It’s April, which means you’re expected to save the planet between morning announcements and lunch. Here’s how to teach actual conservation without turning your classroom into a literal junkyard.


Start Here: Try a Simple Prompt

Try these Earth Month conservation science lessons and DIY activities for grades K-2, Whether you're looking for a Earth Day or Earth month resource.

Ask your students where their trash goes after they toss it in the bin. Write down what they say.

Most will tell you it just “goes away” or magically disappears into a giant hole in the ground where it turns into dirt. 

Here’s the fact that makes them pay attention: Every piece of plastic ever made still exists in some form.

Try telling a 2nd grader that the juice box straw they used in preschool is currently sitting in a landfill or floating in the ocean, looking exactly the same as the day they used it. That’s the moment the “away” in “throwing it away” loses its magic.

Grades K-2: Sorting the Mess

At this age, “the environment” is a big and abstract word. They need to see that their specific choices, like which bin a yogurt cup goes in, actually matter.

Grades K-2 Natural resources 

Students need to understand that they use natural resources for everything they do. Take the time to go over the importance and how natural resources are used every day.
