This paper analyses ideas around students' understandings of chemical reactions, which is the focus of this lesson. Energy changes in chemical reactions is an abstract concept that many people continue to struggle with past Junior Cycle. In my lesson, I have a large focus on the areas in this paper which have been highlighted through research as 'problem areas' for students.

This article highlights the importance of student participation in the classroom, which I embedded into my lesson plan. Students must be included in the class to fully engage in their learning. This also ties into Wellbeing, which has a key role in the Junior Cycle, as it allows students to feel connected and respected in the classroom setting.
