Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is

Aim: To determine the rate law of chemical reactions Introduction: The aqueous solution of potassium peroxydisulphate can oxidize potassium iodide as follow: Equation: K S 0 (aq) + 2KI (aq)->2K S0 (aq)+I (aq) 2 2 8 2 4 2 KI(aq) +I (aq) -> KI (aq) 2 3 _________________________________________________ K S 0 (aq) +3KI(aq) -> 2K S0 (aq)+ KI (aq) 2 2 8 2 4 2 The rate law of this reaction can be represented as follow: Rate=k[S208 2-]^a [I-]^b When the concentration of peroxydisulphate ions

All children are unique and develop at their own rate but they tend to follow a similar pattern. There are a number of areas of development like‚ Physical‚ communication‚ Social‚ emotional‚ behavioural‚ Intellectual and moral development. Development is very rapid in the early years of a child’s life and tends to slow down the older they get. Moral development is usually adapted from the setting a child lives and would usually deem something wrong and right‚ based on what their parents believe is

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They

My topic for the science fair project is "The effect of temperature in energy loss in a basketball". Some of my subtopics for my project include the pressure air and height in a basketball‚ the material a basketball is made out of and the size of the ball. Different sports require different size balls to correspond with the correct bounce it needs to be used during the sport. Thats why you would not be able to use a tennis ball to play basketball because it is too bouncy and a soccer

Effects of SO2 On Fermentation Rates Purpose SO2 is the primary inhibitor for natural microbiological growth in wine. It prevents the browning of juice by inhibiting phenol oxidase activity and kills the natural yeast cells for the utilization of fermentation-controlled commercial Saccharomyce strands (Boulton et al. 1996). SO2 is pH and temperature dependent and can exist as several forms. The bisulfate form (HSO3-) can complex with soluble solids such as anthocyanins and acetaldehydes to become
