Today the Year 7R science class successfully separated a mixture of salt, sand, rice and iron filings. We used a range of methods of separation including seiving, magnetic separation, filtering, decanting and evaporation and crystallisation. All the images have been saved in a folder called “Separating Mixtures” in the year 7 Science folder on the Student Public drive. Use these images to create a Photostory (with audio) or a PowerPoint (with text) describing the procedure you used to separate the materials and how successful you were in collecting pure materials. How would you improve your method if you did this experiment again? How were some of the materials lost?
See Katie and Chloe’s PowerPoint of the process they used here.
