Mixing two substances together is a physical change. Even though the appearance may change, the two substances do not form a new substance and can be separated. Today we looked at methods of separating mixtures.<\/p>\n<p>I gave each group of students three different mixtures:<\/p>\n<ul>\n<li>marbles and beads in two sizes<\/li>\n<li>sand and salt<\/li>\n<li>cornmeal and iron filings<\/li>\n<\/ul>\n<p>and challenged them to try to figure out how to separate them using any combination of the following tools:<\/p>\n<ul>\n<li>a sieve<\/li>\n<li>a slotted spoon<\/li>\n<li>a coffee filter<\/li>\n<li>a magnet<\/li>\n<li>a funnel<\/li>\n<li>a cup of water<\/li>\n<li>a stir stick<\/li>\n<\/ul>\n<p>It was interesting to observe the ideas each group came up with and how they worked together to revise their plan when something did not work out.<\/p>\n<style type=\"text\/css\">\r\n\t#foogallery-gallery-588 .fg-image {\r\n
