Batteries come in many shapes and sizes. Some are no larger than a pill while others are heavy and huge size‚ but most batteries have one thing in common. They store chemical energy and change it into electrical energy. The cell is the basic unit producing electricity. A battery has 2 or more cells‚ but people often use the world battery when talking about a single cell‚ too‚ like a dry cell. One of the most popular batteries that have a cell is a dime sized battery which we use for watches. Cells

My Most Memorable Academic Experiences: High School and College I am looking forward to describing my most memorable high school and college experiences. I would really love for my teachers to appreciate me for all the hard work I’ve done. For those people that didn’t know about my ambition and what it really meant to sacrifice‚ it meant a lot to my family. I’ve gotten involved in school activities‚ community service‚ and school events and a lot more. I felt that once I graduated from school I

On a daily basis‚ humans are surrounded by noise and unable to avoid its ubiquitous presence. This poses a major problem for teenage garage bands‚ whose parental units do not approve of ear piercing feedback and novice percussionists. Although there is no guaranteed solution to the cacophony‚ sound absorbing material acts as a “noise blanket” to reduce sound to a more tolerable level. The objective of our experiment is to determine if sound absorption by foam and related materials changes with the

The Sugar Act The Sugar Act was not really new legislation by the time British Parliament passed it in 1764‚ but mere an extension of the 1733 Molasses Act. The Molasses Act placed an import tax of 6 pence per gallon of molasses and a 5 shilling tax per hundred pounds of sugar not produced in the British West Indies. Colonists generally ignored the Molasses Act and intimidated tax officials or smuggled the contraband into the colonies. The Molasses

Hypothesis If different age groups are placed in a room for several minutes‚ then the older they are the more time they will think has passed by because time perception is affected by age. Purpose The purpose of this project is to find out if time perception changes with age. Materials ● 3 people ( 1 8 yr. old‚ 1 33 yr. old‚ 1 57 yr.old) ● empty room ● stop watch Procedure Gather a group of subjects‚ ages 8 to 57. Simply tell the people you are conducting an

Background Research I’m doing my science project on which food wrapping will prevent freezer burn the best aluminum foil‚ plastic bags‚ or freezer paper. This experiment seemed interesting to me because a lot of people get freezer burn on their foods. My mother also gets freezer burn on her foods a lot and she always tries different food wrappings but none of them seem to work. This project will benefit people from getting freezer burn on their food‚ and so they will know which wrapping

The Doppler effect Design Variables Research Problem In our experiment‚ we will be testing the validity of the Doppler effect. The Doppler effect states that a change in frequency of a wave will occur for an observer that moves relative to the wave. This is seen in our everyday life‚ for example‚ when the siren of a police car or fire truck passes you‚ you are experiencing the Doppler effect. Key Variables Independent Variable: Original position of moving object (sound maker and

Conclusion My hypothesis was if the temperature increases the Vitamin C content will decrease. The results indicate that my hypothesis was wrong; temperature does not affect the content of Vitamin C left in the orange juice. Future Considerations If I were to conduct this project again I would measure the temperature more accurately‚ conduct more trials‚ keep the juice at a high temperatures for a longer time and use another juice with a lot of Vitamin C content. The purpose of this experiment
