of informing an audience about a particular person‚ place or issue within society. This film style is very popular with filmmakers for when they want to tell a person or place’s story like in The OASIS and the work of Captain Paul Moulds; a volunteer for The Salvation Army and manager of Sydney’s OASIS refuge. The Australian film is a full length documentary filmed over two years that provides a realistic observation of Paul’s efforts and the challenging lives of the homeless youth. They achieve

EXPERIMENT 3: IDENTIFICATION OF FOOD CONSTITUENTS IN MILK. INTRODUCTION: In this experiment two milk samples are given and its compositions are tested using different methods such as using benedict solution to test the presence of reducing sugar‚ using copper II sulphate to test the presence of protein‚ using K3( to test the presence of fat. However in this experiment‚ not only are the milk tested for its composition‚ the amount of the particular substance such as reducing sugar‚ protein and

Figure 1. Average Mass Specific Surface Area for Three Fish. Error bars represent standard deviation from the mean. The graph represents the mass specific gill surface area for a sample size of 6 gill arches for each of the 4 lab sections (n=24). For Mackerel‚ the mass specific gill surface area was 13.62 cm2/kg. For Whiting‚ this value was 9.34 cm2/kg. Lastly‚ for flounder this value was 2.93 cm2/kg. Results: The three different species of fish‚ Mackerel‚ Whiting‚ and Flounder‚ have distinct

affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with the acid. This is because the acid only comes in contact with the particles on the surface of the donut. But‚ if you crush

indicator that would change from green to pink when exposed to HCl. To prepare the agar blocks‚ I used knife and ruler to acquire 5 agar blocks with equal dimensions of 3.0cm by 1.0cm by 0.5cm. Then I prepared 5 different concentrations of HCl with equal volume of 5cm^3 in test tubes‚ which were 0.0M. 0.2M‚ 0.4M‚ 0.6M‚ 0.8M and finally 1.0M of HCl. Then‚ I placed the agar blocks into respective test tubes‚ measuring the time taken for the agar blocks to turn from green to completely pink. This was repeated

After performing this experiment‚ it was found that the surface the chocolate was placed on could make a major difference. The hypothesis that was made had mostly incorrect predictions‚ but with some correct ones. It was found that using the palm of one’s hand was the best surface on which to melt chocolate‚ as was predicted. It melted so far‚ and so fast‚ that the experiment had to be altered. Coming in second place was the surface of black paper‚ something that was not expected. The black

Do your results support your hypothesis‚ use date from your table and graph to support your answer‚ you should also identify any anomalous results. My hypothesis was ‘as the surface-area-to-volume ratio decreases the diffusion rate increases’ my results support my hypothesis‚ because in my table of results when the surface area to volume ratio is at 14 the diffusion
