8G SEAL Flame Test Practical

8G SEAL students began their chemistry unit with the flame test practical.  They had wooden sticks that had been dipped in unidentified metal solutions.  Based on the colour of the flame, they were able to identify which compounds contained sodium, copper, strontium, and other metals.   They learned that the colour of the flame is caused by electrons jumping energy shells when heated, and each metal will have a different pattern of colours in the visible spectrum of light.
