**9. Fruitfulness**

Fruitfulness is the final stage of conceptual change theory. Any new concept designed needs to benefit learners as this would allow them opportunities and exposure to real-life circumstances, thus leading to future-content learners, as argued by Posner et al. [9]. Following the demonstration, learners continued to discuss the events associated with chemical reactions and energy concepts. The main goal of these discussions was to demonstrate how functional and effective the newly learned concepts were. Learners seemed to have accomplished these experiments as they shared their real-life experiences extracted from occurrences from their immediate and diverse environments.
