Celebrate Earth Day With Citizen Science

It’s April: Citizen Science Month! There are hundreds of online events and ways to engage, including many opportunities from libraries around the world. Looking to do some projects inside and around your home? Check out the projects below. Then, discover additional events and opportunities on CitizenScienceMonth.org.

For more than 50 years, Earth Day has been a chance to step back and look around at the world around us — and then give back to our home planet. Beginning Tuesday, April 20, volunteers around the world will unite to take care of the Earth. You can join them by participating in citizen science projects that study, explore and seek to understand our often fragile environment. We’ve gathered five of our favorite Earth-tastic projects for you below. And don’t forget to add projects you love to your Project Dashboard.

Debris Tracker

We all see debris everywhere around us every time we go outside. Now, you can turn those sightings into real data with Debris Tracker. Add to the millions of pieces of debris already tracked around the world.

Land Loss Lookout

Louisiana’s wetlands are being lost at an alarming rate: more than 400 square miles have already vanished. Help scientists monitor this fragile habitat from anywhere by scanning aerial photos and calling out blighted areas.

NYBG Virtual Herbarium Expeditions

What’s a herbarium, you say? Glad you asked! Come explore a collection of unique plants, collected by thousands of botanists over hundreds of years. This online project asks volunteers to study and categorize plant (and fungi and algae) life from all over the world from the comfort of their own home.

Stay Home: Household Waste Audit

We can’t talk about Earth Day without talking about trash. And, speaking of garbage, do you know how much you’re actually throwing away each week? Find out with this kid-friendly citizen science project that tallies up household trash.
