Hi this is me Hana and me and my partener Jia have taken dirty water and made our own filter out of a sertain amout of material, i am about to tell you what I used and felt about this project.
Materials: duck tape, cotton ball, popsicle stick, cardboard tube, cloth, rubber band, plastic water bottle.
I think engineering is important because if yoiu think abou it most of the things in the world we have today ise engineering. For examplethe chair that you sit on has been design and engineered by someone, or maybe the computer you use at school everyday has also been engineerd.
The biggest challege I came across in this project was trying to get the yellow out o the water. It didn’t fully come out but it got alot lighter than before. At first we got all of the big chunks of dirt out but then the tiny mollecules who just go through our design.
