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

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

produce than in most other markets. The West Indies‚ being a major trading partner of Britain at the time‚ requested Parliament help prevent the American colonies from buying cheaper molasses and sugar. Northern colonists were more afraid of the methods that Great Britain took to enforce the Sugar Act than the actual cost of the tax itself. The British Navy began patrolling the shipping lanes to the colonies and customs agents became more aggressive in collecting import duties. The Southern colonies

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

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

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

We all know the pain of having to do a science fair project. Your teacher assigns it to you six weeks before it’s due‚ but you wait until the last second because who doesn’t love the stress of staying up really late finishing a project. Doing a science fair project is a long‚ exhausting task that of course is always fun. The first thing you must do is get tissues ready because we all know you are doing this the night before it’s due. Then you have to find a topic‚ so of course you go on your phone

About Cupcakes The cupcake evolved in the United States in the 19th century‚ and it was revolutionary because of the amount of time it saved in the kitchen. There was a shift from weighing out ingredients when baking to measuring out ingredients. According to the Food Timeline Web‚ food historians have yet to pinpoint exactly where the name of the cupcake originated. There are two theories: one‚ the cakes were original cooked in cups and two; the ingredients used to make the cupcakes were measured
