    Im doing an experiment on how the length of a piece of wire affects the resitance. I know that the longer the length themore resistance becuase the electrons have further to travel causing more collisions when they are trying to complete te circuit. Im on my conclusion, and i need a much more detailed explanation for al this rubbish!!! Geez, i hate all this work!

    talk about the thickness of the wire, the material of the wire etc etc

    Err i just realised how crap my spellin was. Soz. Erm ive basically wrote about the patterns on my graph n how the resistance is proportional to the length. I need a detailed explanation why it is tho.

    i didnt experiment with ether of those. i basically need to write a detailed conlusion on why te length of a wire affeced the resistance. i need to go into more detail than 'the electrons have to travel fuher causing mor colisions between them and the atoms'

    For some reason 'Being Ugly' and 'God' are included in that list?! Maybe there's some off topic talk in them (?).

    ANALYSING EVIDENCE
    Explain simply what was shown by the evidence
    Use simple graphs / charts / diagrams to help explain evidence Identify trends or patterns in the evidence
    Use graphs (line of best fit) charts, diagrams or numerical methods to process evidence for conclusion
    Draw conclusions from evidence and explain using scientific knowledge and understanding
    Use detailed scientific knowledge and understanding to explain valid conclusions from processed evidence
    Explain how conclusion supports or undermines original prediction

    EVALUATING EVIDENCE
    Relevant comment about procedure or evidence obtained
    Comment on quality of evidence and IDENTIFY unexpected / abnormal results (anomalies)
    Comment on suitability of procedure and suggest improvements
    Comment on reliability of results and whether the evidence is enough to support a firm conclusion. Account for anomalies
    Describe, in detail, further work to provide additional (extra) relevant evidence

    if you can i need a detailed conclusion on the resistance of a wire. i only got four days to hand in my coursework and you said it was easy. i just need a conclusion

    The resistance of a wire is directly proportional to the length, but inversely proportional to the cross sectional area of the wire.

    Do you learn R = ρl/A at GCSE (where ρ = resistivity, l = length, A = cross sectional area)?
