I am fairly sure that they used animal bones to hold the copper over a hot fire and when it started to melt they moved it over the soapstone mold someone who may be in your class... because I had this exact question for homework except in french.... Also in case anyone wants to know the melting point of copper, it's 1084.62 Celcius, 1984.32 Farenheit, 1357.77 Kelvin for those who know what this means, 7-7.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
