Water Wheel Work‚ Power‚ and Efficiency Pre-Lab Preparation: Purpose: The purpose of this lab was to create an efficient water wheel that would produce a productive time in lifting the cup of nuts and bolts that was attached to the pipe used in rotating out water wheel. The more efficient our wheel was the better the time we would have in lifting our cup. We were then able to observe the work that was needed to turn the axel‚ the time that is taken to bring the cup of washers to the axel‚ and

Lab Title: "The Effect of Salt on the Boiling Point of Water" Lab Question: How does adding salt to water affects it’s boiling point? Prediction : In this paper‚ a newly proposed model based on solvation between pure solvent and salt for prediction of salt effect on vapor–liquid equilibria is presented by using only the vapor pressure depression data of pure solvent+salt systems that compose the mixed solvent with salt system Materials : 200 mL of distilled water‚ 2 beakers

Water Testing Lab Conclusion In this lab‚ chemical tests were used to check for the presence of calcium‚ chloride‚ and sulfate ions in water samples. To do this‚ the testers started with five samples: a reference‚ a sample of only the chemical being tested for‚ a control‚ distilled water‚ two home water samples‚ and a school water sample. To test for the ions in the water‚ a chemical that would react with the ion and create a precipitate was added. If the precipitate was not easily visible‚ a

this hidden pond a few blocks away from my house. I was a kind of creepy old pond. If you ever saw it‚ you probably would not want to go there. However‚ it was a sunny afternoon‚ and I decided to jump over the gate and walk towards the pond. One thing you have to know is that the reason why it’s a hidden pond‚ is because‚ it almost looks like its a small forest when you look at it. It’s surrounded by so many trees. It wasn’t until I walked through the mini forest‚ that I found this pond. There was

Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution

The first lab we did was overall fascinating. Each station had something different to offer and revealed results that I would not have guessed. The exercise that profoundly stuck out to me the most was the “water tank‚” lab. The procedure of the lab was to shoot a red laser beam into the tank of water from three different directions. I first shot the laser from above the water surface‚ then from below‚ and finally from the side of the tank. Interestingly enough‚ each direction‚ the laser would bend

Conclusion: Category 1: Momentum was found that after the collision was less than before the collision by 10%. This was not what has been expected‚ so the difference was fairly significant. This happened because of friction‚ when the two pucks collided‚ they have lost a bit of their momentum‚ so the momentum after the collision differed. Kinetic energy differed more than what was expected‚ it was significantly less after the collision‚ the difference before and after the collision was 63.7%‚

The purpose of this lab was to model the significant differences in density that oceans experience when glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh

Jane Watson First Essay – Memoir The Pond Incident When I was a child I was always told about how strong I was. This was a big deal since I wasn’t even supposed to survive due to having the umbilical cord around my neck. The doctors told my parents that if I survived the first seventy two hours‚ they would see how much brain damage I had. It wasn’t IF I would have brain damage‚ but how much. I was to be one of the lucky ones. Not only did I live‚ but I didn’t have brain damage that anyone

Lashe Dunbar November 30‚2013 2nd Hour On Golden Pond Erik Erikson’s theory of psychosocial development is one of the best-know theories of personality in psychology. Erikson believed that personality develops in six individual stages. In the movie On Golden Pond‚ each of the characters display different psychosocial stages. Norman Thayer shows Erikson’s last stage‚ integrity vs. despair. In the movie Norman is bitter‚ and is pessimistic. Many times in the movie he states how old he is‚
