My Own Filter
To end off our science chapter, “Material Changes”, for the term the Year 6 students explored how to make their own filtration system. Their goal for this activity was to discover that ground materials can clean and purify water before it is returned to the surface.
The criteria for the investigation was that their filter system needed to be durable and easy to use, have three layers and the layers needed to be made of ‘natural’ materials that they could find in their yards or nearby park. They could also make use of recyclable materials.
Let’s see what the Year 6’s had to say about their experience:
I really enjoyed my filtration project. It was so fun making the filter because you had to make important decisions on how you were going to layer your materials. It was really fun and I hope we get something like it again. – Maia Davies
What I liked most about the project was collecting all the materials especially the gravel because people were looking at us very weirdly. I enjoyed all of it and it was a great experience. – Glanville Morgan
What I enjoyed the most was experimenting with the different materials and finding out if they filtered the water. Knowing that a material that I tested worked and filtered the water made me fill with joy. I learnt that if natural filtration did not exist most of the fresh and clean water we have would be dirty. I also learnt that different materials have a different impact on how it changes the water. – Saumya Maharaj
I enjoyed making the actual filter, choosing what to put inside it and what should go in first. I learnt about how natural items ,like sand and rocks, can actually clean dirty water and about how charcoal removes toxins from dirty water without removing important minerals. – Faith Chivaka
The thing that I have enjoyed the most was how filtration works. We have learnt that the filtering system removes redundant or unwanted particles in dirty water. Filtration is a process used to separate solids from liquids using a filter medium that allows the fluid to pass through but not the solid. – Teeyana Shaik Mahomed
We would like to congratulate our students for doing a phenomenal job at completing this project.
