A stopwatch was used to monitor how long the reaction took to complete. There are two areas for error by using a stopwatch‚ the first is human error of not being able to stop the timer as soon as the solution changes colour and the second is having to estimate when the solution has fully

as one continuous line‚ the first part of the trend line shows a steep‚ straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover‚ it shows how a reaction at 20°C a slower time for the cross to disappear compared to 40°C and especially 60°C. Both graphs show how temperature has a great effect on the speed of sulfur formation covering the X on the paper. In this graph‚ it shows the relationship between temperature and the rate of reaction

Boeing 747 People tend to take for granted of the technological advancements in today’s society. For every new object released in today there is a story of how it got there. Nowadays to travel long distance‚ such as going cross country or to Europe people are going to need to fly. In 1969 Boeing introduced to the world the biggest airplane at the time. This airplane is called the Boeing 747 and is the reason why people tend to travel comfortably to Europe and other far places. When the Boeing 747

With the rapid growth of technology one many wonder how it is affecting culture and if it is good or bad. In American culture today‚ I see it in both lights. With more and more robots being produced‚ people are starting to be replaced and are consequently losing their jobs. Even a simple production line for making a car is not necessary for human labor anymore. The sense of products being “hand made” is a rare commodity these days. Culturally‚ it effects people by losing their channel of income

experiment was to determine how many disks of spinach leaves float at the end of every ten minutes. Our main focused and question was how using different amount of concentration of sodium bicarbonate would affect the process of photosynthesis producing carbon dioxide. Our hypothesis was we will see more spinach disk floating because they are producing carbon dioxide as time pass by within 40 min and the more sodium bicarbonate we add with carbon dioxide‚ it would affect photosynthesis to produce more

For my science experiment I will be testing if phototropism affects pea plants. The purpose of this is to see how much the growth of the plant is affected by sunlight. Many years ago the scientist Charles Darwin discovered what today we called phototropism. I intend to create my own small experiment except this time I will be using artificial light instead of natural light (the sun). The definition of tropism is "a growth movement whose direction is determined by the direction from which the stimulus

this term can also refer to a rocket engine. Similarly‚ to most engines‚ rockets burn fuel‚ which then turns into hot gas. The engine then pushes the gas out the rocket’s back‚ allowing the projectile to move forward. It is important to investigate how to successfully launch rockets to serve for different purposes. For an example‚ NASA utilises rockets for various goals including launching satellites‚ sending probes to other worlds and scientific research (with smaller rockets). By understanding the

I learned the definition of style‚ how word choice can affect your writing‚ how to use passive or active voice‚ and I now understand how to determine the structure of sentences and paragraphs. Learning all of the factors that go into style really contributed to the 1‚000-word auto ethnography paper and both of the summaries I wrote. I
