Students will explore an alternative way of purifying water using a solar still, learning about the distillation process and the states of matter. The activity will provide students with the opportunity to design and build their own more efficient stills.
- The experiment has been tested with students across the different levels of schooling.
- The experiment addresses the important chemical concept of states of matter that is addressed at primary and both junior and senior secondary levels of schooling. The experiment can contribute to student’s learning about the global water cycle.
- Ancillary concepts include the important idea that many substances, both good and hazardous, can be present in water but not visible.
The materials required for the experiment are all readily available and hence only the instructional materials would be required for distribution.
