It was Volunteer Day at school so the students were asked to serve the community. Class 4A visited a preschool nearby. They taught the kids some fire safety precautions with games and role play. Class 4B went to an animal hospital. They refilled bowls with food and cleaned cages. The students worked hard and fast. So, the hospital staff let them wash the pretty puppies. Lastly, Class 4C stayed at school. They recycled plastic bottles and removed fallen leaves on the playground. All students learned something from this precious experience.
