The null hypothesis at the inception of this lab stated that the breathing rate of a gold fish would not be effected with decreased water temperature around it. The alternate and working hypothesis however stated that decreasing the water’s temperature will decrease the goldfish’s breaths per minute. After preforming the experiment, my results support my original hypothesis as the fish’s breaths per minute did drop when the water temperature lowered. In my group’s experiment, the fish’s breathing rate stayed constant after only decreasing the temperature by 5 ◦C, the breathing rate then plummeted once the water temperature was at 10 ◦C. As a total class, the experiment further supported the hypothesis with the breathing rate per minute dropping
The purpose of this experiment was to identify which brand of mint gum holds its flavor the longest. The four brands I chose were Orbit, Trident, Ice Breakers, and Wrigley's Doublemint My hypothesis was that Trident brand would last the longest and Wrigley's Doublemint would last the shortest. I did not use any people in my test. I chewed the same amount of gum at a time and the gum was all the same flavor, mint. All the gum was bought at the same time from the same store. I chewed the four brands of gums between periods of time. When chewing, I timed myself with a stopwatch. When I believed the gum ran out of flavor, I stopped the timmer and recorded the time. My hypothesis was incorrect. Instead of Trident, Orbit lasted the longest. However
...-value indicate that the null hypothesis cannot be rejected and the presence of tobacco in the Goldfish water may not have had an effect on the metabolism of the fish. These results indicate that there may not have been an effect in exposure for 10 minutes with a very slight amount of tobacco present in the water. For future experimentation, the concentration of tobacco, medium in which the tobacco is delivered, or exposure period prior to recording data may have provided us with different results. Beside the experimental factors, the numbers may have also been skewed in the presence of two outliers in both the control group and experimental group. To identify which fish may be the outlier or to offset the effect of an outlier, it may be beneficial for future experimentation to test each fish individually to increase the sample size.
For this experiment the null hypothesis is that the intensity of the step rate test (High and Low) has no effect on the persons’ heart rate and recovery time. While the alternate hypothesis is that the intensity of the step rate test (High and Low) has an effect on the persons’ heart rate and recovery time.
Understanding other people’s perspective is vital when it comes to making someone a more informed and a more sympathetic person. For example, in politics, there are two main sides; the democrats and the republicans. These two sides almost never see eye to eye, but when they see from the other’s point of view, an agreement can be made.
Over the observed fifty seconds, there was a consistency among the temperatures. Without a calculated percent error, we are able to assume the average temperature was twenty-six degrees Celsius. There are factors that could have caused error to arise in our data collection. One factor could be that the temperature of the room was not consistent throughout the room. Another factor may have been the performance of the thermometer. The grasp in which the thermometer was held for procedure B may also be a factor.
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
Introduction: The novel Saving Fish from Drowning by Amy Tan follows the hapless journey of twelve Bay Area tourists destined for Burma, accompanied by the ghost of their dear friend Bibi Chen, who died under “mysterious circumstances” just before the departure. The journey continues in a downward spiral until eleven of the tourists go out on a misty lake one morning and disappear. Miss Chen, the omniscient voice of the book, is caught between two worlds and is along for this journey. It isn’t until the end of the book that readers realize many events that occur are actually a metaphor for human relations; and the central theme is that the line between reality and fantasy can be tricky to discern, and things can be vastly different from
A poem without any complications can force an author to say more with much less. Although that may sound quite cliché, it rings true when one examines “The Fish” by Elizabeth Bishop. Elizabeth’s Bishop’s poem is on an exceedingly straightforward topic about the act of catching a fish. However, her ability to utilize thematic elements such as figurative language, imagery and tone allows for “The Fish” to be about something greater. These three elements weave themselves together to create a work of art that goes beyond its simple subject.
In conclusion, the title and context of the article are clear, and appropriately match the hypothesis of the authors. There is consistency between the objective of the experiment and its relationship to science. This writer found some issues in the overall presentation of information, in that the text lacks smooth transition, and was difficult to read and follow.
The hypothesis to this experiment is "if you place a plant under water in direct sunlight, then it will produce oxygen bubbles." In this experiment the independent variable where the plant is placed. The dependent variable is the water the plant is put in. Your controlled variable would both be the type of water used and the type of plant used. The conclusion to this experiment would still ben your hypothesis because its true which is " if you place a plant under water in direct sunlight, then it will produce oxygen bubbles." The only flaws in this experiment were that they used the same type of water and they did not try any other water. I believe that this experiment is
Within the target site of the experiment, researchers wanted to answer their hypothesis; hypothesis was that increased police
Living organisms all need energy to carry out their life processes. Respiration is the chemical process of releasing energy from glucose, and in the case of aerobic respiration, in the presence of oxygen. Gas exchange is the physical process by which the oxygen n is absorbed from the air and into the blood stream and carbon dioxide is released.
Goldfish are typically trouble-free pets for all the family to enjoy. Goldfish are one of the easiest of all fish to keep, but if they are to be kept in an aquarium you must remember that they are totally dependent on you for their welfare. A well cared for goldfish can live for eight years or longer.
Although it is impossible for humans to breathe underwater, what if it was a possibility? The human anatomy would need to change in order to support the same anatomy that allows fish to swim and breathe underwater. All fish have gills. Gills are tissues which consisting of filaments. These filaments have capillaries that allow the exchange of oxygen and carbon dioxide, acids, and ammonia. The gills are located on either side of the pharynx. “How Fish Breathe Underwater” states, A fish breathes by taking water in through the mouth and forcing it out through the gill passages (www.wonderopolis.org/wonder/how-do-fish-breathe-underwater). According to Difference Between Gills and Lungs, Gills are able to diffuse excretory products, but lungs are
Fish and shellfish are an important part of a healthy diet. Fish and shellfish have high-quality protein and other essential nutrients, are low in saturated fat, and contain omega-3 fatty acids. A well-balanced diet that includes a variety of fish and shellfish can contribute to heart health and children's proper growth and development. Thus, women and young children, in particular, should include fish or shellfish in their diets due to the many nutritional benefits.
