Solar Cell Experiment Aim: To see how individual factors affect the output of a solar cell. Factors affecting the output of a solar cell: This experiment is going to be performed in the confines of a school laboratory, and so the complexity and cost of the experiment(s) should reflect this. However, to see how different factors affect the solar cell output, I will need to perform at least two experiments. The question is, which ones? · Distance from the light source will affect the
ELECTROCHEMICAL CELLS Purpose: In this experiment, several different half-cells will be prepared and connected to find the voltages generated. Also, the concentration will be change in one of the solutions to see how this affects the cell potential. Thirdly, the electrical potential of a cell containing silver and silver chloride will be measured. Lastly, a cell containing copper (II) and ammonia will be constructed. The potential and the Nernst equation will be used to calculate the formation
Beetroot Experiment We are trying to find how the temperature affects the rate at which the anthocyanin pigment leaves the cells, and at what point does the call wall melt. Beetroot Experiment =================== Task ---- We are trying to find how the temperature affects the rate at which the anthocyanin pigment leaves the cells, and at what point does the call wall melt. Please note the two results highlighted found in "test 4" have not been included into my results, as
about a new subject and some of those ways are cruel, inhumane, and plain torturous. There is no hiding the fact that there are unethical experiments happening everyday all throughout the world, but there is also no hiding the fact that some unethical experiments have helped researchers and scientists significantly. Everyone’s who acts on these unethical experiments have the goal to be able to understand the world and how everything fits and works well together. The lab rats or test subjects pay a price
An ongoing conflict among the human species is that of animal cruelty, whether it be by scientific experiments, tests, or research. I frequently wonder, do the individuals performing these atrocious tasks ask themselves if what he/she is doing is ethically correct? I believe that it is not right to treat animals in such an inhumane manner, but to treat them as our own kind, for they are clever, spirited beings. These helpless animals cannot defend themselves against abuse. In my opinion, it is morally
According to an article by PETA, “experiments on animals are cruel, expensive and generally inapplicable to humans” (PETA 1). This shows how not only many laboratories and companies that use animals in their experiments are wasting money and time, but also wasting countless lives of animals. As a human, one does not have to suffer through unconsenting pain because no one would
accounts of medical human research date back to the development of vaccinations in the 1796 (Stern, 2005); although, it is understood that studies to further understand the human body were conducted centuries before this. Through these vaccination experiments, profound evidence emerged that would drastically impact and help global populations (Stern, 2005). Unfortunately, in other cases, results were detrimental and torturous to the human subjects. These kinds of studies often focused on the progression
Laboratory experiments on animal Jack stumbled upon an article, about how animals are being abused, tortured and killed for the things we commonly use in our household. Written on the article is how a female dog, named Libby have gone through in the hands of researches, it says there that pharmaceutical companies have paid the laboratory to infect animals with worms, fleas, and ticks and smear toxin in their skin to test animal companion products, Imagine how animals are being treated in the confines
Experiment to Find the Reaction of Potato Chips in a Salt Solution Aim: to find a reaction of potato chips in a salt solution. Hypothesis: I predict that the potato will change in mass. The difference will occur in accordance to the difference of concentration of the salt solution each potato chip is submerged in. The cause of this change in mass is called osmosis. Osmosis is the movement of water through cells in plants. I make my prediction on the pretext that water diffuses from
of which has become a big controversy in our society is the use of cell phones while operating a vehicle. This essay will focus specifically on talking on a cell phone while driving and how to safely and accurately get results. We will look at why it is important to have a control group during the experiment, how the subjects should be assigned, and the ways that we can make the only difference in the experiment is the use of a cell phone. So, why is it important to have a control group? A control
Animal Testing Animal testing is the act of conducting experiments using non-human animals to control variables in investigations. The variables may affect biological systems or behaviors in experiments. It is research done to test drugs, medicine, cosmetics, food additives and pesticides for the benefit of humanity. Every year, up to 100 million animals may be experimented on for animal research. Animals range from mice to chimpanzees, but most frequently used are guinea pigs, hamsters, amphibians
The Effect of Soaking Raw Potato Chips in Various Salt Solutions Aim In my Experiment I hope to discover the possible concentrations of potato cell sap using osmosis. Osmosis is the passage of water molecules from a weak solution into a stronger solution through a partially permeable membrane. We hope to achieve this by doing four experiments using distilled water in one test tube and different concentrations of salt water in the other test tubes. Once done, we will measure the change
today’s society is whether or not animals should be tested for purposes of human-based research. This research can determine the results of new products, test human health and evaluate the safety of consumer and industry products (Humane). These experiments are irrelevant to humans. Animals should not have to suffer for the benefits of mankind. Vivisection is cruel and inhumane, poorly predictive of human outcomes and is not the only method available to discover possible repercussions. Vivisection
consequences. The use of animals in experiments at labs that are funded by the government has increased 73 percent in the past 15 years, according to a new study conducted by PETA. The study, in the Journal of Medical Ethics, found the number of animals tested increased from 1,566,994 in 1997 to 2,705,772 in 2012 in testing by the top 25 institutional recipients of National Institute of Health grants.” stated CBS News. With each year, the numbers increase these experiments range from experimenting new
killed after the experiment or due to the experiment. They often suffer from food and water deprivation, and forced chemical exposure. Most of which are not protected by the Animal Welfare Act (AWA). Therefore, animal testing is wrong and inhumane, and should be banned from further experiments. There are many different types of animals that are usually tested. Most include rabbits, rats, mice, cats, fish, and many more. Many of these animals are used for different experiments and suffer in different
In this experiment I am going to investigate how different concentrations of sucrose solution can alter the process of osmosis on a potato chip, and in what way it does this. Osmosis Aim: In this experiment I am going to investigate how different concentrations of sucrose solution can alter the process of osmosis on a potato chip, and in what way it does this. Prediction: I predict that due to osmosis and diffusion when there is a pure water solution the potato chip will swell
“More than 205,000 new drugs are marketed worldwide every year, most undergo the most archaic and unreliable testing methods still in use: animal studies” (PETA 1). Although animals may seem the like ideal specimens for testing new drugs, the experiments are untrustworthy and can cause unknown side effects. Research on animals is deemed necessary to develop vaccines, treatments, and cures for diseases and to ensure that new products are safe for humans to use. “The development of immunization
Furthermore, she recommends that scientists explore other alternatives, such as, computer simulations and tests on tissue and cells. Although Goodall sheds light on great alternatives and uses great statistics, Goodall’s essay comes off as too preachy and fails to realize that if it were as simple as to use a computer simulation to cure a drug, of course there would be no need
was research published in the BMC Genomics journal by BioMed Central open that had revealed that the response of the laboratory grown human cells can be used to classify chemicals and it can also be used to predict the strength of allergic responses thus providing a good alternative to animal testing. Alternative methods are based on experiments on human cells carried out in vitro (i.e. test tubes), and on computer models (Peta.org par. 2). These techniques are more sophisticated and more precise
Millions of animals are experimented on for makeup and house products. Many die from drugs overdose. Some are stuffed in small cages, badly treated, and have open wounds. Monkeys are bred to use their infants as next victims to experiment on. Experimentation should not be allowed, because sacrificing other animals to keep the human race safe is a poor way to do it. Other options, such as technology and volunteer groups. In 1966, the Animal Welfare Act, known as the AWA, was passed because of animal
