Hi im Ricky I enjoy doing science and math.My favorite colors are red,white, and black.When I grow up I want to be a Marine Engineer.The school I went to before CCMS was JOELLA .C. GOOD ELEMENTARY.

__PROBLEM STATEMAENT__

Which battery lasts the longest? How can power be increased?

Hypothesis:If 4 different types of batteries last the different amount of time I think it would be the biggest one on my project.Power can be increased by freezing it to hold the chemicals. __RESEARCH PAPER__ Power

====Power is the rate of doing work or producing.In other words it is a measure of how quickly work can be done.Power is mostly measured in watts or kilowatts.The formula for energy is __POWER=WORK/TIME .__==== Batteries

A battery can change chemical energy to electricity by putting certain chemicals in contact with each other in a specific way. Electrons, which are small parts of an atoms, will travel from one kind of chemical to another under the right circumstances. When electrons flow, this makes an electrical current that can power something. What a battery does is put the right chemicals in the right relationships, and then puts a wall between them. Only when the two sides of a battery are connected by a wire or another conductor can the electrons flow. How to make a battery and how they work There are two types of battery, the dry cell (like those used in flashlights) and a wet cell (used in automobiles). Inside a dry cell battery is a chemical paste called the electrolyte that can conduct electricity. The electrolyte is made up of billions of billions of positive and negatively charged particles. The battery is housed in a case that is made of zinc and running through the center of the zinc case is a carbon rod. Electrolyte fills the space between the zinc case and the carbon rod. The rod and the case acts as electrodes. Chemical reactions in the electrolyte send positive particles to the carbon electrode and negative particles to the zinc. The electrodes are fitted with contact points which allow the battery to be connected to a circuit. When the electrodes are connected in this way, the charges that have built up on the electrodes are free to move. They flow from one electrode to the other, thus, flowing through the circuit. This flow of charge is what we know as electric current. When the electrolyte cannot produce a charge flow any more the battery is "dead". You can make your own battery at home by using a lemon. Push two pieces of metal into the lemon. These two pieces have to be different kinds of metal (such as a brass thumbtack and a steel paperclip). Make sure that the two metals do not touch one another! Wrap some copper wire around the ends of the metals and connect the other ends of the wire to a flashlight bulb. The light bulb should light up. The acid in the lemon acts as the electrolyte which lets particles move to the electrodes which are the thumbtack and the paperclip. The electricity then flows through the lightbulb until the electrolyte (acid) around the metal pieces is no longer able to react. What are batteries made of?

Battery is certainly the pacemaker of the heart of machines. Most of the machine depends on the voltage and its capacity. It is made of the container, cathode, separator, collector and the electrotype. The container is the housing case of a battery. It is a part where the electro chemical reactions take place. Cathode is the layer where manganese dioxide and carbon mix in order to increase the reaction occurred in container. A separator is a non-woven fibrous fabric that separates electrolytes. Collector is the part of the battery that has a brass pin in the middle of the battery. An electrolyte has potassium hydroxide that gives a solution in water that carries ionic content in the inner part of the battery. = = =12.13.2011-Updated Project=
