Pyramid. Peter Lemesurier states the following about historians in his book The Great Pyramid Decoded. "The sober truth is‚ of course‚ that no historian has yet advanced an explanation of the Great Pyramid’s construction that is convincing (p. 6)." This was so meticulous‚ right? That there are so many people studied the pyramid but we have not a clear idea about the Great Pyramid. The purpose of this paper is to give the reader some general knowledge about the secret of pyramid of Egypt. How they built

1.03 Scientific Method PART 1 1. The experiment isn’t adequate because there are multiple factors when there can only be one independent variable. 2. If Tyrone and Valerie both fly differently designed paper airplanes then Tyrone’s will fly farther because it has longer wings in comparison to Valerie’s wings. a. independent variable: length of wings b. dependent variables: type of paper‚ wind (if any)‚ shape of plane‚ width of the actual plane

Enzymes are catalytic proteins which speed up the rate of reactions. Every enzyme has a specific function – meaning‚ they can only bind to certain substrates. Because these enzymes are proteins‚ they can be denatured. Enzymes can be denatured by many factors‚ such as pH and temperature. This lab was divided into three parts which examined the effects of pH‚ enzyme concentration and temperature on the rate of which enzymes catalyze. The pH is an index of hydrogen ions. In acidic conditions‚ where

Elena Steffen Mrs. McGreevy ToK period 5 The Structure of Scientific Revolution Define normal science: 1. Normal science describes research as an attempt to force nature into conceptual boxes & is predicated on the assumption that scientists understand the world. 2. Normal science often suppresses fundamental novelties because they are destructive to it’s basic commitments. But because of the "arbitrary element" fundamental novelties cannot be suppressed for very long. How does

1. "The earliest origins of psychology can be traced back several centuries to the writing of the great philosophers. More than two thousand years ago‚ the Greek philosopher Aristotle wrote extensively about topics like sleep‚ dreams‚ the senses‚ and memory. He also described the traits and dispositions of different animals. Many of Aristotle’s ideas remained influential until the beginnings of modern science in the seventeenth century. At that time‚ Rene Descartes proposed a doctrine called interactive

8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules of one substrate. The site of the reaction occurs in an area on

TITLE: Enzymes AIM: To investigate the effect of temperature on the enzyme lipase INTRODUCTION: The phenomenon of catalysis makes possible biochemical reactions necessary for all life processes. Catalysis is defined as the acceleration of a chemical reaction by some substance which itself undergoes no permanent chemical change. The catalysts of biochemical reactions are enzymes and are responsible for bringing about almost all of the chemical reactions in living organisms. Without enzymes‚ these

The scientific method is usually presented in science textbooks to show a simpler way to perform scientific investigations. Although the process of science is never predetermined‚ the scientific method may help create a prediction as to what is going to happen. The scientific representation in a similar way is using the evidence found within the experiments; however‚ this unfortunately does not tell you or show you how the science actually works. The Scientific Method isbroken down into 5 simple
