Osmosis And Shuttles: A Short Story

A system is Material moving most stable when it has reached equilibrium. A out of the cell system will tend to go to equilibrium (lowest, accessible energy state) in the absence of added energy (Figure 2).

The reasoning behind this experiment is the examine whether the rate of osmosis is changed due to a change in temperature. It was hypothesized that the rate of osmosis will increase as the temperature of the sucrose is increased. The rate of osmosis was tested by using the different jars full of different temperate water and testing how high the water rose on an osmometer over a span of 20 minutes. An osmometer is a tool used to measure rates of osmosis. The different temperatures tested on a sucrose solution were 5 degrees Celsius, 20 degrees Celsius, and 37 degrees Celsius. Rates of osmosis were higher in the hot water than in the cold water and control. The results showed that the rate of osmosis increased as the temperature increased, henceforth the hypothesis was supported. In conclusion, the experiment showed how changes in temperature affect the rate of osmosis.

It was still about five hours until our flight and Alfred looked starved after going without food for an hour. We found a parking spot to abandon his car in until we came back from the trip. The bus to the terminal took a while, but it did not justify waking up so early for the 11 o’ clock flight. It wasn’t until we got inside that I found out just how much the airport has changed. We checked in our luggage and printed out our tickets at this machine that scanned our passports. We went up an escalator to find our gate, but before we could get to it there was this huge line we had to go through.

8 hours. Finally, over, of painstakingly mopping rugged floors of the crowded international terminal. Not how a regular 21-year-old woman should spend her time. Now, just cramming myself in my old Volkswagen and driving for hours under the dark and eerie atmosphere to a spine – chilling home ...

It was almost 4am and we had slept in the cold LAX airport on black and while marble floor. Very comfortable and accommodating. At this point a cardboard box on a heating grate in New York would be the Ritz Carlton. Jamie and I stared at each other coldly, hating each other, damp sweat and anxiety poured over us. Silence. We just want to get out of here. "This sucks." Was a common response to our deliriously back and forth conversation as we tried to keep our spirits up.

The floor rumbled fiercely beneath my feet. A cold jet of air brushed against my leg. My head was push against the window, viewing the taxi line filled with airliners. The roar of the engine grew violently. I could feel the acceleration tuck me back into my seat. The runway seemed to slip underneath my feet, briskly increasing in speed. Then, with a sudden lurch, the nose banked upwards. Liftoff. A sudden thrust of gravity spiked across the cabin. The vertical speed rose steeply as the tail plummeted sharply. The airport slid out of sight as the aircraft approached the lush cerulean Gulf of Mexico. I glanced back at the albicant, old cabin. I looked back at the window. The waters of the gulf of Mexico darkened along with my nerves.

Kevin grit his teeth. His hands strangled the arms of his blue leather seat that were embroidered with white thread. Fear oozed from every pore within his body. His body tensed as we felt the engine roar, saw the turbines spin, and runway come to life. As the plane’s thrusters kicked in, Kevin shut his eyes, but I didn’t. I stared through my window and watched the runway lights gradually merge into a single line of fluorescent orange. Before I knew it, I was gazing upon Philadelphia, hundreds of feet in the air, illuminated by the light of an afternoon’s sun. Our destination, the Marine Corps Recruiting Depot.

As soon as the door opened, the heat hit me. It was like putting a hot iron in front of my face. But it felt even worse as there was a slight wind which pushed the heat towards me. My body was surrounded in a blanket of heat and I even started to sweat slightly. My uncle told me to wait by the lift as he went to collect the car so I wouldn’t have to walk as far and drag my suitcase along. While I waited, I took time to look around at the surroundings. I could see mountains which stretched towards the clouds and the airport behind me. There were a vast number of people walking around from their flight looking drowsy and with no energy. The frequent red double-decker bus also came and a few planes flew above my head. I didn’t even have to look, but I could hear the planes departing and arriving. The planes all looked the same in the sky, big and white with some sort of logo. During the wait, I took a few steps to take away the cramp. Although I had trainers on, I could feel and see that the floor was new. The concrete looked

The flight deck is a beautifully orchestrated ballet. All around me the sound of people yelling and jets turning fills my ears. I’m drenched in sweat. I feel alive. The smell of saltwater and jet exhaust fills my lungs and in that moment I’m

As the flight attendant announces final calls for my plane ticket, I sit anxiously for the plane to depart. The attendee speaks loudly, “Welcome aboard Flight #3102. We will depart from DFW airport and arrive at Bora Bora airstrip in approximately eighteen hours and ten minutes.” My stomach starts to turn. I can hardly wait to arrive in a place that one could only dream about.

This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved.

I woke up from my nap when I felt a light tap on my shoulder by my brother, Alex. He told me that it was time for the plane to begin its descent so I gathered my belongings and adjusted my seat until it was upright. As the airplane began to descend, I was filled with excitement and enthusiasm. I could feel so much energy rush through my veins as my ears popped and I finally heard the flight attendant say, “Ladies and gentlemen, welcome to the Singapore Changi Airport!”

Osmosis has long been taught to students, especially those in high school or introductory science classes, as a simple variation of diffusion. Because osmosis is the first of many natural phenomena understood by students, it is important that it is understood correctly. This however, is not the case. In fact, discrepancies exist between how osmosis is taught and understood between physics and chemistry or biology [1]. Moreover, since the agreement of the real processes involved within the physics community back in 1951, no progress has been made with osmosis in biology and chemistry education [2].

I can see it through the open windows of the buildings, standing there, tall, shiny gray and with the American flag painted on the front. My hands are sweating and my heart is racing. I’ve never felt this way before, but I remember why I’m doing this and that after all I did to get here I can’t back down now. I step out of the room in the hall. I can hear the reporters and the people outside. They scream my name and the camera’s flash. I push open the door and I’m confronted with not only the hundreds of people but with my destiny. The closer I get to it, the more it seems to grow, like a weed in my mother’s garden. By the time I get to the loading ramp and stare up at it, I can no longer tell where the spaceship ends and the sky begins. The beams of sun reflect off it and blind you. I have to squint just to see my family--and my future
