For Earth Day, Oak Grove Elementary kindergarten students recycled and repurposed unwanted items into their very own Litter Bugs. The Litter Bug project is an Earth Day STEM activity focused on conservation where students use recycled materials to create a piece of art. After creating the Litter Bugs at home, students presented them to their class and discussed what items they reused for their creations. Earth Day is a perfect time to bring the Litter Bugs to life as spring is when bugs start buzzing about.
