Insulating materials

Extracts from this document...


Insulating materials Science coursework Candidate name: Anisah Habib Candidate number: 4042 Introduction: For this piece of science coursework I will be investigating what materials are best as insulators and what ones are worst. The materials I have chosen to use for this experiment are bubble wrap, foil and tissue paper. I will test all these to see which one would be the bet insulator when I pour water in a hot can as the insulator would be wrapped around the can therefore I will check the temperature every so often to find out which is the best insulator. Aim: my aim is to find out if different types of insulating materials can prevent heat loss from a tin can of water. Prediction: I predict that bubble wrap would be the best insulator on the can. Because I think the material will be good at trapping the heat molecules and not letting them escape therefore the can with the bubble wrap material wrapped around it would stay hot. Scientific evidence: A conductor is something that lets energy flow through it. When heat travels through solids it so called conduction some materials are better than others. A poor heat conductor is a good insulator. ...read more.


However if it did loose a lot of heat this means it's a bad insulator and that it doesn't trap heat. Variable: I will keep the amount of water the same for each can as if I don't it is not a fair test and would probably create anomalies in my graph. The things I would vary are the insulations materials for example bubble wrap, foil and tissue paper. Safety: While I am doing this experiment I must make sure my work bench is clear so that if the water spills it doesn't affect anything or anyone. I also will wear goggles to stop the heat going to my eye when pouring the water in the can or when pouring the water in the cylinder. Another is I have to be careful when I am handling the water as I don't want to burn myself this has to be doe carefully. As when I am carrying the water I don't want to drop it. Fair test: To make my experiment a fair test so my results are reliable and consistent I will keep the following things the same: * Use the same amount of water for each experiment with different amount of insulation wrap * Use the same size wise of insulation wrap so one can doesn't have more insulation then the other. ...read more.


Evaluation: I think my experiment didn't go as well as I think I could have because I think my method wasn't appropriate enough. Therefore if I was to do this again I would redo my method before I carried out my experiment. I also don't think my experiment was a fair test because after my first test the water cooled down and then we boiled again the same water where we should have used fresh water each time. Again I think this was down to the method. If I was to do this experiment again I think I would draw up and to another method and use fresh water each time to make it a fair test. Other then this I think my experiment went well as my graph doesn't show any anomalies this shows that my results are reliable and consistent. Because I measured my results accurately as possible. Overall my results support my prediction as bubble wrap was the turned out to be the best insulator. It was the best insulator as the bubble wrap material trapped the heat molecules in the material therefore keeping it warm and preventing any heat loss. ?? ?? ?? ??

Response to the question

The aim/question of the coursework is to find out if different types of insulating materials can prevent heat loss from a tin can of water. The terms ‘insulating material and heat loss’ are clearly defined with response to the question, which shows the candidate understands the purpose of the experiment. The candidate also gives a good answer to why they think bubble wrap is the best insulator as opposed to the others, which also shows a good response to the question and a high level of understanding. As the question is an aim, the candidate responds to it excellently using appropriate investigation techniques such as writing the methodology, apparatus...etc. This shows the candidate has thought their response to the question through sufficiently and scientifically, hence aiding their answer to the question.

Level of analysis

There was a high level of analysis throughout the coursework, especially using scientific evidence, which itself was supported through use of diagrams. A visual analysis is particularly useful to use in coursework, especially when a candidate is trying to get a more complex point across to the examiner, so in my opinion this worked well. There are also fairly length paragraphs for both the analysis and evaluation, which shows the candidate has intricate knowledge about insulators. However, the paragraphs did seem to lack why the scientific reason for the results they obtained, although this was discussed before it would have been better to see that the candidate fully understood their results. The candidate did however, explain in detail how the impact of some variables not making it a ‘fair test’, which was excellent as it showed that the candidate understood contributing factors to how well a material can insulate a metal can.

Quality of writing

The quality of writing did bring my rating of the whole coursework down, especially since the candidate did not use a single comma, which shows they lack in written communication skills. There were also unnecessary repetitions of phrases within a single sentence, for example, ‘I think my experiment didn’t go as well as I think I could have because I think my method wasn’t appropriate enough’. Which showed that possibly the candidate found it hard to get their points across. But overall the coursework was very well structured, with clear subheadings for the ‘aims, predictions, results..etc’ and this boosted my rating of the coursework. There is good scientific terminology such as ‘variables’ and especially in the definition and description of insulating materials, however ‘reliability or accuracy’ could be used instead of ‘fair test’, to show a broader use of scientific knowledge which the examiner is looking for.

    This means that it needs 4 electrons in order to become stable and in order for the zinc to do this, it has to displace the copper sulphate from its sulphate in order to produce zinc sulphate and copper. This reaction is very fast.

    Periodic table

    Unstable isotopes disintegrate to form other substances which are radioactive. Some atoms are naturally radioactive; others have to be made active and are called artificial. The energy emitted by radioactive substances is called nuclear radiation. 3 types of nuclear radiation: Alpha - alpha particles are helium nuclei that contain 2 protons and 2 neutrons.
