Please create coloured pie graphs to show 97% salt water and 3% freshwater for grade 5 science students

This resource explores the concept of Earth's water distribution, emphasizing the fact that about 71% of the Earth's surface is covered by water, with a critical distinction between saltwater (97%) and freshwater (3%). It highlights the importance of understanding the sources of these water types, where most freshwater is found (glaciers, lakes, rivers, and groundwater) and why conserving this limited freshwater is vital for human survival and agricultural needs. The document includes data representations, guided questions for deeper engagement, and an activity for students to create their own water distribution graph using given data. Additionally, the resource prompts reflection on the reasons we must conserve our freshwater supply.
