A case is described of the development of a lesson plan for 10th grade (age range 15-16) chemistry classes on the chemistry of shower gels. The lesson plan follows a socio-critical and problem-oriented approach to chemistry teaching. This means that, aside from learning about the basic chemistry of the components making up modern shower gels in…

This paper describes the development of different lesson plans dealing with authentic and controversial socio-scientific issues in the framework of climate change. These lesson plans orient themselves along the socio-critical, problem-oriented approach to science teaching. They deal with the use of bioethanol as an alternative fuel and with the…
