While humans require food all year, many factors affecting food availability are beyond their control, such as climate and natural life processes, so food preservation is required to ensure the quality and longevity of food. In the subject PBL, under the theme Food Preservation, students of Grade 5 participated in finding ways to preserve food items, ranging from early methods of salting, pickling, and dehydration to more recent pasteurization techniques, food additives, etc. and freezing. Prior to exploring, students were first engaged in observing and predicting what happens to the various food items over time, such as What changes did they notice? What were the environmental conditions (light, heat, and water) that affected food? Subsequently, students were encouraged to conduct interviews with their parents and grandparents as well as gather information on Google to investigate food preservation methods. This project was perfect for assisting our fifth-grade students in exploring scientific methods of research on Food Preservation methods.
