Newton’s Laws

 

I’m sure we have all heard of the brilliant scientist Isaac Newton who is famous for his law of gravitation, which was a one of the many brilliant discoveries in the scientific revolution in the 17th century. His law of gravitation was everything in the universe is in some way attracted to each other. We will be looking at Newton’s three laws, videos demonstrating them, explaining why the specific law is demonstrated in the video, and maybe why the law may not exactly apply to the example if it does not.

Newton’s Third Law

Newton’s Third Law put in brief terms is: every action has a reaction. In this video a tennis ball falls off of a table and bounces back up into the air. The ball falling off of the table is the action, the ball bouncing back up is the reaction.

Newton’s Second Law

Newton’s Second Law summed up is the acceleration on an object correlates to the magnitude of force put behind it to put it in motion and mass of the object. In the video there is a softball and a tennis ball both with around the same mass. The softball is flicked and it goes forwards some distance, The tennis ball is then thrown across the ground with more force and it also goes forward some distance. the Tennis ball had more acceleration because it had more force even though it had the same mass therefore the magnitude of force is proportional to the acceleration of the object. However if we were to change the type of material to maybe a 1 lbs rock ball and a 1 lbs paper ball, the acceleration may not be the same due to paper being effected more in an environment with air resistance.

Newton’s First Law

Newton’s first Law, or the Law of Inertia, is when an object that is at rest stays at rest, and an object that is being moved by a force stays moving unless there is an opposing force to stop it. In this video you can see that at first there is a tennis ball that is not moving, it is not moving because an object that is at rest must stay at rest unless a force acts on it. When the ball is pushed it rolls until eventually stopping. But Newton’s first Law states that an object in motion must stay in motion, why does the ball stop if Newton is right? The ball would only have kept moving constantly if there were no opposing forced acting on it. Since the ball was rolling on the floor, the wood caused a force of friction that made the ball come to a stop.

“Lord of the Flies” – island description

seanh2015 on

(a brief description of what the island in “Lord of the Flies”, may look like.)

1) Scar

“between the scar and the sea. There, too, jutting into the lagoon, was the platform, with insect-like figures moving near it.” (39)

2) Lagoon

“A great platform of pink granite thrust up uncompromisingly through forest and terrace and sand and lagoon to make a raised jetty four feet high.” (13)

3) Mountain

“his eyes and followed the jagged outline of the crags up toward the moun- tain. This part of the beach was nearer the mountain than any other that they had seen.” (33)

4) site were Ralph and Piggy find the conch

“Ralph had stopped smiling and was pointing into the lagoon. Some-
thing creamy lay among the ferny weeds.
“A stone.”
“No. A shell.” (18)

5) Forest Where Fire Happened

“The pile was so rotten, and now so tinder-dry, that whole limbs yielded passionately to the yellow flames that poured upwards and shook a great beard of flame twenty feet in the air. For yards round the fire the heat was like a blow, and the breeze was a river of sparks. Trunks crumbled to white dust.” (56)

6) The Conch Location

“The shore was fledged with palm trees. These stood or leaned or reclined against the light and their green feathers were a hundred feet up in the air.” (10)

7) fruit tree

He picked his way up the scar, passed the great rock where Ralph had climbed on the first morning, then turned off to his right among the trees. He walked with an accustomed tread through the acres of fruit trees, where the least energetic could find an easy if unsatisfying meal.

8) coral reef

”The reef enclosed more than one side of the island, lying perhaps a mile out and parallel to what they now thought of as their beach. The coral was scribbled in the sea as though a giant had bent down to reproduce the shape of the island in a flowing chalk line but tired before he had f inished. Inside was peacock water, rocks and weeds showing as in an aquarium; outside was the dark blue of the sea. The tide was running so that long streaks of foam tailed away from the reef and for a moment they felt that the boat was moving steadily astern (Golding 38).

9) Mountain

“Where the pink cliffs rose out of the ground there were often narrow tracks winding upwards. They could edge along them, deep in the plant world, their faces to the rock“(Golding 34).

10) Scar

”Jack pointed down. “That’s where we landed.” Beyond falls and cliffs there was a gash visible in the trees; there were the splintered trunks and then the drag, leaving only a fringe of palm between the scar and the sea“ (Golding 39).

11) Shape of the island

“It was roughly boat-shaped: humped near this end with behind them the jumbled descent to the shore.”

12) Jungle

“Trees, forced by the damp heat, found too little soil for full growth, fell early and decayed: creepers cra- dled them, and new saplings searched a way up.”

13) Ocean

“faced by the brute obtuseness of the ocean, the miles of
division, one was clamped down, one was helpless, one was condemned” (Golding 158).

14) is an island

“This an island. At least I think it’s an island. That’s a reef out in the sea” (Golding 7).

 

 

 

 

Does Caffeine Stunt Your Growth?

Does Caffeine Stunt Your Growth?

A lot of us in our early years have wanted to try coffee but we’re told no by our parents

because if you drink coffee at a young age it will stand your growth and make you short. The

myth that caffeine stunts your growth is a misconception and is not true at all but is still a common

belief. There is absolutely no concrete evidence that caffeine does so, and I will give you a few

reasons why it does not. First off, where did this myth originate from? Why do or did some of our

parents think this myth was true? The misconception that caffeine stunts your growth is from a time

where people thought coffee caused osteoporosis and osteoporosis was thought to stunt your growth.

There are some problems with this theory: caffeine does not cause osteoporosis, and osteoporosis

usually does not stunt your growth. Maybe our parents told us this as children because they wanted to

keep us away from caffeine in general. I think this because coffee is one of the most heavily

researched foods and you would think people would be more informed about it. A study that involved

81 adolescence for 6 years was conducted to compare the bone density of people that take in more

caffeine to people who take in less. Those with high caffeine intake had the same bone density in the

end as those with lower caffeine intake so this should pretty much debunks the myth completely. A

reason why coffee drinkers may have low bone density is because coffee drinkers tend to take in less

milk and other calcium containing beverages. In conclusion caffeine in fact does not make your bone

density lesser and will not make you short.

September Lab Reflections

September Lab Reflection

I chose to reflect of the sunflower crepe lab because it was the best tasting thing we

made this month. One thing that went well was the final product, it was more delicious than I

was expecting it to be. The only thing that went wrong was that we went a little bit over the

time provided because we were having some difficulties understanding the recipe. The thing

that confused the group was which ingredient do we take double of because we were making

the sunflower crepes in groups of 2 in our table of 4 definitely make this again because it is not

that hard to make and it tasted really good. I also chose to reflect on the croissant recipe I was

not present at school the day they were baked unfortunately. I heard they were delicious. What

went well was despite having a major setback we still were not that late for the next block. Our

mistake was we added where we were not supposed to and had to redo the entire recipe

which took around 15 minutes. Another setback was a custard cup made of glass slipped out

of my hand and shattered onto the floor. I had to leave my group to clean up my mess. I would

definitely give the croissants another shot just for the sake of doing it right and actually getting

to actually taste them which I could not originally do because I was absent.

 

 

 

“Secret Life of Walter Mitty” Narrative

“The Secret Life of Walter Mitty” Alternate Ending

 

As Walter faces the firing squad he has a mysterious smile on his face, almost as if he was insinuating his escape, the soldiers are confused and look back viciously, and are eager to shoot him. “Hey! Our guns don’t work!”

“they’ve been tampered with!” Said one of the soldiers.

Walter laughs, and pulls the grenade that he was hiding in his pants the entire time, Walter throws the grenade at the confused soldiers. The soldiers in distraught dive for cover and Walter escapes with a huge explosion behind him into the mysterious war torn city that he would have been executed in…

“Walter why did you throw your wallet into the middle of the parking lot?” Asked Walter’s wife.

“Oh my bad, it must have slipped out of my hands,’ said Walter.

“Whatever, we can go home now we’ve done everything we need to do” said Walter’s wife.

on the way back to the car Walter sees a store with some very nice watches. He notices one specific watch that completely stands out from all the others… Walter finds himself standing over a bomb big enough to blow up the entire building and the criminal he detained who planted the bomb near him.

“Tell me the code!” Yelled Walter, trying to sound as intimidating as possible.

“Why would I tell you anything! Either way i’m dead!”, said the insolent criminal.

Walter knew the criminal had a great point, so he knocked out the criminal with a pipe knowing that he would be no use to him if he wanted to defuse the bomb, he would only be false hope, a distraction. Walter had to figure it out himself. Walter with very little knowledge of bomb defusing aside from some action movies, started inspecting the bomb looking for anything that could help him. All he could find were three wires that were all the same color, “hmm, one and three chance? Those are the best odds I’ve had in years,” Walter cut one wire with little to no hesitation and the confidence of a mad man…

“you’ve been looking at that watch pretty intensely” said one of the watch store employees “if you are looking to buy it today there is a 15% discount,” said another employee.

“oh, ummm, no thanks, just looking around” said Walter.

“Are we finally done here?” Said Walter’s wife as he walked out of the watch store.

“oh course honey,” said Walter.

“whew thank god we’re going, nothing interesting has happened today, I need a nap,” said Walter’s wife in a whiny tone.

“of course,” said Walter as he was blankly staring at a very uninteresting puddle.

“Walter you’re making that funny look again, what is going on in your head today?”
