HowToFunda was founded with the reasons that students, teachers, and parents were struggling to make the school models during the school or science exhibitions due to the complexity involved in making the model which is a hard nut to crack. In the current education system, the term science exhibition refers to science projects, science presentation and implementing the science working models as prototypes, which students to exhibit the learning made by the students. The science exhibition is a very important event to help the student to prepare towards science projects. The science exhibition helps the students in improving the presentation skills and also increases the interest in science or any other subject. Being the parent myself did not find the right content or information on the school project model in one place.

Smart Automated Waste Segregation Dustbin(WET and DRY)
