From recycled snowflakes to pinecone bird feeders to upcycled winter lanterns, these three K-5 Sustainable STEM activities bring holiday magic into the classroom while keeping environmental stewardship front and center.

Inspired by the book "Miss Makey and the Magic Bin," this multi-day STEM challenge turns recyclables into student inventions. Through the Engineering Design Process, kids learn that yesterday's trash can become tomorrow's treasure.
