On Tuesday, we made water filters.We tested different materials to see what worked best to filter the really dirty water. Mrs. Guevin made filthy, disgusting, mucky water. The class collected old two liter soda bottles and reused them to make the filter container. Remember, always reduce, reuse, recycle! We used sand, cotton balls, screens, rocks and paper coffee filters. We all agreed that sand worked the best for cleaning the water. Some children found that using cotton balls with sand also had a cleaning effect. We used the Engineering design process!
First, we asked a question: "How do we clean the water?" . Then we imagined how to make a filter for the water. Next, we made a plan by drawing a diagram. Then we created it using the diagram. After, we made improvements to our design. We wrote in our science journal what we observed and wondered.

ReplyDeletestudent 23: We had really fun and a lot of people's water filters worked pretty good. Some of mine didn't work as well and I think a lot of people enjoyed it.
ReplyDeleteStudent 22: I want to say that the water filters some of them put cotton balls first and then they put sand and it made it clear.
ReplyDeleteStudent 25: We had a lot of fun making the water filters. Some of the water got a little bit messy, but the sand got messy too and we had a lot of fun making it. We could do it again its just its gonna take a lot more practice and it won't be as much fun if we do it twice.
ReplyDeleteStudent 19: I liked making the water filter because I like to clean water. And that day we had so much fun and I thank my teacher for letting us make water filters.
ReplyDeleteStudent 21: It was fun and cool.
