Searching for Ancient Oceans on Mars

SciShow Kids

Join Anthony and his robot mouse friend Squeaks as they explore the Red Planet and the fascinating mission of the Perseverance rover. This engaging science video breaks down how scientists use robotic explorers to study Mars, specifically looking for evidence that the dry, dusty planet once hosted massive oceans of liquid water. Through clear comparisons between Earth and Mars, the video explains complex geological concepts in a way young learners can easily grasp. The content focuses on three main scientific themes: space exploration technology (rovers and helicopters), states of matter (water as ice vs. liquid), and geology (erosion and landforms). Viewers learn how scientists use 'Earth analogues'—like the Grand Canyon and river deltas—to interpret mysterious features on the Martian surface. The video visually demonstrates how water shapes land, explaining how ancient riverbeds and shorelines on Mars provide clues to its watery past. For educators, this resource is an excellent tool for connecting Earth science concepts to planetary exploration. It naturally bridges lessons on landforms, erosion, and the water cycle with excitement about space technology. The visual explanations of how deltas form and how erosion works serve as perfect introductions to hands-on stream table experiments or comparative planetology units.
