Explaining the importance of clean water to a young child is too abstract and complex a concept. Besides, in developed countries, its hard to find people who dont have access to clean water. The Little Treasures Pure Water Science Kit allows a child to see directly how water thats dirty can become clean through the process of filtration! Description: Including everything thats needed in order to create a water filtration and purification system, the Little Treasures Pure Water Science Kit is easy to use for children who are ten years of age or older. The safe and non-toxic materials of the kit are easy for a child to assemble, with virtually no help from an adult! Learning biology and Earth Science can only help a child move further with their education.
