In this activity, Grade 7B students made a solar still and measure its efficiency. They developed their understanding of water in liquid and gaseous states and how distillation can be used to purify water. They challenged to design and made a more efficient still. The results of their work and the efficiency data are reported to the Global Experiment Database.
During the preparation and discussion of the experiment, Grade 7B students in Shajara School build a solar still in science lab and find out how it can purify water. Also Grade 7B students are challenged to use their knowledge to build a more efficient solar still. They asked to do that as home activity.
