Introduction __**

This topic is a study of the very basics of Chemistry. Your study of Chemistry begins with the study of matter, which is something that occupies space and we can detect with one or more of our senses. First we will review your understanding of solids, liquids and gases and add to your knowledge by investigating what makes them different on the atomic level. We will study how substances behave under certain conditions as we assign physical and chemical properties based on these studies. We will use these properties of substances to learn techniques for separating mixtures. This is a unit for uncovering the mysteries of the micro world, so put on your lab coat and clean off those safety glasses as we begin ur study of Chemistry! **

**__ Student tasks __**


 * 20 May 2009 -** **1.** Create a link on your student page for this new topic. **2.** Search the Internet for diagrams of the states of matter, solids, liquids and gases and paste them onto your page. **3.** 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). **4.** Discuss your ideas with a partner.


 * 28 May 2009 - go to:** []
 * 1.** 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. **2.** Continue to define key words in your glossary.
