cleaning up dirty water is fun!

Our task was yo clean up dirty water. 

We used a variety of filters, sieves and containers to separate a mixture of salt, sand and water. The sand was easily removed by passing the mixture through the sieves and the filter paper. Now we had to get rid of the dissolved salt. We did this by evaporating the water using tin foil trays and night lights. We now know that the mixture can be separated successfully. Our next task will be to recover the water by condensing the vapour back to liquid water. We really learned a lot about recycling water from this activity. It was great fun... highly recommended!!!
