World Soil Day World Soil Day (WSD) is held annually on December 5 th. Observance of this special day creates awareness about the importance of soil for the ecosystem and overall well-being of all creatures. Bubbles organised an activity for the same, where the teachers explained about the vitality of soil and how it helps to grow different crops. Later our creative Bubblites prepared beautiful miniatures of mother earth on a sheet and paid their gratitude.
