A. The scientific principle behind step A is all to do with burning the seaweed and turning into ash. To do this it had to be done with a Bunsen burner which was on the blue flame so it was at its hottest to turn the seaweed into ash. B. In step B the scientific principle is the filtration of the purified water. The reason for the ash being boiled was to extract the iodine ions. D. The scientific principles behind step D was the adding of hydrogen peroxide solution to the remaining

Techniques in Forensic Science Abstract Since 1985‚ DNA profiling in forensic science has become very important in this virtual era of technology and in the world of science that solves both major and minor crimes. Small traces of DNA are considered in all circumstances from how the DNA was collected to fully obtaining the profile in its significant form. Traces of sweat‚ blood and semen are the most common type’s evidence found at crime scenes. There are several different methods for creating

BIO 110 Lab 1 The Scientific Method Exercise 1 1. Based on the information in Table 2‚ the patterns I observed were that were 2ppm of Dissolved Oxygen added each time and there was 1 fish less than the amount of Dissolved Oxygen‚ then 4 fish less‚ then 3 fish less‚ then 4 fish less‚ than 5 fish less. I think that the fish can handle the amount of Dissolved Oxygen to an extent then the population falls‚ but then starts to build back up. I also think that if the population is a bigger number

Methods of Research Research‚ systematic inquiry aimed at the discovery of new knowledge‚ is a central ingredient of the scientific method in psychology. It provides the key to understanding the degree to which hypotheses (and the theories behind them) are accurate. Just as we can apply different theories and hypotheses to explain the same phenomena‚ we can use a number of alternative methods to conduct research. In this exercise‚ you will learn more about several methods of research that psychologists

S1 Beginning with Science 02: Scientific Investigation Scenario 1. 2. Describe why the investigation above is not adequate to explain what types of rocks will dissolve in water. They need to use the same rocks from the backyard. You can’t compare different types of rocks. Just because it appears to shrink doesn’t mean it actually did. You need real data of what the mass of the rocks were before the rainstorm. 2. Using what Christopher and Kate have already observed‚ suggest a possible hypothesis
