country. Happiness is something to hold onto that is there to help you get through an issue.
This story shows different perspectives of the same emotions. It shows how some humans become selfish and may cope with guilt. It was a powerful story that taught me about struggles of those in war torn countries and the perspectives of radical leaders and regular people with guilt.
