ObjectivesDescribe the physical and chemical properties (magnetic,
conductivity, melting/boiling point, reactivity) of a pure substance using your senses and tools Using the Kinetic Theory illustrate and account for solids, liquids and gases in terms of the arrrangement and motion of molecules |
ActivitiesDiscussion starts with an understanding of properties and how these properties
define matter. Properties determine not only the identity of the matter but how these properties affect the behavior of the matter. Use four items to generate discussion about their physical properties and how this determines their use in society. Use the wiki discussion forum to have students express these properties and explain the importance to the functionality of the product. View the Physical property chart within the Physical Properties powerpoint and address therole of thermal conductivity, state, malleability, ductility, solubility and density. Use the Wiki to respond to a question related to these physical properties. We will use the forum to interact and reflect on how physical properties are important to understand the behavior of matter. Quiz over physical properties Address chemical properties by viewing Chemical Properties powerpoint. Use examples from the slides to discuss how these properties affect how the matter is used. For example, a car with its issues of rust and how plating is used to overcome this problem. Also, the movement to plastic products which will not oxidize in the presence of oxygen and water. Discuss the chemical properties in world landmarks and how these properties lead to the breakdown of the landmark. To better view this breakdown, click on the following links for pictures and Google Earth to zoom in on the following landmarks: Statue of Liberty Great Sphinx of Giza Eiffel Tower Roman Colosseum Gateway Arch Culuminating Assessment: Quiz Culuminating Assessment: Research an existing landmark and describe its physical and chemical properties. Hypothesize as to how this landmark could have been redesigned based on these properties to exist over a longer period of time. Create a Wiki page to display your findings. Landmark word document United streaming video and questions. http://player.discoveryeducation.com/index.cfm?guidAssetId=6994C0DC-BE6E-46BB-80A8-615B5B25D45C&blnFromSearch=1&productcode=US Introduce solids, liquids and gases using Bill Nye Matter Phases. Discuss the content of the video with the class. Next, discuss the arrangement of molecules in solids, liquids and gases and their movements using the website States of matter. The idea of particle movement can be enhanced with the Stadium Crowd website. Discuss additional characteristics of solids, liquids and gases using the website Solid, liquid an gas animations Have student groups use the computer to observe the Harcourt Publishers Part 2 animation. As these groups watch the animation, require the groups to explain the purpose of the animation. The questions will address the arrangement of molecules for each state and how this arrangement changes as matter goes from one state to the other. Assessment: Use wiki discussion forum to address questions about animation. Wiki of the Day scoring guide will be used. Assessment: Generate quality question about this objective. (arrangement and motion of molecules in solids, liquids and gases). Quality Question Scoring guide will be used. Evaluation: Use ranking tool to rank group questions based on their quality. |
