Water Distribution Across Our Planet

Ms. Slayton introduces the flipped classroom model, allowing students to watch the video multiple times and take notes at their own pace. The video covers the distribution of Earth's water, highlighting that 71% of Earth is covered in water, with 97% being saltwater and only 3% freshwater. The breakdown of freshwater shows that most is frozen or underground, with a small percentage available for human use. The video emphasizes the importance of water conservation and provides a visual pie graph to illustrate the distribution of Earth's water.
