Modeling Earth's Water Reservoirs: Frozen vs Liquid fresh water

Detailed Description

Earth is known as the "Water Planet," and each of these 100 gummy bears represent 1% of Earth's water. This activity encourages students to think about how much of Earth's water is salty (96.5%), how much is not salty (fresh = 3.5%), and how much of the fresh water is solid (68.7%) vs liquid (31.3%).
