The context-based learning approach is an innovative strategy that places real-life contexts at the center ofeducation. An important strategy developed within this approach is the REACT strategy. This study aims tocreate an activity plan based on the context-based approach, especially following the REACT strategy, for thetopic 'Transformation of Electrical Energy' in the 8th grade 'Electric Charges and Electric Energy/PhysicalPhenomena' unit in the Turkish National Education curriculum. Additionally, students' opinions regarding theimplementation were taken. The qualitative research method was adopted in the study. Firstly, the learningobjectives related to this topic were determined. Taking into account the learning outcomes of the topic ofelectrical energy transformations, an activity plan was created that meets the purpose of each stage of theREACT strategy and allows students to learn with real life contexts. Feedback was received from two middleschool science teachers and a physics education academician regarding the suitability of the prepared activityplan for the REACT strategy and 8th grade science. The initial plan was refined based on their input addressingissues such as incomplete implementation of collaboration, mismatch between context topics and subject matter,limited student assessment, and suggested time adjustments. The final activity plan was shaped according tothese suggestions. The completed lesson plan was piloted and feedback was received from the students. Thestudents gave feedback that the lessons given using the REACT strategy were motivating due to their relevanceto daily life, that they were fun, and that they were different from other lessons because they included activitiesand more group work.
