Students are working on creating their own water filters this week. Various supplies were provided, such as 2 liter bottles, nylons, gauze pads, cotton balls, rubber bands, tape, sponges, fish tank gravel, coffee filters, and straws. Students examined these supplies and then began by researching water filters and creating a blueprint of their own. Students were also responsible for explaining, in their own words, how the water filters will work. Once their design was approved, they collected their supplies and started building.
