...Science: From Methods to Mutation Professor Atkins Submitted by Paula Ahl October 1, 2012 PART I: SCIENTIFIC METHOD Each and every day, we are faced with having to make split-second decisions, and the need to solve random problems that we encounter. To reach those decisions and work those problems out you are subconsciously using the scientific method. Apply the five steps of the Scientific Method to two situations that could occur in your everyday life. Use the scientific method in the first scenario provided below to solve the problem at hand. Please come up with a second detailed scenario on your own and follow the same steps in the scientific method to find a resolution. Scenario 1: You arrive home late at night. You walk up to the front door, unlock it, and reach in to turn on the light switch located just inside the front door. The light does not come on! Now what? 1. Name the problem or question you are trying to solve. One evening I came home late, my husband and children were out for the night, I unlocked the front door, reach in to turn the light on and it doesn’t come on. I go back to my car for the flashlight. I need to identify where the problem is generated from. Why doesn’t the light turn on when the switch is switched on? 2. What is your background research? Check the neighborhood to see if electricity is out. Check to see if breaker has flipped. Check to see if the light bulb has burnt out. 3. Construct a hypothesis based on the facts...

...Fregrene The Evolution of the Battery and Electric Vehicle After reading various articles on battery chemistry and how it applies to electric vehicles’ I have come to a conclusion. Although electric vehicles may seem like a great idea for many people, because they can eliminate a great amount of emission pollutants in the atmosphere, they arrive with many unresolved issues. Issues which may be expensive as well as incovineient to solve. The first article I read was “Chemstry’s Electric Oppurtunity” by Alex Scott. In his article, he spoke of the automobile firm Tesla and their new Model S vehicle. The Tesla Model S is a vehicle capable of driving up to 300 miles before needing to recharge, compared to the majority of other electric cars who can only reach 100 miles. The CEO of Tesla Motors, Elon R. Musk claims that “anything a gasoline based vehicle can do, the Model S can do” (Scott, pg 1). Which may prove to be true since the car goes from ‘0-60 in only 4.2’ (Scott, pg 1). Many people wonder how the Model S is capable of outperforming other electric vehicles. It is due to the car’s large 670kg battery. This battery provides an energy density of 240 Wh/Kg. ‘This is much denser than the nickel based batteries of other firms such as Toyota, Nissan, and GM’ (Scott, pg 2). It’s great that Tesla is able to raise the bar in the electric vehicle field and provide a more efficient vehicle for consumers to enjoy, however there is a large inhibitor. Batteries are just not as efficient as...

...laptops are better to have than desktops. Although they are very convenient and portable, desktop computers are faster, easier to work with, and have more features. What is best for one person may not be best for another person. They both have their advantages and disadvantages, but for each we have to consider whether the good outweigh the bad. We have to take into consideration price, size, speed, and capacity, battery life, and stability. Laptops are usually more expensive than desktops because that are a great deal smaller and still have many of the same components as a desktop. Because of the way they are designed, components have to fit into a small compact space, conserve power, and produce less heat. Repairs and maintenance will cost more because they usually require professional work in order to be fixed properly. The parts are also smaller for laptops, making them more expensive. The most obvious difference between laptops and desktops is size. This is also the main reason a person may choose to get a laptop. They are much smaller and lighter, which makes them easier to travel with. You can go anywhere, anytime, and still have access to a computer. You can receive wi-fi, so the internet connection should not be a problem. You are not tied to one particular desk, and you have the freedom to move around with them. They are great for class and work presentations. When you get a desktop home and place it that is probably where it will stay because it has to be plugged into...

Alternative Title: The risk of buying a 18650 battery charger not certified by the Underwriter’s Laboratories! Exploding cell phones and batteries acting like mini rockets, spewing smoke and fire stand testament to the fact that lithium-ion batteries can be very dangerous if the charger used with them does not work as it should. In fact, the numerous horror stories of charred houses and serious burn injuries are enough to prove that a UL certification should be a crucial factor to consider when buying a 18650 battery charger. Do not use battery chargers that have not...

...Homemade Batteries Homemade batteries are a popular subject with my readers. Making electricity from things you find around the house is a fun project. There are lots of easy ways to make homemade batteries. Basically, any two different kinds of metal can be placed in a conducting solution and you get a battery. Familiar homemade batteries include sticking copper and zinc strips into a lemon or a potato to make a battery. One quick battery is made from a soda can, the soda from the can, and some copper. Click on image for a larger picture The photo above shows a battery made by placing a strip of copper and a strip of aluminum into a glass of Coca-Cola (I used the sugar-free cherry flavored variety because that's what I found in the refrigerator). You can make the aluminum strip by cutting open the can. You will need some sandpaper to sand off the paint and plastic coating from the aluminum before using it. Or you can get strips of aluminum already free of coatings from a hardware store, or from our catalog. You can get copper flashing from a hardware store and cut out a strip of it, or you can use a bunch of copper wire (the more surface area exposed to the liquid, the more electrical current is produced). Or, as before, you can get pre-cut strips from our catalog. The aluminum-copper-coke battery will produce about three quarters of a volt. Click on image for a larger picture Using a zinc strip instead of the aluminum produces a little over a volt in the copper-zinc-coke...

...Duracell Duracell is one of the most recognized, on a global level, battery producing companies. Duracell is also a member of the Gillette Company, and the global market leader, covering over 50% of the U.S. market share. Duracell, however, has often had to rethink its marketing and pricing strategies to stay competitive, especially against low cost competitors which started appearing on the market in the late 1990s. Technology has advanced dramatically lately, and the devices usually powered by Duracell batteries have developed their own rechargeable batteries, or have shrunk in size, become incredibly small and calling for a complete redesign of the concept of battery. Duracell has launched new redesigned lines of batteries often during the last decade, but never revolutionized the concept of battery, for obvious technological reasons. It is important to keep in mind that Duracell, as part of Gillette, follows a centralized marketing and research and development approach which is guided by the Gillette Corp. In order to get an idea of the current state of Duracell, I will offer a quick recap: Duracell currently covers over 50% of the North American (Including U.S.) market, its sales have been over 2 Billion dollars per year since the early 2000s and currently retains the best relationships in terms of pricing and spread with its distributor and retailer channels compared to any other consumer battery manufacturer worldwide. Currently, Duracell’s efforts have been focused...
