The Lava Pit One time in Hawaii‚ in 1888‚ there was a small village just next to a little beach. Not far from the village‚ there was a huge “lava pit.” Scientists believed that it was just a volcano that had formed underground and only the opening at the top could be seen from the surface. The lava pit had always been filled with lava‚ and people wondered if it would ever erupt. For many years‚ tourists have visited Hawaii and come to see and take pictures of the lava pit. Unfortunately‚ many people

of the American Pit Bull Terrier* comes up‚ the issue of nature vs. nurture is always a hot topic. Over the years‚ varying schools of thought have evolved with respect to the dog fighting heritage of the bull breed and their inclination toward aggressive behavior. Before we go any further‚ let ’s get one thing out of the way right off the bat. Throughout history‚ many breeds of dogs were used in dogfighting. The Romans fought dogs in their great arenas long before the American Pit Bull Terrier ever

The Twentieth Century Fox Studio Classics DVD release of The Snake Pit from 1948 features a commentary by Aubrey Solomon‚ who has written two books about the films and history of that film studio. The movie was based on the bestselling novel of the same name by Mary Jane Ward‚ telling the story of Virginia Cunningham played by Olivia de Havilland‚ who was a major Hollywood star at the time. We see her at the start of the movie in an insane asylum‚ bewildered by her surroundings‚ and utterly confused

Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In

Symbolism Symbolism is the use of symbols to signify ideas and qualities by giving them symbolic meanings that are different from their literal sense. Symbolism can take different forms. Generally‚ it is an object representing another to give it an entirely different meaning much deeper and more significant. Sometimes‚ however‚ an action‚ an event or a word spoken by someone may have a symbolic value. For instance‚ “smile” is a symbol of friendship. Similarly‚ the action of someone smiling at you

I will be demonstrating the law in which connects the period of the pendulum‚ expressed as T‚ to the length of the string‚ expressed a L. The system the lab will be based on will include a pendulum with a weight of W suspended at a fixed point by the string with a variable length of L and an angle theta to be measured using a protractor. The variable T will be measured as the period of time needed for the weight of the pendulum to swing back and forth once. For part 1 of the lab‚ we will be measure

The reason for the failure of the current correctional system and all correctional systems in the history of American prisons is an imbalance in the goals of criminal sentencing. These goals

Introduction: Aim: To find the relationship between the length of a simple pendulum and the period of oscillation. Research question: How does the string length of the pendulum affect the period of oscillation? Prediction: The longer the string‚ the longer it will take to make one complete oscillation. Variables: Independent variable: Length (L). Dependent variable: Period of oscillation (T). Controlled variable: Mass of the plasticine. Tools & Materials: Stopwatch. Ruler. String. Plasticine
