- 1. EDTECH 522 Adult Online Learning<br />Blackboard Mini Unit Project Periodic Trends<br />Thu, Jul 22, 2010 -- Welcome to Chem 001! Welcome to Chemistry 001! This course explores the fundamentals of chemistry specifically elemental properties, structure, bonding, along with matter and measurement. Each week is broken down in to units which will cover particular topics. In each unit you will receive links to online reading materials, video presentations, interactive models, and assessments. The units will open and begin on Monday, with quizzes being completed by Wednesday and weekly projects turned in by MIDNIGHT on Sunday. There will be discussion boards with weekly questions which students are required to participate. If you have any questions you can either email me or post your question on the discussion board under the questions category.I look forward to working with each of you and seeing the work you can produce throughout the course.Steven Poast<br />Assignments <br />Periodic TrendsUnit Lesson - Periodic Trends of AtomsOverview: The Periodic Table contains many patterns and trends involving the electron configurations of the elements. In this unit we will explore how certain properties of elements change as we move across periods or up and down groups. By being able to identify these patterns and trends an individual can make educated predictions about chemical and physical properties. After reading over the Objectives, youreview the assigned Readings/Videos/Presentations, participate in the online discussion, complete the review quiz (not graded), complete the graded online quiz by Wednesday (midnight EST) and the writing assignment by Sunday (midnight EST).Objectives: Students will...Review assigned reading and view assigned videos/presentationsCompare and contrast atomic sizes of elementsDefine Ionization Energy, Electron Affinity, and ElectronegativityPredict the key periodic trends of Atomic Radii, Ionization Energy, Electron Affinity, and ElectronegativityIdentify periodic group properties with their respective elementsCompose a story using one of the three prompts describing the characteristics and trends of elements.Activities:Review class online readings Complete online review quiz for review of periodic trendsCompleteonline quizParticipate in discussion(s)Compose element story from prompts (see description below in Assignments section)Resources:Each resource may contain more information than is needed for this unit. *Only review the sections relating to Periodic Trends, Atomic Radii, Ionization Energy, Electron Affinity, Electronegativity, and Group Properties.Online Materials:Periodic Trends:Online Readings:http://www.learnchem.net/tutorials/trends.shtmlhttp://www.sparknotes.com/chemistry/fundamentals/atomicstructure/section3.rhtmlhttp://www.sciencegeek.net/Chemistry/chempdfs/PeriodicTrendsOrganizer.pdfVideo/Presentations:http://www.wou.edu/las/physci/ch412/Periodic trends/periodic_trends.htm*(scroll half-way down the page to Periodic Trends.

Email your completed assignment to Mr. Poast by midnight Sunday (EST). stevenpoast@u.boisestate.eduScenarios:1. Survivor/Lost: You are stranded on a desert island with no hope of rescue. What elements do you want stranded with you and why? These can be descriptions of the elements themselves or they could be characters that have the element traits (see example). Pick four or more elements for your story.2. Superheros: League of extraordinary elements. Crime has run a muck in our fair city! Who will save us from danger? Create a league of elemental superheros who will come to our rescue. Describe each of their superpowers. Be sure thata superhero'spower reflects its properties. Pick four or more elements for your story.3. Create your own scenario. Use your own creativity and develop your own scenario including four or more elements. Student scenarios must be submitted and approved by Mr. Poast no later than Thursday.<br />Discussion Board<br />ForumTotal PostsUnread PostsTotal ParticipantsGradeWhat are trends?Trends - the general direction in which something tends to move. As in he/she follows the latest trends. Trends exists everywhere. For this discussion name a type of trend and how it impacts our world. Be descriptive in your explanation of your trend. Why is it a trend? Has it always been a trend? When did it become a trend? Will it stay a trend?Be sure to comment on the trends your classmates discover.<br />Marie Curie<br />Chemistry 001<br />Mr. Poast<br />Rock Band<br />This season in music there have been many one-hit wonders, Idol favorites that fizzled, and bands that tried to make a comeback but never did. It seems the fans have been more demanding than ever since the pool of musicians has expanded; these days, anyone with a voice can make a record! However, one group has shined above the rest. They put the metal in heavy metal. Their recent songs, Atomic Love, I Chemically Bonded to You and High Conductivity were all Billboard #1 hits. Today I sat down with the hit band, Elemental, to discover their unique properties and the secret to their explosive success.<br />As everyone knows, Fluorine, the lead singer, is VERY attractive. This, of course, is due to his high electron affinity; in fact, no element is higher! Fluorine can attract more electrons than any other element. (It has been rumored that he bonds to many of them as well!) However, dont think he will stick around for very long, ladies, his non-metallic vaporous characteristics make him dissipate quickly! Fluorine has the typical lead-singer-of-a-rock-group look - very skinny. Fluorine has one of the smallest atomic radii of the periodic table. However, when he is about to bond, his ego gets inflated quite a bit; his ionic radii is almost double that of his atomic radii. Its obvious to see why he is so popular!<br />On lead guitar is Gold. Very flashy and brilliant in nature, Gold obviously stands out on stage. His talent is considered by some to be precious. Gold has the unique ability to play his electric guitar without an outside power source, because he is such an excellent conductor himself! Unfortunately, Golds attitude has been something of a problem of late. He sees himself as very rare and valuable, even though there are many other elements worth more than he. Gold also seems to consider himself untouchable because of his limited reactivity. Very few substances can form a compound with Gold. While this can give him a sense of entitlement, it has also lead to loneliness.<br />Every good band needs its backup support, and Elemental is no exception. Lithium is the element behind the scenes, working as their head roadie. Lithium has a lot of experience with this type of music, being highly metallic himself. He also can keep up appearances for the Elemental entourage, since his silvery color is so trendy right now. His conductive properties also come in handy with technical and electrical malfunctions during shows. Lithium is very co-dependent however, and cant exist on its own. He is frequently seen with the usual Elemental groupies, typically Hydrogen, Sulfur and Oxygen. Unlike Lithiums soft qualities however, Barium, the groups bodyguard, is all muscle. He is one of the hardest and densest elements, and really keeps his cool under pressure (his melting point is rumored to be very high). He almost seems to repel electrons, but he actually just cant attract them very well due to his low electron affinity, and reportedly loses them easily due to his lower ionization energy. He also is a force to be reckoned with, having large metallic characteristics and one of the largest atomic radii in the periodic table. I wouldnt want to meet him in a dark alley!<br />Although all of the members of Elemental are very different, they all seem to work together well as evidenced by their numerous chart-toppers. They each follow the beat of a different drummer, blazing their own periodic trends, but together they set the standard that others follow. The various properties and characteristics make them a veritable reactor of talent.<br />RUBRIC<br />Top of Form<br />Criterion PoorFairGoodContent & Development 50 pts Poor (0-15 pts)- Content is incomplete.- Character features are not clear and there is only mention of two or less elemental characters.- No sources are used Fair (16-35 pts)- Content is not comprehensive and three to four elemental characters are presented.- Character features are addressed, but not well supported. - Research is inadequate (1-2 sources) or does not address course concepts.- Content is inconsistent with regard to purpose and clarity of thought.
