pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker until the water is gently boiling. Continue to boil until the water has been strongly coloured red by the

Distinctiveness between the right and left hemisphere of the brain Word Count: 995 Abstract The brain assymetry experiment is to investigate on the distinctiveness of the right and left hemisphere in the brain as each hemisphere has certain specializations. The experiment were carried out by initially asking the 25 participant on whether they were left or right handed and they had to choose the chimeric image which appeared younger to them. Laterality quotients were calculated in order to

Abstract: Asch (1951) conformity experiment was conducted to investigate the extent of social pressure from a majority group on an individual. Asch conducted this study because he disagreed with Sherif’s (1935) conformity experiment‚ which had a small light in a dark room that did not move but he wanted to see how social pressure might affect a participant answer. Psychologist had earlier discovered that a small light in a dark room appeared to be moving‚ this was an illusion. Asch disagreed with

“How to Maintain a Saltwater Fish Tank” | | Advanced Composition SUMBO8 – SEC AS Catherine Quick Due: September 7‚ 2008 | A saltwater fish tank is no ordinary fish tank. A saltwater fish tank is a self-supporting ecosystem‚ as long as it is maintained properly. This means that every element in a saltwater fish tank relies on every other element for survival. Stability must be achieved by monitoring and maintaining specific

HYPOTHESIS - 1923 Haldane & Oparin propose hypothesis that life originated as simple molecules followed by cells - conduct simple experiments that show that organic compounds can form cell-like structures 3. EXPERIMENTATION - 1953 Urey and Miller collaborate effectively to design an experiment/model to simulate conditions on early Earth and test

Sulfa Drugs: Preparation of Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution

Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima beans. Background Information: In plant growth‚ calcium effects the metabolic process of other nutrient uptake that is vital for growth of the plant. Calcium also strengthens the cell wall structure (It is an essential part of the cell wall);

Bending Moment EXPERIMENT 2B: SHEAR FORCE AND BENDING MOMENT 1. ABSTRACT Performance-based design approach‚ demands a thorough understanding of axial forces. Bending characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. By this experiment we can verify the limit load for the beam of rectangular cross-section under pure bending. Moments at the specific points are calculated by the method of statics
