[Catalist] water filters

[FISHER Scott [Esperance Senior High School]]

Home-made clay/coffee ground water filters  worked well as an investigation

Info here as an ABC story 2005
http://www.abc.net.au/catalyst/stories/s1381331.htm

Simple recipes available around the net, but basically to make a simple filter  mix equal parts clay and water into a paste, shape it in a cup. Let it dry and fire it.


Cheers

Evening All
I am after an investigation for year seven students where they can make their own water purification model.  If anyone has any designs that would be appreciated.

Many thanks,
Teresa Bulich
