4. INTRODUCTION What Is A Water Filter? A water filter is a device that purifies water by removing impurities and contaminants, improving its safety and cleanliness. It can use physical, chemical, or combined methods to achieve this. Water filters are used in homes, businesses, and industries to meet specific water quality standards and needs.

5. WHAT DOES THE WATER FILTRATION DO? .Valuable natural resources on Earth .71% of Earth’s surface .Example of natural sources of water: Rainwater, River , Groundwater , Lakes , etc.

6. Including Four Layer

7. First Layer : Cotton .Falling into the clean water container .Block and filter out larger parpiculates

8. Second Layer : Sand .Remove all the suspended matter, as well as floating and sinkable particles .Improve the colour , taste and odor of the water

9. Third layer : Small Stones . to remove dirt and debris from water,making it cleaner to use .Helps removing the poor taste and discoloration

10. Final Layer : Big Stones .Keep the filter media stable and prevent it from shifting or clogging,ensuring smooth water flow . Preventing the smaller filtering materials from moving around and blocking the flow of water. This ensures effective filtration.

13. Steps To Make A Water Filter Step 1 : Prepare some cotton, large stones, small stones, sand, a plastic bottle, and two PVC pipe. Step 2 : Cut the plastic bottle and divided into two sections. Step 3 : put the cotton at the bottom of the plastic bottle.Then , put the sand on it ,followed by small stones and lastly big stones. Step 4 : Make a hole at the top and bottom of the plastic bottle to facilitate the installation of the PVC pipe. Step 5 : Cover the other cut section of the plastic bottle to the first section. Step 6 : Direct the dirty water into the filter and see the result.

14. Why Did We Choose This Design??? . this design allows each component to have its specific function. .This design is cost-effective because it utilizes environmentally-friendly materials.

15. Rajah di atas menunjukkan alatan dan bahan yang digunakan semasa proses penurasan air. Antaranya adalah seperti air keruh 1500ml, bikar berbentuk silinder , corong penurasan berbentuk kon dan bahan seperti arang (a), batu kecil (b), dan pasir (C) digunakan sebagai 3 lapisan penurasan.Ketinggian kon adalah ½ daripada ketinggian bikar silinder .

16. Jika nisbah ketinggian bahan yang digunakan sebagai lapisan penurasan adalah sama , cari ketinggian lapisan pasir . Jawapan : 1/2 × 30 = 15 cm 1/3 × 15 = 3 cm Setelah melalui proses penurasan , hanya 90% sahaja air yang terhasil . Berapakah isipadu hasil turasan ?  Jawapan : 90% daripada 1500ml 90/100 × 1500 =1350ml/cm³

17. iii) Seterusnua cari ketinggian air ( hasil turasan) di dalam bikar tersebut.Bundarkan kepada 2 tempat perpuluhan. (π = 22/7) Jawapan : Isipadu Silinder = π j²t 1350 = π j²t 1350 = 22/7 × 10² × t 22/7 × 10² × t = 1350 t = 1350/10² × 7/22 t = 4.30 cm iv) Bagi membolehkan hasil turasan selamat diminum air perlu dididihkan.Jika Selepas proses pendidihan , ketinggian air dalam bikar berkurang kepada 4 cm, berapakah isipdu yang telah tersejat ? Bundarkan kepada 2 tempat perpuluhan . ( π = 22/7) Jawapan : Ketinggian yang hilang = 4.30cm - 4.00 cm = 0.30 cm Isipadu air yang tersjat = 22/7 × 10² × 0.3 = 94.29 cm³
