ChemMatters Reading Strategies * December 2017/January 2018These graphic organizers are provided to help students locate and analyze information from the articles. Student understanding will be enhanced when they explore and evaluate the information themselves, with input from the teacher if students are struggling. Encourage students to use their own words and avoid copying entire sentences from the articles. The use of bullets helps them do this. If you use these reading and writing strategies to evaluate student performance, you may want to develop a grading rubric such as the one below.ScoreDescriptionEvidence4ExcellentComplete; details provided; demonstrates deep understanding.3GoodComplete; few details provided; demonstrates some understanding.2FairIncomplete; few details provided; some misconceptions evident.1PoorVery incomplete; no details provided; many misconceptions evident.0Not acceptableSo incomplete that no judgment can be made about student understandingTeaching Strategies: Links to Common Core Standards for Reading:ELA-Literacy.RST.9-10.1: Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions.ELA-Literacy.RST.9-10.5: Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g.,?force, friction, reaction force, energy). ELA-Literacy.RST.11-12.1: Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account.ELA-Literacy.RST.11-12.4: Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to?grades 11-12 texts and topics.Links to Common Core Standards for Writing:ELA-Literacy.WHST.9-10.2F: Provide a concluding statement or section that follows from and supports the information or explanation presented (e.g., articulating implications or the significance of the topic).ELA-Literacy.WHST.11-12.1E: Provide a concluding statement or section that follows from or supports the argument presented.Vocabulary and concepts that are reinforced in this issue:Metric unitsStructural FormulasFermentationpHElectrochemistryOxidation & ReductionAminesAllotropesPhysical propertiesLondon dispersion forcesMost of the articles in this issue provide opportunities for students to consider how understanding chemistry can help them make decisions in their personal lives. Consider asking students to read “Open for Discussion: Are Vitamin Supplements Necessary?” on page 4 to extend the information in “Got Vitamin D?” on pages 5-6. The infographic on page 19 provides more information to support the article “Drained: The Search for Long Lasting Batteries” on pages 10-12.You could ask students what batteries and pencils have in common (graphite), then ask them to elaborate on the physical properties of graphite that makes it appropriate for both uses.To help students engage with the text, ask students which article engaged them most and why, or what questions they still have about the articles. You might also ask them how information in the articles might affect their health and/or consumer choices. Also ask them if they have questions about some of the issues discussed in the articles.The Background Information in the ChemMatters Teachers Guide has suggestions for further research and activities.Got Vitamin D?Directions: As you read, complete the graphic organizer below to describe where we obtain vitamin D and why we need it.Vitamin DSources How our bones use itEffects of overdoseSummary: On the back of this paper, use information from the article to write a tweet (280 characters or less) about vitamin D.Cheesy Science!Directions: As you read the article, complete the graphic organizer below to compare the chemistry of how hard and soft cheeses are produced.Examples of hard cheeseSteps to produce hard cheesepHTemperatureWhat happens in this stepAdding bacteriaCreating curd (coagulation)Finishing cheeseExamples of soft cheeseSteps to produce soft cheesepHTemperatureWhat happens in this stepAdding bacteriaCreating curd (coagulation)Finishing cheeseSummary: On the back of this paper, write three new things you learned about making cheese that would like to share with a friend.Drained: The Search for Long Lasting BatteriesDirections: As you read the article, complete the graphic organizer below to describe the chemistry of batteries.Battery PartAnodeCathodeElectrolyteWhat it does/ What happensSingle use alkaline batteryLithium-ion rechargeable batteryFuture possibilities being researched Summary: On the back of this paper, list two ways to increase the battery life of current cell phone batteries, and why these methods work.Teens and DepressionDirections: As you read the article, complete the graphic organizer below to compare SSRis and MAOIs.SSRIsMAOIsExamplesHow they workSide Effects Summary: On the back of this paper, write a short email (2-3 sentences) to a friend explaining the chemistry of depression.The Write Stuff: The Fascinating Chemistry of PencilsDirections: As you read the article, complete the graphic organizer below to describe what you learned about the chemistry of all parts of pencils.Pencil partWhat it is made ofThe chemistry of how it worksPencil core (“lead”)Painted partMetal holding eraserEraserSummary: On the back of this paper, write a one-sentence summary (20 words or less) of the article. ................
