Science Experiments Essay

hypothesis was If we poured the water on the tissue then the thickest one will have the least amount of leakage. Which we had believe that scott would have the least amount of leakage but in order for us to figure that out we has to experiment it. Before we started our experiment I had many questions about tissue who made it, what made them want to event it. I had so many questions so me and my team had came up with a idea to find the history or facts about tissue. So we had found the history…

reaction as well as the time it takes for each change to occur and the temperature at which each reaction occurs. The amount of each reagent used should also be recorded and the expected yield should be calculated as well as the percent yield for the experiment. Then an analysis of the final product using proton NMR as well as IR should be performed to determine the purity of the final product (melting/boiling point can also be used) and if possible any possible side products that may have been…

replicate the results of the original are discussed. The independent variable was the verb used in the critical question to describe the collision; one condition would be ‘smashed’ and the other would be ‘bumped’. The dependent variable of the experiment was the speed that the participants estimate the vehicle…

The four experiments performed by Bhalla, M., & Proffitt, D. R. (1999) addressed two main research ideas. The first idea was focused on demonstrating that changes in physiological potential in a variety of contexts affect the conscious awareness of slant. The first 3 experiments showed that conscious slant overestimation is increased by the reduction in physiological potential as a result of (1) carrying a heavy load, (2) becoming fatigued by running, (3) being less physically fit, (4) and/or…

In operating my research question which is stated as the following: Why the process of permanency planning work in some states and not in others? In listing variables; age, gender, race, kinship/non-kinship, and permanency planning. My independent variable is permanency planning, dependent variable is the age out process including the long and short term effect of success in life. The mechanism is permanent placement of the child. I will gather participants who related to my research question.…

Does Strength Training Exercises Help to Reduce Stress Among College Students? How stress is experienced and tolerated varies by all individuals. The purpose of this study was to assess if engaging in 2 days or more of strength training exercises results in lower stress levels among college students at the University of Central Oklahoma (UCO). After a careful review of the data the hypothesis was that those who engage in 2 days or more of strength training exercises would experience lower…

The purpose of lab was to see how a heart looks/works on the inside and how the flow of blood travels through the body. This lab relates to a lot of what we studied in class pretty much the whole cardiovascular system and how it works, like its functions of transporting nutrients, oxygen, and hormones to cells throughout the body. I worked on this lab by myself and it took about one full class period and about one hour outside school to complete this lab. I studied the heart and discovered…

Conclusion The overall results support the hypothesis. The experiment involved soaking 20mm (±0.5mm x 2) apple cores in 10cm3 (±0.5cm3) of saline solutions in 0%, 1%, 3%, 5% and 7% concentrations for 1800s (±0.3s (human error)) and comparing the initial masses (g±0.01g) with their masses after soaking (g±0.01g). There was an outlier in the 13% mass change of the apple core after soaking in 7% saline solution, as shown in Graph 2. However, this outlier and the general trend of the data support…

by scientists now and in the past, dating back to the seventeenth century. The scientific method consists of observation, measurement, and experiment, and the creation and testing of hypotheses. There are several steps and different components to the scientific method that will (hopefully) answer the scientists’ questions, by the completion of the experiment. There are countless different reasons as to why a scientist would use the scientific method, but one area of research that is…

continuously changing concept of inheritance. In the future our ideas about inheritance will be different by cause of them changing in the past, the scientific method proves it, and new discoveries may be made. Our ideas about science are constantly evolving. An example of science changing is radiation being used to treat cancer. In the early 1900s, radiologists would test the strength of the radiation before administering it to patients. This led to radiologists discovering high radiation…
