A group of students in Clearwater is tasked with finding a solution to a problem. They start by researching various water purification methods, looking into filters, boiling methods, and modern techniques like reverse osmosis. They also explore energy sources that could help make the process more sustainable, including solar power, since their town gets plenty of sunlight.

After weighing the pros and cons of each possible idea, students choose to build a solar distillation system. It uses simple materials like glass, black plastic, and mirrors to harness the sun’s energy and purify the water through evaporation and condensation, effectively removing contaminants.

Which step of the EDP is this?

• Ask

• Imagine

• Create

• Plan

The students gather materials and build a prototype:

• A clear, slanted glass panel on top of a black plastic basin filled with contaminated water.

• Sunlight heats the water, causing it to evaporate.

• The vapor condenses on the glass, drips into a collection tray, leaving contaminants behind.
