Hi Guys! I am Jia and this is a project Hana and I have been working. The project is called ‘Water Filter’. The purpose of this project is to remove unclean things, such as dirt. Our filter is made out of bottled water. We just cut the plastic water bottle into half and put cotton balls in the drinking section. (There is nothing in the cardboard tube) We had two days to experience this project. The first day, we just had to put dirt water inside the filter. The second day, the dirt water became much dirtier and unclear. So we had to filter it for more than four times. In the end, we used popsicle sticks to soak up all the dirty things, such as small dust. The 4th picture is what happened on Day 1. The 1st to 3rd is Day 2’s.
