IYC Experiment 3 - Solar Still Challenge

How does our water become contaminated?

In this activity students will make a solar still and measure its efficiency. They will develop their understanding of water in liquid and gaseous states and how distillation can be used to purify water. They will be challenged to design and make a more efficient still.

A diagram and photograph of the most efficient solar still made in their class will be reported to the Global Experiment Database together with the efficiency data.
