What Affects the Rate of Evaporation? Aim * To find out if changes in temperature‚ draught and surface area of water open to air affects the rate of evaporation through the water. * To safely check if these variables change the rate of evaporation * To complete all the experiments in the short period given Prediction * I believe that a raise in temperature will speed up the rate of evaporation in the water * I believe that a larger surface area will speed up the rate of evaporation

didn’t have a say in whether they wanted to or not. Slavery did give the economy a boost‚ mostly in favor of the wealthy. Not everyone could afford to own or buy a slave. Slavery did have some negative effects in the south since not everyone was wealthy enough to own slaves or own a big plantation. Small plantation owners did not really benefit from slavery. Since big plantation owners had more hand to do their work the more they produced. Compared to the small plantations who didn’t have as many

The effect of water and fertilizer on corn seedlings Biology 1108 Lab Section November 7‚ 2012 Abstract The effect of water and fertilizer on corn seedlings was examined. It was hypothesized before the experiment that enough water with sunlight and air should make the plants grow healthy. It has to do with photosynthesis. Fertilizer is also going to make the plants grow much faster; this is because of the nutrients in it. The experiment took about four to six weeks to complete; it took some

Individual Project Unit 2 Experiments In this individual project we were asked to conduct three experiments. The three experiments I chose to conduct were Experiment 1‚ Experiment 2‚ and Experiment 4. I have documented my findings for the experiments that were done. In Experiment 1‚ I was to rub my index finger gently over a piece of very coarse sandpaper for a few times. Then‚ I was to rate its coarseness on a scale from 1 (very soft) to 7 (very coarse)

Throughout history‚ the nomadic Mongols has been known to be one of the most brutal and vicious civilizations to occupy the face of the Earth. But though have been known to be a cruel group of people‚ they have shaped many civilizations and aided in the advancements of science and technology. This is evident in regions such as China and Russia. They are both affected similarly where the Mongols impacted them to increase their activeness in trade. Another constant is that both of China’s and Russia

The past three weeks I can say that I have learned quite a lot‚ I never really thought I could understand what entailed through organized crime. There are many different attributes that were involved to form organized crime. Without knowing exactly what those attributes are you would never be able to figure out what it takes to organize crime or even get why they call it organized crime. I would say to myself why do these mafia and big groups put so much time and effort into making sure that there

The end of World War II left Americans confused about what their future held. Soldiers returned home to reclaim their occupations before the war. This led to many women losing their jobs and freedoms that they obtained during the war. Legislation of nuclear warfare became imminent and citizens were unsure of their safety. Although there were many uncertainties about the future of the society at the end of World War II‚ the ending was very beneficial to the United States of America. It led to

Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall
