Abstract: Successful students have a continuous motivating cycle of reflection, connection, confidence and positive self-esteem. Therefore, it is imperative for an educator in an academic institution to create a positive and encouraging environment that enhances students learning and personal fulfilment. We fabricated a Roof – type Solar Water Distillation (RSWD) kit which was tested under actual environmental conditions of Urualla, an ancient town in the Eastern part of Nigeria. The system includes four major components; a rectangular wooden basin, an absorber surface, a glass roof and a condensate channel. All the components were obtained from our local environment and the RSWD was able to generate 2.3m3 of distilled water within six days. This is a successful practical application of the principles of thermal absorbance, evaporation and condensation. Obviously, a successful practical experience ensures deeper understanding of the subject and sustains student interest.
