Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

Chem 21 Fall 2009 Experiment 9 — Recrystallization _____________________________________________________________________________ Pre-lab preparation. (1) Read the supplemental material from Zubrick‚ The Organic Chem Lab Survival Manual. (2) Draw the structure of acetanilide and report relevant physical data. Be sure to cite the source of the data. You should be able to figure out what’s relevant by reading the procedure. (3) Find and report the boiling points of the solvents you will be using

Galileo: Uniformity of Nature and Experimental Physics The Renaissance became one of the factors for the Scientific Revolution‚ bringing on the renewal of ancient times which led to the discovery of "ancient scientific texts (1)." This time period of the Renaissance also known as "the century of genius (1)" brought on a new view of nature bringing about ideas of great minds such as that of Galileo. He could be described as a Renaissance man‚ gifted in many areas as a talented musician‚ an artist

minutes of aerobic exercise. Each suggestive treatment is complete with a reasonable physiological rationale. I have come up with an experiment to test the 3 variables to figure out what treatments if any will work the best. My hypothesis is that all 3 of the suggestive treatments when done before flying on an airplane‚ will reduce the effects of jet lag. Experiment: A commercial airplane traveling from New York City to Los Angles non –stop will be selected at random. All passengers will be randomly

discussion I would like to contrast controlled laboratory experiments and naturalistic observations research methods. In controlled laboratory experiments‚ the researchers conduct their studies in a controlled setting. Conversely‚ studies involving naturalistic observation‚ examine participants in their natural environment. Below I present a contrast of the most essential features of each of these methods of research. Controlled laboratory experiments: • Objective: Seek to compare two or more conditions

Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately

Galileo was an Italian scientist and scholar that made pioneering observations that laid the foundation for modern physics and astronomy. He made a point of saying that you have to do more than just think something is true‚ you have to do it to prove it. With this being one of his principles he made many contradictions of thee only theories at the time‚ Artistole’s mostly. With this he made some enemies but also tried to be true to his Catholic beliefs. His‚ at the time‚ bizarre experiments and methods

Galileo and Newton 2/4/97 Galileo believed the physical world to be bounded. He says that all material things have "this or that shape" and are small or large in relation to other things. He also says that material objects are either in motion or at rest‚ touching or not touching some other body‚ and are either one in number‚ or many. The central properties of the material world are mathematical and strengthened through experimentation. Galileo excludes the properties of tastes‚ odors‚ colors

Galileo Galilei is well known by many‚ but it is hard to pin point the exact reason behind this apparent fame‚ he became famous in terms of early empirical science late on in his life‚ when he wrote his text on the dynamics of rigid bodies Dialogues concerning the Two New Sciences ’ which is a forerunner of Isaac Newton ’s Laws of Motion. However this branch of science was not his passion or what he spent most of his life arguing and theorising about. Galileo was interested in the Copernican theory
