Problem Statement: Human activities in agriculture, industry, and everyday life have had major effects on the land, vegetation, streams, ocean, air, and even outer space. One major effect is fresh water becoming more scarce. Due to water scarcity, people need to find new ways to conserve and protect freshwater sources.
Students will:
Research and learn about water scarcity on planet Earth
Listen to experts and synthesize new learning in their presentation
Visit places to obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment
Create a prototype or visual to illustrate their solution to the problem
In teams, orally present their solutions with their prototypes to a panel of expert
