Hypothesis: The atomic mass of the pennium will be the average of the average masses of a pre-1982 penny and a post 1982 penny.…
As you can see from these photos you tried rolling your marble down single run. You found that the marble would roll off the table. To solve this problem you added lots of blocks to the end of the run but this meant that the marble could not travel along the run as you had blocked up the wrong end and the marble got stuck down the first block you put it in.…
In the study of Chemistry, we encounter very large and very small numbers. For example, the size of a molecule or thin layer of molecules is very, very small and difficult to measure directly.…
Purpose: Can the penny hold more drops of water or more drops of the MYSTERY liquid? Research: Cohesion- The state of sticking together. Pennies can hold more water because soap reduces the cohesion of water and the water molecules break apart and can't stay on the penny.…
Dr. Lederman uses a metaphor of a soccer game with an invisible ball to show the process by which the existence of particles is worked out. This metaphor is useful to get a sense of the experience of a particle physicist as he or she conducts his or her experiments in the particle accelerator. This chapter Dr. Lederman gives a brief background story of what led him to particle physics.…
The whole point of this experiment was to create gold that wasn’t the colour gold. The aim was to find out how a variable amount of sodium citrate would change the colour of a gold solution. Meaning the hypothesis was: if more sodium citrate is added the nano particle size will increase and the colour of the gold solution will move towards the red end of the spectrum.…
10. ____ What was concluded about the structure of the atom as the result of the gold foil experiment? (1) A positively charged nucleus is surrounded by positively charged particles. (2) A positively charged nucleus is surrounded by mostly empty space. (3) A negatively charged nucleus is surrounded by positively charged particles. (4) A negatively…
Take 2 photogates and place them 10 centimeters apart, along the edge of the table. (d) The photogates are instruments that will time the marbles speed.…
The first step to conduct this experiment is to set up your ramp, whether it is a pool noodle or flexible pipe insulation. Adjust the ramp to the correct height you chose for this investigation. Next, place the 4 textbooks exactly 84 centimeters from the wall. Then place the cup exactly 40 centimeters from the 4 textbooks. Now it is time to start the actual experiment. Take your marble and place it at the top of the ramp. Let the marble roll to to end of the ramp and record whether or not the marble landed inside of the cup. Repeat these steps adjusting the height of the ramp as you go depending on where the marble lands. The data was used to determine what height was the best for the marble to land inside of the target cup. The data was analyzed by comparing the different heights to the number of times the marble landed in the target…

Rutherford is a Physicist, Scientist. Ernest is also known as the world’s first successful alchemist. Ernest Rutherford was the first scientist to explore into the structure of the atom Unlike many people, Rutherford was not very known for his achievements like the Gold Foil experiment, which helped prove that electrons orbited the nucleus surrounded by empty space.…
“Hills Like White Elephants”, a short story by Ernest Hemingway, presents many interesting insights into relationships between men and women from the era when it was written. During the 1920’s, an era referred to as the Roarin’ Twenties, women were slowly progressing out from their stereotypical household roles to lives of entertainment and partying. In this short story, Hemingway's characters reveal the lingering differences in stature between men and women in this period. Hemingway, in this story, provides detailed descriptions and well thought out dialogue between his two main characters, an American man and a girl called Jig. The dialogue in the “Hills Like White Elephants”, allows the reader to understand the interactions between men and women…

Arthur Miller is mostly known for his connections to Marilyn Monroe, the United States’s national sexual icon through the fifties and sixties. However, while many recognize his work, they do not recognize the author behind the work. Born in Harlem, New York in 1915, Arthur Miller attended the University of Michigan before moving back to New York to write stage plays that have engaging connections with the working class. Through his many plays which have reached national recognition, his works have mostly been centered around the social and psychological dimensions of his own characters with themes of individual morality that is influenced by social pressures. Miller’s political ideologies lodged their way into his various works through themes…
