You can incorporate Earth Day activities and ideas into your whole day. Here are some ideas to get you started.
Incorporate Earth Day into your lesson plans. Spelling, vocabulary, math and science can all be used to focus on Earth Day.
This site has some great resources for lesson plans: http://www.earthday.org/knowgreen-lessons
Take a field trip to a recycling plant, nature preserve or science museum to learn about preserving our planet.
At lunch time discuss the different ways we can recycle, and take care of our planet when we purchase, prepare and consume food.
Have kids bring in recycleables and then create with them. Provide basic craft supplies and let them go crazy. For younger kids plan a project and guide them. Some ideas are egg carton critters, plastic bottle bird feeders, and glass jar piggy banks, the options are endless.
Have kids work on a large scale project, a report, a speech or demonstration. Incorporate Earth Day messages, lessons and ideas into the project.
