The GLOBE Program
1. Providing a common platform to interact with the students and teachers on environmental issues.
2. Helping a lot in spreading and disseminating environmental knowledge and concepts to large number of people.
3. Providing "Hands-on Environmental Experience" on environmental concepts to the students to carry out various measurements.
4. Motivating students to learn about scientific protocols by performing environmental learning activities, which are already introduced as theory in the greened textbooks.
