Science experiments

scientist force them to eat and drink just for experiment. “For example: forcing dogs to inhale cigarette smoke did not show a link to lung cancer; Flossing, an arthritis medication, tested safe in monkeys but caused deaths in humans; and the recalled diet drug fen-phen caused no heart damage in animals, while it did in humans--just a small sampling of volumes of examples.” (NEAVS-- New England anti-vivisection society) Replace animals from experiments doesn’t mean that we put human beings at risk

The aim of this research was to investigate the Cumulative Representation of Uncertainty. The researchers recruited 25 graduate students from Berkeley and Stanford (12 men and 13 women). The experiment was conducted on a computer. In trial, the computer exhibited a possible event (for example, 25% chance to win $150 and 75% chance to win $50) and its expected value. The display also included a descending series of seven certain outcomes (gains

Discussion Hypothesis 1: Experiment 1, I accepted my oil hypothesis because the oil formed a thin even layer on top of the water and resumed after I stirred it up with the wooden stick. Vinegar hypothesis: I accepted because the vinegar was only identifiable by smell. Laundry detergent hypothesis: I accepted because the laundry detergent contaminated the water by changing the color to greenish blue and formed bubbles. They all had an effect on either the smell or consistency of the water. The detergent

My love of being in a laboratory started with my increasing interest in science when I was a child. Being from a single parent home, we did not always have money to purchase toys or do activities; so most of my younger days were spent outside and in the kitchen. During the daytime, I would catch insects, frogs, small fish in the stream behind our home, or help my neighbor on his farm. My neighbor taught me various things about the forest; he showed and named all the trees, edible and poisonous plants

Abstract The following is an experimental proposal that exams the relationship between stress and the effect of a college student’s health. The following hypotheses for the study is that stress does affect an individual’s health. The study consisted of thirty college students (n=30) in total, fifteen of these students (participants) were assigned a control group while the remaining fifteen students were put in an experimental group. The researchers recorded the results of each college student’s

Discussion The results of this lab helped determine which tools are best to measure different objects. In Station 1, a yellow metric ruler, an orange metric ruler, a wooden ruler, and a measuring tape was used. The tool with the highest degree certainty was the orange metric ruler. This is because the orange ruler had tick marks for each 10th(0.1). The tool with the lowest degree of certainty was the measuring tape because it kept moving and it was difficult to keep it straight. For Station 2, a

Hypothesis: It is an expectation that is made based on limited information that explains what may happen in the experiment or trial. For instance, when a scientist expects a hypothesis they are obliged to make a prediction of what will happen due to what variable and give a justification. 1) Reliability: This is the general consistency of measure. At the point when researcher gathers information they need to make sure that the information they collect is reliable by repeating test numerous time or

Essay Prompt: Describe a teacher or course assignment that has had the most impact on you and why. Taking the temperature of boiling water changed my life. It wasn’t until eight years after participating in a simple, yet elegant, marine science lab experiment that I realized its full impact on me. It had infiltrated my life so quietly that the effect had gone completely unnoticed. At least consciously. Unconsciously, as I look back, there were loads of little signs that something was different after

When working out what is the best beverage to help benefit your healthy lifestyle? Is water the best or is a sport drink better. Gatorade has been around for recent decades, but what real benefits does this have. Are sports drinks affective or they part of a health fad squeezing money out of you. The question at hand is if sports drinks are vital for hydration or a waste of money. Addressing the real question of what is in sports drinks that actually help improve hydration or is it just sugar packed

freezing popcorn yield more popcorn? Project Design Plan. This scientific experiment is to gauge the amount of kernels popped when the storage temperatures of the kernels are changed. Does freezing popcorn kernels for 24 hours yield more or less popped kernels than popcorn kernels stored at room temperature? By performing this experiment we can decide how to maximize our food potential. We will purchase six identical brands of popcorn from the local food
