The document outlines classroom activities focused on environmental education for different age groups. For 3-4 year olds, students participated in a recycling workshop where they learned the names of recyclable objects and sorted them into bins for paper, plastic, and aluminum. 5 year olds discussed ways to save the planet and created a display. Primary students sang a song about litter, participated in plays about recycling, and created displays about the "5 Rs" - reduce, reuse, recycle, react, and respect. The goal was to raise awareness about environmental issues.
