is a dime sized battery which we use for watches. Cells force electrons to flow along conductors.(DK Science 150). "The electrical force of a cell or battery is called its electromotive force (emf). This force‚ which makes electrons flow around a circuit‚ is measured in units called volts (v). Each king of cell has a particular emf. A dry cell‚ for example‚ has an emf of 1.5volts." (DK science 150) The other way to measure a battery is by how much current it can provide. Current is used to measure

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

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 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 was to determine if raising

Doppler effect is valid. If the sound travels from point A to point C and passes the listener at point B‚ then the wave frequency will change by becoming higher and then lowering after passing point B. Design Materials Our materials for this project include: * Sound recorder on IPod Touch * Isolated parking lot with limited outside noise interference * Piano App on Laptop to produce constant sound * Speakers * Meter stick * Car Method 1.

Abstract I wanted to find out: If you could smell instead of tasting actual food. I read about: People smelling food and they could actually taste it. I (did): I had people smell food and they could actually taste the food like they were eating it. I found out: You can smell instead of tasting the actual food. Next time I will: Try to find if you can taste instead of smelling switch it around try new things. Title Topic: Investigate the influence of smell on taste. What is your control

RESEARCH: Hydroponics is a subset of hydroculture and is a way of growing plants using mineral nutrient solutions‚ using just water. Researchers discovered in the 18th century that plants absorb mineral nutrients as inorganic ions in water. Normally soil is thought to be required for plant growth‚ but in actuality‚ soil is not needed at all. When the mineral nutrients in the soil dissolve in water‚ plant roots have the ability to absorb them. When the required mineral nutrients are introduced

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

As soon as she got I thought she was going to give us an easy assignment to complete in a day or two‚ but this time that was not the case she ended up giving us the longest homework of the year and it was our science fair project. The assignment took us about a month to complete because she took it in steps since it was the first time that anyone was going to do it. The first step is the same as anything you do in your everyday in life and it is what
