The FDA makes a strong point on why antibiotics should be eliminated from farm animal feed. The FDA uses expert testimony and scientific fact that show why antibiotics have more negative than positive effect. While‚ using antibiotics is cheaper‚ it is more important to be selective about which drugs are given to our animals. There is clear information explaining why antibiotics are harmful to society so it is very important that we use these drugs properly. When bacteria gets into the food supply

100 million animals are used in animal testing every single year to further the understanding of species and the impact of different modern medicines. There are many organizations that are extremely against the use of these animals in medicine‚ saying that it is “cruel and inhumane”. Compare these 100 million to the 56 billion animals slaughtered for food for humans. Those 100 million almost seem like a small amount‚ don’t they? The animals used in scientific testing have contributed to many life-saving

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important. Part II - Relay Assembly Test Room Study (1927-1929)

centuries to the writing of the great philosophers. More than two thousand years ago‚ the Greek philosopher Aristotle wrote extensively about topics like sleep‚ dreams‚ the senses‚ and memory. He also described the traits and dispositions of different animals. Many of Aristotle’s ideas remained influential until the beginnings of modern science in the seventeenth century. At that time‚ Rene Descartes proposed a doctrine called interactive dualism- the idea that mind and body were separate entities that

Summarize the steps of the scientific method. Describe an experiment of your choice‚ which demonstrates the basic considerations that must be taken in the design of a good‚ manipulative experiment. Now that you know some details of how scientists solve problems‚ how might you apply that knowledge to your daily life?

The Hawthorne experiments took place from 1927 to 1933 in the Hawthorne plant of Western Electric. They wanted to test scientific management. The experiments were held by Elton Mayo‚ and a few of his colleagues. The experiments began as a series of productivity studies from a scientific management perspective

experience and interest in the problem‚ I decide to learn more about what makes plants grow. I think about the scientific method which is a logical and rational order of steps by which I can come to the conclusions around me. Scientific method helps to organize thoughts and procedures so that I can be confident in answers I find. I will think through various possibilities using the Scientific Method to come to an answer to my original question. Observation is done first by me so that I know how I want

One advantage of the Scientific method is that it’s replicable. Scientists record their methods and standardise them carefully so as the same procedures can be followed in the future. Investigations are carried out in highly controlled‚ objective laboratory and repeated to gain further reliability. This is an advantage because repeated a study is the most important way to demonstrate the validity of an experiment. If the results of the repeated experiment are the same‚ then this affirms the truth
