The ocean covers about 71% of Earth’s surface, making it one of the most important parts of our planet. It supports marine life, influences weather and climate, and provides food and other resources for people around the world.
🐠 A giant home for life
The ocean contains an enormous variety of living organisms, from tiny microscopic creatures to enormous whales. Scientists continue to study ocean ecosystems to better understand how they function and how they are changing.
Learning about the ocean can also help students understand biodiversity, climate, pollution and conservation. NOAA provides educational resources covering topics such as corals, tides, marine life and Earth’s systems.
🌡️ The ocean and climate
The ocean plays an important role in Earth’s climate system. Changes in ocean temperature can affect marine ecosystems, weather patterns and communities around the world. Educational programs encourage students to examine real ocean data and investigate how changing conditions affect wildlife and ecosystems.
🧪 Learning through experiments
Ocean science doesn’t have to be limited to textbooks. Students can investigate subjects such as sea-level rise, ocean temperatures and ocean acidification through experiments, data analysis and classroom activities. NOAA’s educational resources include hands-on lessons designed to help learners connect science concepts with real-world situations.
🌍 Why ocean education matters
Understanding the ocean can help young people become better informed about environmental challenges. It can also inspire future scientists, engineers, conservationists and other professionals.
The big lesson: The ocean isn’t just a place to swim or fish—it is a huge part of the Earth’s life-support system, and understanding it helps us understand our planet.
