two different experimental methods‚ displacement and floatation. The theory is that both methods should have the same density results; the goal is to determine which method is “best”. 1st Method: Displacement This method was first known as Archimedes ’ principle. The principle states that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. (REF: www.infoplease.com) Our group measured density with different amounts of product‚ knowing that intensive

The objective of this Cartesian diver lab is to demonstrate Pascal ’s law and Archimedes ’ principles. Observation is the key to conduct this experimental study of the Cartesian diver. First a 2-liter bottle is filled with water to almost all the way to the top‚ then prepare the diver which is a test tube‚ fill the test tube about

Ralph - One of the main characters in the novel. He has many characteristics such as being very athletic‚ charismatic‚ leading‚ and a smart protagonist of the group of kids. Ralph was elected the leader of the boys at the beginning of the book. While most of the other boys are mainly concerned with having fun and not doing any work‚ Ralph focuses on building huts and thinking of ways to increase their chances of being rescued. Ralph’s influence over the other boys is safe at the beginning of the

Archimedes once said “Give me a lever long enough and a fulcrum on which to place it‚ and I shall move the world..” Archimedes is considered to be one of the greatest ancient mathematicians. Archimedes was born in about 287 BC in Syracuse‚ Sicily. At the time Syracuse was an independent Greek city-state with a 500-year history. Clothing in Ancient Greece primarily consisted of chiton‚ peplos‚ himation and chlamys. Clothes were mainly home made and often served many purpose. Archimedes’ father

called because one thinks of the areas measured expanding so that they account for more and more of the required area. Archimedes made one of the greatest contributions of the Greek. One advancement he made was to show that the area of a segment of a parabola is 4/3 the area of a triangle with the same base and vertex and 2/3 of the area of the circumscribed parallelogram. Archimedes also “invented” the volume and surface area of a sphere‚ the volume and area of a cone‚ the surface area of an ellipse

exhaustion‚ which made it possible to compute the area and volume of regions and solids by breaking them up into an infinite number of recognizable shapes. Archimedes of Syracuse developed this method further‚ while also inventing heuristic methods which resemble modern day concepts somewhat. (See Archimedes’ Quadrature of the Parabola‚ The Method‚ Archimedes on Spheres & Cylinders.) It should not be thought that infinitesimals were put on a rigorous footing during this time‚ however. Only when it was supplemented

Greek legacies are their governmental systems‚ culture and arts‚ and science and technology. Classical Greece was a time where the growth of a community held strong through times of plague‚ wars‚ and numerous breakthroughs. A major legacy left by classical Greece was a government based on direct democracy. With a direct democracy‚ citizens ruled by majority vote. The citizenship was expanded to all free males‚ except foreigners. Those not considered citizens were women‚ slaves‚ and all foreigners

the velocity of the fluid is high‚ its pressure is low‚ and where the velocity is low the pressure is high. Archimedes’ Principle. -It was discovered by Archimedes‚ an ancient Greek mathematician who died in 212 B.C. According to this principle‚ an object immersed in a fluid experiences a buoyant force that is equal in magnitude to the force of gravity on the displaced fluid. Archimedes was assigned by King Hero to find out if his crown was made of pure gold. For a time‚ he was puzzled. One day
