For my orthographic drawing, I created three different views of my putt putt boat. I created a top, front and side view of my boat. I created an orthographic drawing because it accurately shows the top, front and side views clearly and more precisely. I was representing a 3d object in 2 dimensions. My three views show how each side of the boat looks in detail and the accurate measurements of the boat. To create the hull, we shaped a piece of aluminum into a “pocket” by using sandpaper to sand…

The ancillary process for methanol production is purification. The aim of purification process is to separate the methanol from any impurities such as water, alcohol, alkanes, etc. Methanol is transferred to storage tanks which is specially assigned for crude Methanol. The Methanol will then be feed to the next part of the operation which is purification. In two different distillation columns, Methanol is purify to achieve the product quality which is required. In the first column, low boiling…

Last week in science class we worked on a lab called the Big Freeze. The objection of the project was to make a cooler and try to keep a block of ice frozen for 24 hours. For my cooler, I used a cardboard box, and put my ice container right in the middle of it and taped it down. Then I put bubble wrap on top of the ice container. After that I put a layer of aluminum foil on the bubble wrap and then put cotton balls and extra styrofoam on top of the foil. The last thing I did was put duct tape on…

Description of the activity: The activity involves a small scale simulation of oil spill clean-up and containment protocol including the use of booms, skimming, and other techniques. The simulation will be performed by filling plastic cups with water, adding oil to the water to simulate an oil spill, and then participants will be given the freedom to experiment with the optimal method for removing the oil from the water or stopping it from "contaminating" other areas by using provided materials…

The noble gases are the group of elements which are like no other elements. The noble gases are the elements grouped as the last group, group 18. These elements, from smallest to greatest atomic mass, are Helium, Neon, Argon, Krypton, Xenon, and Radon. Group 18 wasn't always called the noble gases. this group used to be called the inert gassses. They changed the name of thisi group because they are not always inert, or chemically inactive. the first element in this group is the element…

Temperature and pH will affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different…

The active region displayed in Figure 1 show a larger pore and several smaller pores in G-band. Bright points and several micropores are also visible. This active region was observed from 18:08 UT to 23:38 UT. However, there are three gapes from 18:42 to 19:08 20:21 to 20:47 and 21:59 to 22:26. Figure 1 shows the first image of the time series. Figure 2 illustrates the evolution of the fine structures at the inner part of the granules (i.e. towards umbra) at the pore boundary. Several dark…

〖Na〗^+and K^+channel relationship Figure one shows the temporal relationship between 〖Na〗^+ conductance (g_Na) and K^+ conductance (g_(K )), and the relative changes in the V_m during an action potential. 〖 g〗_Na increased as the V_m moved towards 0 mV causing depolarization of the membrane and started to decrease immediately after the peak of the action potential. Whereas, g_(K ) increased immediately following the action potential peak during the repolarization of the plasma membrane where…

just as curious as George himself. Since the age of five, I’ve been amazed by chemistry (and I didn’t even know what it was). This included everything from why oil and water never mixed together to where my water disappeared to after being unattended. While the interactions of polar and nonpolar molecules drew my attention, I wanted to learn more about how molecules interact with each other, so I joined the AP Chemistry class offered at my high school. On the first day, I was overwhelmed. I…

Since the naming of the dinosaurs in 1842 it has been thought that their metabolisms were similar to current day ectothermic, cold blooded reptiles., In the 1960’s- 1970’s; however, it started to become apparent that an endothermic metabolism (warm blooded, like mammals) is more conformable with new evidence and observations. Originally, predictions on the paleothermometry of dinosaurs was based on the physical performance such as the estimation of running speed from trace fossils as well as…
