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!

Each kit contains: 

 2   Clear plastic rectangular containers with predrilled holes
 2 Plastic cups with pre-drilled holes
 1 Graduated cylinder, 25ml
 1 Beaker, tri-pour 800 ml
 1 Stick of Modeling clay
 1 Thermometer, 6", C scale
 2 Funnel, small, 5 ml
 2 Straw, flexible
 2 Washer, flat, steel, 7/16
 2 Rubber band
 3 Construction paper, black, 8 1/2" x 11"
 3 Construction paper, white, 8 1/2" x 11"

Instructions for this kit are available online, see Additional Information for links to the instructions and more.

Convenient and easy to assemble
As a parent, very convenient if you have limited time to gather supplies. My son was able to assemble and perform experiment without supervision.
