Investigatory Project

Benjamin Franklin and the Lightning Rod- In 1750 Benjamin Franklin set out to prove that lightning was electricity. Franklin constructed an iron rod with a sharpened end and grew impatient because it wasn’t conducting. He theorized that his sharp iron lightning rod did not conduct any electricity so many people used them for protection from

Ben Franklin was a very curious and inventive thinker. He kept thinking about different ways to experiment with electricity so he came up with an experiment with only a few materials (wire,mobile kite, handkerchief,and two sticks).(”Benjamin Franklin and Electricity”) Franklin

The range of normal resting systolic BP for the subjects in this experiment is 115-125 mmHg. Did systolic BP increase, decrease, or not change with exercise?

Otherwise their static. No one believed Maxwell, and Hertz set out to prove Maxwell right. Hertz used two rods to serve as a receivers. When the applied a spark to one of the rods, he could get it to jump to the other rod. Hertz discovered how to make the electric and magnetic fields separate themselves and travel freely. ("The origins of radio, n.d." )

The kite experiment influenced by the works of other great scientists such as Isaac Newton and Joseph Addison, Franklin wrote his most important scientific work: Experiments and Observations on Electricity. The kite experiment of Benjamin Franklin was to tie a kite with a metal skeleton thread, with its lower end attached to a key. Taking advantage of a thunderstorm, he noted that, trace the comet, electricity is led from the kite to the key, charging outlet. From this, Franklin showed that the clouds were electrically charged and lightning we see are these electrical discharges. Among the inventions of Benjamin Franklin is the lightning conductor, produced from the just mentioned discovery. The lightning rod installed quickly across the country and was a commercial success

Science is such a unique and highly captivating subject that so many young students find interesting and yet it is also a subject that the vast majority of students get discouraged by as well as lose interest in as they get older. There are so many different areas of science it is easy to be overwhelmed and get discouraged if you easily do not understand something. For this reason, I had decided I need to research a Citizens Science Project that I could bring not only bring into my future classroom but share with my students and their families as well.

The researcher would like to thank the following people who help and give guidance to make this project

He began his work on what was thought of as the electrical phenomenon in 1746, and insisted that electricity was no different to "vitreous" electricity. Franklin was the first to label them as positive and negative, as well as discovering the principal of conservation of charge. Franklin published a proposal for an experiment in 1750, where he intended to prove that lightning was electricity by flying a kite in a storm. Many scientists tested this, some electrocuted in the process, and confirmed Franklin's

Most of the time the price of the preferred dividends is higher than the common stock because there is more risk for investors but there is also more payoff if it does well.

In 1747 Franklin began his electrical experiments with a simple object that he had received from Peter Collinson in England. He advanced a tenable theory of the Leyden jar, supported the hypothesis that lightning is an electrical phenomenon, and proposed an effective method of demonstrating this fact. His plan was published in London and

In 1752 Franklin devised another experiment to test if lighting has an electrical charge. He flied a kite carrying a pointed wire in a thunderstorm and attempted to test his theory that atmospheric lightning is an electrical phenomenon similar to the spark produced by an electrical frictional machine (Bruno 406). To

The overall purpose of the lab is to have the students practice designing an experiment, gathering data, and then analyzing that data to form a conclusion using the scientific method. It also served to understand key terms such as hypothesis, dependent variable, and independent variable. The specific objective of this lab is to determine whether certain human body parts experience allometric or isometric growth. Allometric growth defines when certain parts of an organism grow at unequal rates in comparison to its whole, while isometric growth is when all parts of an organism grow at the same rate in comparison to the entire organism. The specific purpose of the lab is to determine whether or not specific human body parts experience allometric or isometric growth by comparing the ratios of height to two specific body parts, in the students’ case the right hand length and head circumference, in students and newborns. The students formulated the tentative answer that if a team of four compared their height to right hand length ratio, as well as, their height to head circumference ratio, to those of a newborn’s, then the students will discover that the right hand and head experience allometric growth in humans.

Originally electricity and magnetism were thought of as two separate forces. This view changed, however, with the publication of James Clerk Maxwell's 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments:
