Chemistry learning how to use a bunsen burner

In this lab, students used a copper strip to test which part of the flame was the hottest.  At the hottest part, the copper will have a green flame in just a second while in other portions, there is no flame until 2 or 3 seconds.  Students also learned how to transfer solids from a weigh paper to a test tube, that measuring liquids needs to be done with a graduated cylinder and not a beaker, and how to adjust the bunsen burner to get a blue flame.  Incomplete combustion was also discussed and the evidence was shown when they created an orange flame on the bunsen burner and held an evaporating dish over the flame observing a black coloration on its bottom.
