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

oC)Hypothesis:By adding 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

Hypothesis The optimum temperatures of Alcalase and Savinase will be different. Above and below their optimum temperatures activity will decrease. Biological explanation This investigation is designed to look at the effect of temperature on the activity of the proteases Alcalase and Savinase. By the end of it I hope to know the optimum temperature of both proteases. The substrate I am going to use during the experiments is the protein gelatin‚ which is a translucent‚ colourless‚ brittle solid

Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals

Effec | Effect of caffeine on plant growth | Description This science fair project was performed to find out the effect on plant growth of adding caffeine to the soil. The experiment was done by using mung bean plants and watering them daily with water‚ water mixed with caffeine and with a coffee mixture. Hypothesis The mung beans watered using the coffee mixture will grow the fastest. Overview Caffeine and plant growth The effect of adding caffeine to the soil and its effect on plant

Investigate the effect of temperature on amylase activity Introduction Amylase is an enzyme that catalyses the breakdown of starch into sugars. Amylases are found in almost all plants‚ animals and microorganisms. Large amounts of amylase occur in germinating cereals‚ and in the pancreas and saliva of higher animals. Aim The aim of this experiment is to find out the rate of reaction between amylase and starch in a range of different reaction temperatures. Hypothesis As the reaction

INVESTIGATING THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific

Effect of Temperature on Content of Vitamin C Introduction A daily intake of Vitamin C is essential for humans. Without it‚ the disease scurvy develops as sailors‚ explorers and people during the long winters in the Northern hemisphere found before the time of Captain Cook. The British Navy started giving sailors lime juice to prevent scurvy on long voyages in 1795. Vitamin C is found in high levels in foods such as oranges‚ limes‚ lemons‚ blackcurrants‚ parsley and capsicums. Vitamin C is water
