Teaching Aids	a) Textbook b) Reference book
Reflection	Students have no problems with physical properties of alkenes. They are able to describe the effects on boiling points of alkenes due to increase in the number of carbon atoms in alkene molecules. They also able to relate this trend with alkane molecules. For chemical properties, students have o problems except for addition of hydroxyl group. This is because they confuse with the naming of the product formed from the reaction. However, teacher explains several times to make sure they understand better and able to do the exercises. Teacher gives hands on activity to evaluate their understanding.
