Its about how the resistance of a wire increases with the length of the wire. I got good results and a few are anomalous. I just don't know hat to conclude and evaluate about it. All my teacher has said is to add scientific explanation and i just have, but i would be 6 marks short. I need to know hat things to consider to write or even what to write. Any help will be appreciated and a bset answer lol. P.S I am at GCSE standard. Thanks

I see you have no answers, so i can try my best! I am only 14 myself, and i am unsure of what you want to know...what is the marking criteria?
You need to sum up something like 'the longer the wire, the higher the resistnance' or whatever. Also include how you have anomolous results, which you are going to ignore, and draw a graph and say what the graph shows (eg a strong positive correlation between...)
You need to explain why, and include anything that you think is neccessary (i am not sure-molecules, etc??) and explain WHY it happens.
Im sorry but i really cant think what to write.
Could ou ask for help from one of your classmates and see what they have put?
Good luck!

i did that one for my coursework aswell.. i cnt remeber but you have to write about the relation between the two and show your results. You say that the anomilies affect your graph and things like that. and critiaclly analise your experiment saying what you could have done to make it better or better equipment you could have used e.g. if you did it on a computer or manually, and how it could have affected your results.
hope u havn't already done them and good luck!! i think i scored a 6665 on mine

I would really like to hellp you but the only thing i know about physics is when i've had too much to drink. and i have a touch
of them!!!
