The first Earth Day in 1970 inspired an astonishing 20 million Americans to take to streets and college campuses in protest of air and water pollution, loss of wilderness, and animal extinctions, all legacies of the rise of industrial society in the 19th and 20th centuries. Out of this impressive public outcry came the Environmental Protection Agency and legislation to protect air, water, and endangered species.
While we’ve made some strides in controlling pollution and preventing the extinction of marquee species such as the bald eagle and California condor, the concerns of 1970 are very much still with us. Even worse, we now understand that climate change due to human activity is a threat that must be addressed within this century to prevent massive upheaval of societies across the globe.
The following free Earth Day lessons and activities will help teachers explore this crucial subject with K-12 students in an engaging, age-appropriate way.
