Developing Arguments About Human Impact Using Expedition: Learn!
Teaching argumentation skills addressing real-world environmental issues in today’s classroom isn’t easy. Between sorting fact from opinion, getting caught up in conflicting information (or battling disinformation and misinformation), and getting students to back up their claims with actual evidence (not just “I saw it on TikTok”), it can feel like an uphill climb.
That’s where Expedition: Learn! comes in. Our science lessons and hands-on activities guide students to critically analyze data, collaborate with their peers, and construct strong arguments based on evidence and scientific reasoning—helping them understand not just what is happening to our planet but why it matters and what we can do about it.

Take a look at how our experts use the featured lesson, Human Impacts on Earth Systems, to explore content and craft effective arguments rooted in scientific best practices—just in time for Earth Day and beyond.
Help Students Understand Why It Matters
Earth Day, celebrated every April 22, reminds us of our responsibility to protect the planet. With a world population of more than 8 billion people, caring for Earth can’t be just a one-day event. It must be an ongoing effort that requires understanding our environment, recognizing human impact, and taking action to minimize harm.
Earth’s systems interact. Human activities such as deforestation and pollution disrupt these systems and their interactions, leading to consequences such as habitat loss, extreme weather, and water shortages—all symptoms of climate change. By researching how our actions affect the planet, we can make informed choices to create change.

In an age of information overload, it’s difficult to decipher what’s accurate and what’s not. Equipping students with the skills needed to think critically and make arguments based on research and evidence is crucial. These skills, of course, lead to academic success. But more importantly, they help shape well-informed members of society who can advocate effectively for our planet.
