Electrical safety Essay

1. Perform an Internet search about home electrical arctic. What are the advantages of using a circuit with a GFI detector when completing a physical science lab that substance abuses hot water? (2 points) The advantages of using a circuit with a GFI detector when completing a physics lab that uses hot water is that it prevents you from getting shocked. If part of your body were to be touching water or the ground the GFI detector would help prevent burning at the stake should the equipment have a short in it.2. Conduct an Internet search for information on home fire safety. Discuss several common, careless practices that whitethorn lead to a home fire while conducting a home physics taste. (2 points)There are a number of dangers that may lead to a fire when doing a physics experiment if one is being careless. Some common examples are as follows handling flammable liquids carelessly, a Bunsen burner or other gas emitting equipment that has cracks or leaks, not heating flammable c hemicals in a water bath and a student who is not paying forethought and leaves an open flame unattended. All these examples may cause suicidal situations and foundation all be easily prevented should the experiment be done with caution.3. Discuss cardinal things you apprise do to protect yourself from contamination/ imperfection in the laboratory. (3 points) Aside from merely being careful there are a number of slipway you can protect yourself from contamination and or injury in the laboratory. The first would be to not have an open beverage and or food in the laboratory as this could easily become contaminated. Pens, pencils and all other materials should be kept out of your mouth. Avoid having long hair dangling in the conk out space as well as loose clothing, jewelry and wearing open toed shoes as these can all cause dodgy situations for injury. Always dispose of glass material in the appropriate labeled container, know all forwardices for emergency equipment such as a fire extinguisher and first aid kit and always know howto operate the equipment you are using before doing so.4. Discuss the treads of the scientific method. (5 points)The scientific method is a series of steps we use in order to perform an experiment. The first of these steps is to observe, at this stage you are creating an interest or wonder in something. The second step is to hypothesize or form a question of what you think the outcome of the experiment ordain be with support from your observations. Experimenting is the third step which includes two stems both identical except for the variable you are trying to test called the independent variable. These groups are known as the control (remains unchanged) and the experimental group (the one with a changed variable). The conclusion is the final step and at this stage the hypothesis is either accepted or rejected.5. Compare and contrast a scientific law or principle with a scientific theory. (2 points)A scientific law or princ iple is contrasting than a scientific theory in a few crucial ways. A scientific law is something that has been proven correct by numerous different people a number of different times all concluding that it is correct. A scientific theory is a guess or belief that something is true and may or may not be correct, some may support it and others may not but it has not been proven overwhelmingly true.6. Imagine you are a tour go across for a major science laboratory. Write a short script for a tour that summarizes what scientists should (or shouldnt) wear in the lab, what safety precautions they should take, their cleanliness rules, and what they should do in look of an accident. Your script should contain at least ten of the rules or other important points from the lesson. (5 points)Good morning prospective scientists my name is Heather Klein and I will be your tour guide this wonderful day. We are going to begin our tour with some important safety guides in order for everyone to be the best, safest scientists they can be There will be no eating or drinking out of an open container in the lab We are all to be wearing close toed shoes, with no baggy clothing or jewelry and hair is to be tied back as all of these can cause dangerous situations. It is important that no onewear contact lenses and we all wear glasses or goggles when working with dangerous chemicals. ahead beginning labs we are to disinfect our counter tops with a 10% bleach solution.Upon beginning the lab each of our scientists makes sure there is only indispensable materials at the work place. They are also very aware of how to use the equipment before they begin and make a mental note of all the exits and safety material in case of an accident. When its time to dispose of chemicals our scientists always do so in the appropriate containers especially glass. Should there be an injury in the lab, it is to be reported to the instructor or medical professional immediately. We always conclude our exp eriments with thoroughly cleaning the area and our hands as dangerous chemicals may go unnoticed otherwise. We hope everyone enjoys the tour and respects the important safety rules.7. How can you use the information regarding laboratory safety, or how can you get into this knowledge to your everyday life as a non-scientist? (2 points)The knowledge of laboratory safety may be used in everyday life in a number of ways. In the laboratory it is important to pay attention to what you are doing, use something and then put it back in the correct location and not use equipment you are unfamiliar with. These same ideals can be incorporated into everyday life as it is also important to pay attention, not leave dangerous items unattended and to not use things without first permission or knowledge on how to use them. Even non-scientists should abide by these rules in everyday life as it can prevent accidents or dangerous situations. 8. In the morning, you get in your car on the way to work, tu rn the key, and zip happens Use the steps of the scientific method to explain how you would solve this problem. (4 points)In order to solve the problem of my car not stick outing I would use the steps in the scientific method to first observe if there are any obvious signs as to why the car isnt starting. I would then form a hypothesis as to why I believe the car isnt starting such as, The car wont start due to the fact the battery is dead from a light being left on. In order to test my experiment I would twitch my car up to another car via some jumper cables and then again try and start it again. If it worked my hypothesis is correct and I am off to work for another day. If the car does not start than I amincorrect and I must again observe, hypothesize, test my hypothesis in experiment and find my conclusion.
