2013 ECE 204 ECE Science: More Than Dead Leaves and a Magnifying Glass! Author: T .Wright This is a blog emphasis on how important it is that as teachers of young children‚ we should take the opportunity to provide our students with the chance to make discoveries‚ develop theories‚ and test their hypotheses. We must give them a safe environment with adequate materials to help them extend their understanding of the world around us. I like what the article is about. Science is not just a set

Science makes discoveries ... and the list would be interminable. The underlying question is: what use do we make of these discoveries? In some cases‚ it’s a political issue - look at the huge number of scientists concerned with developing the atomic bomb who begged Truman not to actually use it to destroy cities. (Why were they developing the bomb in the first place? because they thought that Hitler had much of the necessary knowledge and wouldn’t have been so conscientious about how he used it)

Science is a method of understanding how things work. It is important because we need science in order for things to work and to develop new technology that is used in every day life. It is personally important to me because I really want to become a vet when I get older and I would need to do really well in science. Even though science isn’t exactly my best subject‚ I am willing to put in the hard work and determination so I may eventually get better and learn what I need to know. Science

creator of the worlds most dangerous weapon‚ The Value of Science can be interpreted on an entirely different level as Feynman goes back and forth on the concepts of good vs. evil as a way to reflect his moral conscience. Richard Feynmans’ morality can be seen through his passages about good and evil in the world of science and the world outside of science. During Feynmans’ opening point he states that when good things are created because of science it is because “moral choice” (Feynman 64) led them to

Some people believe that science and technology increase have positive effects in our life. In my view‚ it is difficult to say whether developments in science‚ technology and other areas of society in the last 100 years make it better to be alive now. Nowadays we can get lots of benefits from science and technology‚ for example‚ medicine‚ transport and communications. If someone gets a disease‚ there is enough medical knowledge and good medicine to treat them or make them live longer. Secondly
