Appendix 1:
Working Individually and Collaboratively
During this practical I have had to work collaboratively with my partner during the experiment and individually while writing this practical report. While conducting the investigation, I had to work with my partner in a safe and considerable manner to allow the experiment to be completed safely. The person that I was collaborating with poured the hydrogen peroxide solution into the measuring cylinder with the liver it and marked the froth volume, while I timed the whole procedure. We both kept an eye out on the temperatures of the water baths and the temperature of the kidney and solution inside the test tubes so that one person didn’t have to watch all of them. This allowed more precision …show more content…
If the liver is touched and then benches, objects or food is touched as well, they can become contaminated with the liver and could possibly make people sick. This can be avoided by wearing gloves as well as washing hands after the experiment. The surrounding surfaces can also be cleaned in order to minimise the chance of the surfaces being contaminated. Another risk is the glass equipment. The glass beakers, test tubes and thermometers are fragile, so if they are dropped, the shards are hazardous and could potentially severely injure somebody. The breakages could be avoided by keeping all of the glass equipment in the center of the bench, rather than the edges where they could be knocked off easily. If glass is smashed, injuries can be avoided by wearing inclosed shoes, warning others to be careful in the area and cleaning the glass up straight away in a safe manner with hand broom, rather than picking it up by hand. The sharp knifes used to cut the liver could also be a potential risk. The liver has to be cut into very small cubes, and since the liver is very slippery, there is more of a chance of slipping and being cut, which could be avoided by keeping fingers away from the knife. If the knife is left on the edge of the counter. Especially with the blade’s point facing outwards, somebody could potentially walk into it and severely injure themselves. This could be avoided by leaving the knife in the centre of the benches and also being careful of surroundings as to not walk into a knife if left dangerously on a bench. In the experiment, hot water up to 50°c is being dealt with, therefore precautions need to be taken so that is not spilled otherwise people could be burned. This risk could be minimised by not leaving beakers of hot water on the edges of benched. Injury could be avoided by wearing the laboratory waterproof aprons and enclosed shoes. If hot
