Introduction to Science

In the first few lessons we were briefed on the rules of the laboratory and what tpe of apparatus is there in the laboratory , but the one that I found the most interesting was the bunsen burner as until we touched on that I thought flames were just flames and were all the same.I learnt what was luminous flame and non-luminous flame.Luminous flame is unsteady and it is not very strong as compared to the non-luminous which is strnger and steadier.Also we learnt about the Bunsen burner and strike back.Strike back occirs when too much aoir is present.
