Free Earth Day Crack the Code & Printable Activities
Earth Day is celebrated on April 22nd each year.
It is a time to reflect on how we treat the planet, cleaning up our spaces, and planting new trees. The planting new trees and flowers is my favorite.
The “biggies” in my life taught me to clean up any area that I spent time in outdoors. Cleaning up after other people and the trash they leave behind has been a habit since I was little.
I can NOT walk past a piece of trash.
Recycling, Reducing, Reusing, and Composting have been big themes in my life as well. These are also great areas to get children involved.
Reusing is always a really great lesson in the classroom and crafts with uncommon items will spark discussions and a ton of creativity. It is also a great time to incorporate some STEM lessons.
