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

Aim: This experiment aims to determine what effect an increase in the surrounding temperature has on the plasma membrane of a typical plant cell structure. Hypothesis: An increase in temperature will damage and denature the plasma membrane and cause the cytoplasm and other substances contained within the membrane to leak out. Introduction: The purpose of a cell membrane is to control the transport of substances moving into and out of a cell. The membrane is an extremely thin layer (8 to 10 manometers

The effect of temperature on the cell membranes of beetroot cells and amount of pigment released. Apparatus • Corer size 4 • White tile • A Beetroot • Automatic Water Bath • Segregated knife • A thermometer • Stopwatch Method: • First take the white tile and the corer. Then collect a cylinder of beetroot by pushing the corer into the beetroot and withdrawing it. The cylinder remains inside the corer- so push it out with the end of a pencil. • Collect 3 cylinders

Goldfish Respiration Abstract The purpose of this experiment is to tests the effects of temperature on the respiration (breathing) rate of goldfish. In order to determine the goldfish respiration change adding small amounts of crushed ice to the water‚ than behavior will be noted. Then‚ the goldfish will experience the same experiment four more times and be noted again. This experiment will be conducted with four students‚ one goldfish‚ a 250 mL and a 150 mL beaker‚ thermometer‚ crushed ice‚

of metabolism of a dried yeast culture with differing carbohydrate sources? In the current practical that was undertaken the growth rate of yeast (S. cerevisiae) with differing carbohydrates sources : Glucose (C6H12O6)‚ Fructose (C6H12O6)‚ Lactose (C12H22O11)‚ Xylitol “(CHOH)3(CH2OH)2” and Water (H2O) as a Control were observed. “ Yeast are single-celled fungi which consist of more than one thousand different species which have been identified. The most commonly used yeast is Saccharomyces Cerevisiae

enzyme produced in the inner lining of the abomasum. Renin will solidify milk and makes it curdle. Curdling of milk is essential for the proper digestion of milk proteins in the stomach. (buzzle) Aim: To analyze the effect of temperature on Renin and to find the best temperature for enzyme activity Hypothesis: Renin works the best in which the rate of reaction is at the highest or optimum‚ in 40˚C Materials: • Bunsen burner • Wire gauze • Thermometer • Dropper • Mortar • Pestle •

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must not exceed

glucose to a solution of KMnO4 and H2SO4‚ the solution will turn colourless and it will take a specific time for the reaction to complete. By increasing the temperature‚ the time it takes (the rate) for the solution to completely change to colourless will be increased. Thus it can be said‚ that it is being hypothesized that an increase in temperature will cause an equal increase in the rate of the reaction. Method:1). Using a measuring cylinder‚ place 50 cm3 of sulphuric acid into a 250 cm3 beaker‚ add

the Effects of Mass and Type Of Sugar on Yeast Fermentation Lab Purpose: To measure and analyze the effects of various types and masses of sugar in an ethanol fermentation reaction with yeast. Introduction: Ethanol fermentation is a system in which hydrogen ions from NADH + H + are broken down in order to release the trapped energy and regenerate NAD+. In the absence of a mitochondria or oxygen ethanol is formed‚ which is typically found in bacteria and some yeast. Yeast fermentation
