Simple Experiments on the Enzyme Catalase Aim: The aim of this practical is to use three different techniques to investigate the effect of different concentrations of the enzyme catalase on the rate of breakdown of hydrogen peroxide. Background information Catalase is an enzyme which is found in all living organisms. This enzyme catalases the decomposition of hydrogen peroxide into water and oxygen. Cells continually produce a poisonous by-product of metabolising‚ called hydrogen peroxide. This

Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled

Goal of Interaction: After participating in the 9am unit meeting the client stayed in the break area coloring. I introduced myself to her and asked her if I could sit down next to her. A few more clients and students joined us‚ a few minutes later we participate in the therapy unit meeting. When the meeting concluded‚ the whole group of people interact and exchange a few words so I asked the client if it was okay with her to talk on a one to one meeting and ask her a few questions to which she agreed

Dictogloss represents a major shift from traditional dictation. When implemented conscientiously‚ dictogloss embodies sound principles of language teaching which include: learner autonomy‚ cooperation among learners‚ curricular integration‚ focus on meaning‚ diversity‚ thinking skills‚ alternative assessment‚ and teachers as colearners. These principles flow from an overall paradigm shift that has occurred in second language education (Jacobs & Farrell‚ 2001). While there are many variations on

Symbolic Interaction Approach From the sun there grew a beautiful flower that had the magic ability to heal people. An evil woman found the flower and hid it from the rest of the world for her own selfish desires. Every time she would sing a certain song to the flower it would make her young again. Over and over again for hundreds of years she would reverse time to make herself young and beautiful. In a kingdom not far away from the evil woman and her magical plant‚ there was a king and queen

Biology Fermentation Practical "A comparison of the respiration of yeast in different sugar substrates" Aim: The aim was to compare the respiration of yeast in different substrates of sugars‚ i.e. between a monosaccharide (glucose) and a disaccharide (maltose) Theory: There are three types of Carbohydrates‚ monosaccharides‚ disaccharides‚ and polysaccharides. The two‚ which I will be looking at‚ are‚ monosaccharide (glucose) and the disaccharide (maltose) Classification and major properties of

Topic: Divorce There are three significant causes of increasing the divorce. The first main cause of getting divorce is because women have changed their parts. As we know‚ nowadays everybody has equal rights to do anything‚ unlike in the past only men could do whatever he wants. Before‚ men have to go out and earn money in order to afford the expense of family‚ whereas women only do housework and look after the children. Since women have no job‚ she has no money to support the family besides
