Chemistry

A) What question were you trying to answer and why?    A) The question we were trying to answer was "Which changes are examples of a chemical change, and which are examples of a physical change?". The reason why we were trying to answer this questions was because we needed to know that we saw something different in the experiments that wasn't there before. B) What did you do during your investigation and why did you conduct your investigation in this way?  B) During the investigation we had a handful of different experiments that we conducted. The first one included a small ball of copper and required a bunsen burner. You would then place the small copper ball into a ceramic holder and as the copper ball began to heat up it changed color which made a chemical change as it turned to a silver/black color which meant it was no longer copper. The second experiment was simple with warm water and salt and you would then pour the salt into the water which made a physical cha
