Observe what battery will off first. We can just prove it if they are wrong or not if we perform this experiment further. Batteries have been made with many different chemical compounds.
So we can conclude that Rayovac is more practical to use than the other branded batteries. If you have a budget you can also use a stopwatch so that you can record the right time you have started and the time where the battery died.
Place one end of the black wire under the other screw, make a loop and then tighten the screw and after that pass the open end of the red wire through the arm of the red alligator clip and secure it under the screw next pass the open end of the black wire through the arm of the black alligator clip and secure it under the screw then screw the light bulb on the miniature base next connect the red alligator clip to the iron electrode and secure it on one side of the plastic container or the cup and connect the black alligator clip to the magnesium electrode and secure it on the opposite side of the container.
Batteries are used for our portable electronic equipments such as watches, cameras, calculators, radios, cellular phones, flashlights, computers, remote controls and many more. Instead using of batteries that we can buy in stores even go to the stores or malls to buy batteries because the materials that needed in our project is easily to find.
Conclusions and Recommendation We conclude that the electricity you produce can be high enough to light up a light bulb. Instead of using batteries that is not practical to use we will know what battery is more practical to us.
Alkaline solutions can irritate eyes and cause dryness of skin. The community uses the battery in electronic devices such as camera, calculators, watches and etc. We will also try to determine in this project if the power of the battery affect the cost of it.
We see in this table that our first trial is not effective while our second and third trial become effective. In making this project we will learn about electricity and technical differences of the batteries. Avoid contact with the used saltwater solution.
The battery that long lasted is the rayovac its total time is 26hrs and 15mins. Project Manager and Stakeholders Project leader is no other than Earnesto the stakeholders By adding a small amount of hydrogen peroxide you can get lighter and the light will last longer.
You can extend the power by adding oxygen. First put all your batteries in you homemade circuit.
We will determine if the cost of the battery has an effect to its power. Some of our grandma or grandpa is putting the batteries inside the refrigerator. We will compare other samples of batteries that are available in the market.
Batteries are used for our portable electronic equipments such as watches, cameras, calculators, radios, cellular phones, flashlights, computers, remote controls and many more.
In this project we need to determine what brand of battery that last longer than any batteries that is suggested by others. It can help us to find out what battery will be more practical to use. The difference is that the researcher is not really burning anything; instead the researcher producing a condition of oxidation which by itself is the same as slow burning.
It is also safer than batteries that use many harmful chemicals.
Making a battery is always an exciting science project. The reasons why they are doing it because they want to save the power of the battery. This is the very important materials because those batteries are batteries that we will test, what batteries will stay for a longer time.
During this experiment we will learn about electricity and technical differences among different batteries. Record it in your record notebook.Search the world's information, including webpages, images, videos and more.
