Free printable conservation and endangered species lesson plans for Earth Day

Hello my friends of the Omschool! Are you enjoying your Spring Break and Easter holidays? In this lovely month of April, we celebrate Earth Day, which replaces the original holiday Arbor Day (Tree Day). For the past years April has also come to be celebrated as Earth Month, culminating with official Earth Day, April 22 on the Spring Equinox. 

To explore this important holiday, here's a free printable environmental science and endangered species booklet Save our Species, with information, activities and coloring pages exploring endangered species in the US. The purpose of Earth Day is to celebrate our earth, educate people and explore ways to protect natural resources. Protecting our earth includes supporting our animals, plants, habitats and ecosystems. Earth Day reminds us that we rely on the earth for sustenance and the earth relies on us for care and safety. 

Understanding endangered and threatened species helps us to learn better ways to care for our environment as a whole. The EPA has developed a free printable 28 page environmental science activity and coloring booklet entitled Save Our Species. This free printable endangered species resource book is perfect for Earth Day. It has been developed for and provided to the public as an educational information guide. On Earth Day, and all Earth Month, students can explore endangered and threatened species in the United States, by coloring the animals, plants and habitats. 

This free printable environmental science activity book can be used as a field guide or zoo field trip planner. This booklet includes free printable coloring pages of endangered species and threatened species (species whose habitats are being encroached upon and destroyed). It explores 16 species of endangered animals in the United States and five threatened species.

Spotlight: The Black-Footed Ferret

One highlight of the Save Our Species booklet is the Black-footed Ferret. Once thought to be extinct, this resilient creature is making a comeback through careful conservation efforts. Sharing success stories like this in the classroom offers students a sense of hope and shows them that environmental protection really works!

Here's a unit on animal extinction lesson plans which explores the annihilation of the passenger pigeon population. This planned extinction is unique in endangered species in that it happened so quickly. An entire bird species was wiped out in a matter of years. Here is a website called Revive and Restore which endeavors to de-extinct lost species. So far, the gene editing process has not been successful which shows just how true is the maxim "extinct is forever." 

John Ball Zoo, in Grand Rapids, Michigan has extensive free printable Zoology lesson plans. There are science lesson plans on migrations, animal habitats, conservation and a host of other animal related activities. Featured animals are monarch butterflies, penguins, lions, chimpanzees, hummingbirds and more. 

Local Spotlight: The Eastern Massasauga Rattlesnake

In our own backyard near Grand Rapids, the John Ball Zoo is doing vital work to protect Michigan’s only venomous snake. The Eastern Massasauga is a "threatened" species that relies on our local wetlands. Teaching students about these misunderstood neighbors is a great way to explore local biodiversity and the importance of habitat preservation!

Additionally, local initiatives in Native Planting to boost populations by planting Michigan-native species Eastern Hemlock or Spruce, in schoolyards or home gardens to support local wildlife. Michigan has struggled with invasive species, some of which, like purple loosestrife, were planted as ornamental flowers and ended up taking over wetlands and destroying the entire ecosystem. The golden loosestrife beetle was introduced to eradicate this rampant invasive species. Replanting original native species helps restore balance to Michigan's precious natural resources, including the precarious dune structure. 

These free printable environmental science resources make an excellent Earth Day tool for classroom, homeschool, scouting, 4H and any organizations dedicated to the preservation of natural resources. The website includes a free printable Save Our Species poster and lesson plans for teachers and homeschoolers. Decorate the school hallway for Earth Day by assigning each student to color a certain number of endangered species images. Place a large map on the wall and arrange endangered and threatened species pictures around the map with arrows pointing out areas to which the endangered species is native.

Use these endangered species lesson plans to raise awareness to our vital yet fragile ecosystems and to the importance of protecting them. Here is a final thought from teacher Omi who has loved the Lake Michigan dunes and beaches for decades. 

Dune Icon: The Great Lakes Piping Plover

If you’ve ever walked the beaches at Sleeping Bear Dunes or along the West Lake Michigan shore, you may have seen areas roped off with "psychological fencing." These protect the nests of the Piping Plover, a tiny shorebird that is a true conservation success story. Once down to just 17 pairs in the 1980s, the population hit a record 88 nesting pairs in 2025! These birds are so well-camouflaged that they look like "stones with legs." Protecting their nesting sites doesn't just save the birds; it preserves the wild, undeveloped beauty of our dunes for everyone to enjoy.
