Original PromptUnit 3: Earth’s Interactive Systems
Unit Overview
In this unit, students investigate the Hydrosphere and its dynamic role in shaping our planet and sustaining life. By analyzing data, conducting hands-on experiments, and applying mathematical models, students will discover that while water covers most of the Earth, the portion available for human use is remarkably small.
The curriculum moves from global water distribution to the powerful ways water reshapes the land, concluding with an evaluati...
This learning resource focuses on the hydrosphere and global water distribution. It aims to help students analyze the distribution of water on Earth, highlighting that approximately 97% of the planet's water is salt water found in oceans and seas, while only a small fraction is fresh water available for human use. Students will learn to identify human impacts on water quality through pollution, urban runoff, and conservation methods such as reducing, reusing, and recycling water. Additionally, the resource explores the geological processes driven by water, including erosion and deposition, which shape landforms and create features like deltas and alluvial fans. By engaging in various activities, including mathematics applications for water volumes and observational comparisons between water features, students will display a deep understanding of how water functions within our ecosystems.
