The concept of food management inspired the students to collect information from their parents and grandparents. They learnt and shared simple recipes especially those that can be whipped up with leftovers! They also told the visitors about “Happy Fridge” placed by the Government, where we can deposit any excess food that can go to people in need.
Students created awareness on the sugar content present in soft drinks by boiling the soft drink. The visitors could clearly see the sugar content. The students were enthusiastic to share natural homemade recipes of pizza sauce and peanut butter. This was a yummy project.
Wastewater treatment is a process used to remove contaminants from wastewater or sewage and convert it into an effluent that can be returned to the water cycle with minimum impact on the environment. This is called water reclamation wherein treated wastewater can be used for other beneficial purposes.
