Earth’s WaterIs that all?
Information and pictures from USGS “Water Science for Schools” Website

-I did a demo with 100 M&M’s to represent 100% of Earth’s Water. If the students guessed the correct percentage of water available for human use they get to eat that number of M&M’s -The correct answer is 1/100 of an M&M (basically a fleck from the candy shell).
