Matter+and+Mixtures!

In this unit, we will be looking at the structure and properties of matter. We will investigate changes of state, and chemical changes. We will then look at different types of mixtures, and techniques for separation.



__Key words__

**Solid, liquid, gas, particle, compress, expand, contract, condensation, freezing, melting, evaporation, mixture, filtration, solvent, solute, filtrate, filter funnel, crystallization, evaporating dish, decantation, conical flask, seiving, distillation, distillate, condenser, melting point, boiling point, soluble, insoluble, separation funnel, chromatography, chromatogram, stationary phase, mobile phase, solvent front, qualitative analysis, quantitative analysis**

**__ Student tasks __**



**1.** ** a. ** Create new One note section called 'Matter and Mixtures' b. Create a page called 'States of Matter'. **c.** Search the Internet for diagrams of the states of matter, solids, liquids and gases and paste them onto your page. **d.** Now describe what is different about the particles in each diagram and try to explain how those differences relate to how solids, liquids and gases feel to the touch. (You can use specific examples if it helps- e.g. a desk, water, wind on your face) **e.** Discuss your ideas with a partner.

**2. Go to:** [] Work your way through the interactive applet about changes of state (according to the Particle Theory of Matter) to the end. Copy the questions at the end on to your wiki page, research and record the answers to each one and compare your responses with others in the class (choose two people) by using the discussion button on the top of their page. In your discussion, make a comment about how easy their explanations are to understand and if they are not easy to understand, tell them how they can improve. Continue to define key words in your glossary.

3. [] Look through the chapters you need to revise and then take the revision test. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 120%;">Next go to : []

Copy and paste these questions to your student page, think carefully about your response and investigate if necessary then answer them as fully as possible. <span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 120%;">1. Why do icebergs float in antarctic and arctic waters? Do you think there is much of the iceberg under water or is it mostly above the water? How could you test your hypothesis? <span style="color: #008000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 120%;">2. When you have a jar with a very tight lid, you can run it under hot water and it becomes easier to open. Why?
