Solar-Powered Water Desalination
Ocean water is too salty to drink. But a process called desalination can turn seawater into fresh water that people can drink. With this environmental science kit, you will make a solar desalination device that uses a power source that is free—the sun!
This science project kit contains all the materials you need to build a working desalination chamber without making trips to multiple stores. We've gathered all the hard-to find pieces, like plastic boxes and funnels that are just the right size, the right weight washers, a beaker, and a graduated cylinder, in one simple kit. We've even pre-drilled the holes in the rectangular boxes and cups so you will spend less time setting up the experiment and more time enjoying the results! How much desalinated water can the device produce, and is the water still salty at all? Will the color of the bottom of the chamber affect its performance? Use this kit to answer these questions and more!
This kit follows the procedures from the Science Buddies environmental science project Solar-Powered Water Desalination.
