The methodology proposed in Chemie im Kontext was followed and adapted with project-based learning to ensure key concepts were assimilated and related to students¡¯ everyday life. In such a way, the focus was drifted to a student-oriented approach in which students used the scientific method to inquire about the way in which cleaning products work from a chemical perspective. A collaborative approach was conducted to deliver a scientific poster that portrayed their work. http://pubs.sciepub.com/education/9/6/2/education-9-6-2.pdf ChiK context-based learning project-based learning collaborative approach scientific method chemistry of cleaning inquiry-based learning
