With World Water Day just around the corner, on the 22nd of March, Life is a Garden has put together an engaging water filtration experiment for the whole family. Get the kids involved and  teach them about water pollution and how to get clean water.

Living in a drought-stricken country, water is a very precious resource. Sadly, many South African’s do not have access to clean water. Teaching  kids about the importance of water in agriculture is an essential aspect of education and will help youngsters understand just how critical H2O is for  a healthy environment.

This fun science experiment teaches kids about the importance of clean drinking water. It also demonstrates the process of how to clean dirty or polluted water using a natural filtration system.

You can make a water filter using recycled materials found at home. This water experiment is appropriate for kids aged ten and up, and can be used during science class or as a hands-on, educational experiment at home.

You will need the following supplies:
  • Two glass jars
  • Fine, clean sand
  • Gravel or small stones
  • Rocks
  • Coffee filters, cotton balls or a small cloth
  • Activated charcoal
  • Clear plastic bottle
  • Dirty water
  • Scissors or a knife
 Instructions

1. Cut an old plastic soda or juice bottle in half using scissors or a knife.

2. Place the bottle upside down into the glass jar..

3. Place cotton balls, cloth, or a coffee filter inside the bottle as the first layer. The first layer should be about two to three centimetres thick.

5. Over the charcoal, add about three centimetres of fine sand as the third layer.

6. Add about three to four centimetres of gravel or small stones on top of the fine sand.
