CHEMISTRY – Great job lighting Bunsen burners today! By the way, did you happen to see a green flame when you put the copper wire in the flame? The electrons in the copper atoms were being excited and they gave off a green flame. Cool!!
Here’s something you will find useful in the future…everything you wanted to know about a Bunsen burner and how to light it. Be sure and view the slide show BEFORE you take turn in your lab sheets and take the test.
