Titel 1 Alkanes and alkenes

Crime scene:
               Focus on doing experiments:
                                    -colour and Vis-absorption spectrum
                                    -ethanol content and colour change of permanganate
                                    -ethanol content and fire (what is the minimum ethanol content in a mixture with water that is need before it can be set alight).
                      Experiments are used for logical deduction, to talk about qualitative and quantitative experiments and to teach variables (independent, dependent and controlled).


Alkanes and alkenes
            Used as a model system to get a chemistry language.
                       model descriptions: building models of molecules, strucutral formulae (a number of representations), molecular formula.
                       reactions: combustion, substitution, addition.
               Correct terms and ability to switch between macroscopic observation and microscopic model descriptions.

          Experiments: complete and incomplete combustion, reaction bestween hydrogen and oxygen, reactions of bromine with alkane/-ene.
