Today, because of the absence of our captain Tsuyoshi Henry Nakajima, Rebecca Merson, Patrick Macellus, and David Misiaczuk and I worked out an awesome experiment. One of our friends, Rebecca, had to leave earlier so it was sad that she could not see what we had discovered.
We started our experiment by getting suitable equipments. We had two thermometers to measure the temperature of two cups of water (one is super hot while another is super cold with ice). Then, there was an equipment introduced to all of us. It was called thermocouple and it was a senor for measuring temperature. It consisted of two dissimilar metals, joined together at one end. We put it into the two cups and looked at the temperatures of the two cups. The temperatures are measured in Fahrenheit. It was our first experiment too. After about two minute, we observe the temperature of the cold water was lower while the hotter water was higher. Before we had our second experiment, we took out the thermometers and had another observation of temperature change. The temperature of the hot water changed from high to low (about 11 degrees). As for the cold water, there was no observable change. Then, a new equipment was introduced and it was called Strobotac 1531. The 1531 Strobotac electronic stroboscope included a strobotron lamp and reflector assembly, an electronic pulse generator that controlled the flashing rate, and a line-operated power supply. It was a small portable flashing-light source used to measure the speed of fast-moving devices or to produce the optical effect of stopping or slowing down high-speed motion for observation. When we turned the number to 3800 rpm (rotation per minute), the light was shining quickly. At that moment, the temperatures were discovered. We had 129 degrees for hot water and 34 degrees for cold water. We came up another observation was the light would shine slowly if we turned the number into a small value. Our last experiment in the day was turning the number into 350 rpm. What we had found out was the temperature of hot water became 150 degrees and 38 temperatures for cold water. Our conclusion was the smaller the number of rpm, the higher temperature of the hot or cold water would be.
Today, three or four of us got a great work done. We were looking forward for working this experiment successfully to the high school students we would visit on December 6. We named this experiment as the thermocouple experiment of an output. Before we left, we cleaned up our tables and stinky places. Last but not the least, we all wished together a great Happy Thanksgiving Holidays.
