Separating Mixtures Virtual Lab

Introduction Yesterday we learned that there are many different ways we can separate mixtures. Since mixtures are a combination of multiple different substances we can use physical changes in order to complete these separations. We use the physical properties of these substances to do so. Before we get started with the virtual lab let's remember the different between physical and chemical changes and properties Pre-Lab Questions Physical and Chemical Properties Sort these properties into either chemical or physical Chemical Reactivity with Acid Ability to Rust Flammability Physical Solubility Magnetism Density Boiling Point Chemical and Physical Changes Sort these changes as either chemical or physical Chemical Burning Fuel Rusting Physical Phase Change Dissolving Recrystallizing Classify the following Substances Substance Pure Substance or Mixture Element or Compound (if Pure Substance) Homogeneous or Heterogeneous (If Mixture) Baking Soda (NaHCO3) Pure Substance Compound Arsenic (As) Pure Substance Element Chocolate Milk Mixture Homogeneous Soil Mixture Heterogeneous Lab Introduction You will be completing a virtual lab that has three specific challenges. You will be complete each challenge and have questions that go along with it. It is VERY important that you read the instructions on both this wizer as well as on the website. Separating Mixtures Click the above in order to go to the virtual lab! Link to virtual lab! Mixture One This mixture is made up of Iron Filings, Salt and Fine-Grained Sand.You will need to use the equipment in the equipment shelf in order to separate the mixture. Before you start you should brainstorm the properties of each of the materials that you can advantage of! What are the properties of these materials that you will use to complete your separation? Complete the Separation As you complete the separation make sure you are paying attention to the order that you complete the steps because you need to write it down! What was your first step and what did it remove? What was your second step and what did it remove? What was your third step and what did it remove? What was your fourth step and what did it remove? Mixture Two This mixture is made up of Lentils, Salt and Pepper.You will need to use the equipment in the equipment shelf in order to separate the mixture. Before you start you should brainstorm the properties of each of the materials that you can advantage of! What are the properties of these materials that you will use to complete your separation? Complete the Separation As you complete the separation make sure you are paying attention to the order that you complete the steps because you need to write it down! What was your first step and what did it remove? What was your second step and what did it remove? What was your third step and what did it remove? What was your fourth step and what did it remove? Mixture Three This mixture is made up of Safety Pins, Glitter and Beads.You will need to use the equipment in the equipment shelf in order to separate the mixture. Before you start you should brainstorm the properties of each of the materials that you can advantage of! Complete the Separation As you complete the separation make sure you are paying attention to the order that you complete the steps because you need to write it down! Write down your the Procedure you completed Write down the steps that you took to separate the different substances. Make sure that you are specific in order to earn full credit! Post Lab Questions How did you decide on the order of your procedural steps? Would any order have worked? Application Question How could you separate each of the following two-part mixtures Mixture Separation Method Lead Filings and Iron Filings Sand and Gravel Sand and Glitter Iron Filings and Glitter Phase of Matter Match the state of matter with the description Solid Lowest energy molecules. Barely move just vibrate in place Liquid Molecules have some freedom, and can slide past one another Gas highest energy molecules and the molecules move to fill the whole container What is the boiling point of this substance based upon the graph? 801 1465 0 134 Congratulations! You have finished the classifying matter unit! Make sure you finish up any missing assignments! Next week we start atomic theory! :)
