You separate solutions all the time: cooking, sorting money, laundry ! Mechanical Sorting separate parts of a mixture based on properties such as particle size – Ex: Floating, magnets Filtration removing particles by filter paper – Ex: Brita Water Filters ! Reading Check 281 - #2,3 – Evaporation a liquid turning to a gas solute is left behind – – Simple Distillation removing a solute and solvent from each other. Solution is heated until the – solvent changes state to become a gas. Then the gas changed back to a liquid by cooling. Example: See photos on page 283 Chromatography separate the colored substances in a mixture such as ink. – CORE LAB 287 289 – – Checking Concepts 291- #1,2,6 – Activity Students Read pages 292 294 – – Reading Check 294 - #1,2 – Checking Concepts 297 - #1,2,7,8 – Activity Students choose 6 questions they want to do on pages 300-301 –
