Looking for an engaging way to spark meaningful conversations about environmental issues leading up to Earth Day or just how humans impact the environment? This Earth Day Countdown Class Starter Bundle gives teachers an easy, low-prep way to get students thinking, talking, and collaborating around real-world environmental topics.

Each day, students analyze a powerful image related to an Earth Day or environmental concept—such as deforestation, plastic pollution, water scarcity, fast fashion, climate change, and more. Students discuss 3–4 guiding questions in small groups before coming together for a whole-class discussion. These prompts are designed to encourage critical thinking, perspective-taking, and respectful discussion.

The images are clear, work well across all grade levels, making this resource flexible for elementary, middle, and even high school classrooms.

How It Works

1. Project the daily slide on the boar
2. Students discuss the guiding questions in small groups (3–5 minutes)
3. Bring the class together for a whole-group discussion using the provided teacher discussion key

Perfect for:

• Bell ringers
• Earth Day countdowns
• Social-emotional learning discussions
• Science, geography, or social studies connections
• Morning meetings
• Exit tickets if you'd rather do it at the end of class
