Water Filter Testing

Last term for inquiry we created our own water filters to improve the state of dirty water.  We worked in small groups, to research how to create filters using a small amount of materials. I worked with Taheesha, Eyaka, Marieta, and Alex. Following our plan, we used charcoal, dirt, grass/gravel, cloth, and our bottle. Our water improved slightly when we compared it to the grading strip probably because we were missing the proper material we needed. And it seem like it wasn't going to work by how fast the water was filtering.
