Variables Dependant Variable: Time‚ Size of 5cm piece of Potato Independent Variable: Amount of Oxygen released Control Variable: Volume of Hydrogen peroxide‚ size of Potato‚ concentration of Hydrogen Peroxide Hypothesis I predict that the breakdown of Hydrogen Peroxide will be quicker when the surface area is increased. If you cut the same size piece of

Sanfranscisco 49er fans punched and kicked a lone MInnisota Vikings fan. This proves that sports fans can go crazy and be mean to other fans. They are too obsessed with their team and beat up people to show that they like their team. This fact proves that fans can go too far when it comes to their favorite team because they sometimes have riots after games. People also skip school‚ work‚ and even commit suicide over their favorite sports team. After a soccer game in Buenos Aires‚ Argentina‚ fans rioted the

..Year 12 English Essay.. Nowra’s play is set in a ’burnt out theatre’. Discuss the importance of setting and imagery in conveying Nowra’s ideas in Cosi. The burnt out theatre in Nowra’s play ’Cosi’ represents the life inside an asylum‚ a life that the characters know all too well. Life inside an asylum is portrayed as a dark‚ cold and isolated place‚ where the outside world is not often talked about and for others almost doesn’t exist. Most of the characters cannot handle reality but for Nowra

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

LAB 9: DATE: 25TH January‚ 2011. FORM CLASS: L6 3 SUBJECT: Biology 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

Temperature and enzyme activity Aim: To determine the effect of which the temperature of the enzyme has on the rate of the enzyme catalysed reaction. Hypothesis: The rate of reaction of an enzyme catalysed reaction will increase as the temperature of the enzyme approaches the optimum temperature. Surpassing the optimum temperature will result in a drop in enzyme activity. Materials: 6% hydrogen peroxide Liver suspension 10 test tubes 4 beakers Thermometers Measuring cylinders Test

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises
