1. Bike Powered Water Purifier Concepts: Fluid Mechanics, Water Conservation Equations: Experimental Challenges: Create and test bike powered water purifier Analytical Challenges: Determine which filter best used to filter water, measure pressure, flow, and gear ratio http://umaine.edu/met/capstone-projects/2013- various/clean-water-project/

2. Challenge Analytical: Students design water purifier powered by a bike by determining what type of filter is required to best filter water with the least amount of particles while maintaining a specified flow rate and pressure Students can vary the gear ratio on the bike, regulate the flow of water, and pressure Experimental: Students build the water purifier that they designed and simulated.

3. Student Experiences Theory behind module is useful in the real world to help third world countries that are plagued with micro-bacteria in their drinking water Topic outside of the students’ normal learning
