The National Parks Board (NParks) is the latest national agency to help children learn in environments outside the classroom.

On Wednesday, NParks worked with 237 schools to participate in the annual international Green Wave. This is a project by the United Nations to educate children and youth about the importance of protecting the natural environment.

At 10am in their respective time zones, students from all over the world including Singapore planted trees in their compound.

PAP Community Foundation (PCF) Fengshan was one of the school participants. A total of 41 children in the preschool watered and shovelled soil for three pre-planted saplings.

The kindergarten's principal Wong Woon Chian said the exercise provided basic exposure to planting trees and such a hands-on activity was in line with what they learn in the classroom.
