Finally the activity reinforces the meaning of a soap and an understanding of its cleaning action.
Zero Emission Carsfor – Is It Feasible?
This set of activities allows students to consider factors which can be involved in determining the use of vegetable oils in a diesel engine, its cost effectiveness, cleanliness for use and finally the ethical aspects of whether it should be used this way. The activities also allow students to devise tests for determining the calorific value of fuels. Finally the activity reinforces the meaning of an ester and its presence in biological materials.

Traffic Accident: who is to blame?
A boy was knocked down by a van on a pedestrian crossing linked with traffic-lights. The boy was slightly injured. A reconstruction of the accident was undertaken in an attempt to determine blame.
This series of lesson assumes that the students are familiar with the laws of motion, but explores the possibility of introducing the idea of friction by an examination of skid marks related to an actual traffic accident. The students are thus introduced to the coefficient of friction through trying to solve an actual societal problem.
