Today in class you tested 5 different substances for 3 properties: whether they’re magnetic, whether they float, and whether they dissolve in water. Tonight for homework, you need to write out a step-by-step procedure for tomorrow’s Separation of Mixtures Lab. You need to come up with a detailed plan for how you’re going to separate a mixture of salt, sand, black pepper, pebbles, and iron filings. Write your procedure on the next blank page of your science notebook, and include a list of all materials you’ll need.
