Ionic compounds QUIZ- Tuesday , 3/28/17

Khan academy:  https://www.khanacademy.org/science/chemistry/atomic-structure-and-properties/names-and-formulas-of-ionic-compounds/v/naming-ions-and-ionic-compounds

Study.com:  http://study.com/academy/lesson/naming-ionic-compounds-simple-binary-transition-metal-polyatomic-ion-compounds.html

3/27/17  Today in class we turned in WS2, discussed ionic vs metallic solids using the example of aluminum (Al) and alumina (Al2O3).  Tomorrow is a quiz on ionic compounds- students will need to create formulas, name compounds, use transition metal rules, and know ALL of the polyatomic ions.

3/24/17  Today in class we will have Science Friday- the topic is Graphene.  You want to be able to discuss why graphene is interesting, why is it a conductive material (eventhough it is a non-metal), in a world where we have so many metallic elements why are we using carbon based conductors and what kind of applications it might have.

3/23/17  Today in class we reviewed polyatomic ions with KAHOOT!  We also had in class work time to complete WS 3 (Due today and WS 5 (Due Friday.  Students received WS 2- Due Monday...whew!  Tomorrow is science Friday- topic is graphene.  Be sure to research, print, annotate, and summarize your article for tomorrow.

3/22/17  Today in class we learned about ionic compounds that involve transition metals.  A great video that will help with this assignment and goes along with WS3 can be found at https://www.youtube.com/watch?v=Rq0A-AHdB74

Today in class we learned about ionic compounds that involve polyatomic ions.  A great video that will help with this can be found at https://www.youtube.com/watch?v=p9iQ5Qn42DM.  We also practiced creating ionic compound formulas using Kahoot!

We also received WS5.  WS3 is due tomorrow, WS 5 is due the next day.

3/21/17  Today in class we learned about ionic compounds.  A great video that will help with this assignment and goes along with WS3 can be found at https://www.youtube.com/watch?v=URc75hoKGLY

3/20/17  Today in class we examined digital models constructed using x-ray crystalographic imagery- essentially digital ball and stick models to discover patterns that differentiate ionic, molecular, and atomic solids. This should be completed as HW if you did not finish in class. Also, we turned in WS1.  Brassing a penny questions are due tomorrow.  

3/17  Today in class we made golden pennies.  We used electroplating to create a brass alloy on a copper surface.  Fun Day!  Reflection questions for Brassing a Penny are due Monday.  Also Unit 6 WS 1 is due Monday if you have not already turned t in.  Happy St Patty's Day!.

3/16  Today we took notes on metallic, covalent, ionic, and hydrogen bonds.  We then worked on WS1.  Students had about 30 minutes to work on WS1 in class.  If they did not finish, it became homework.  WS1 is due Monday.

3/15  Today in class we will model conductors and insulators using our generated data.

3/14  Today in class we did some sense making of the Van de Graaf phenomenom- just why is it that those pie pans flew off one at a time?

3/13  Today in class we watched the second half of the NOVA program, "Hunting the Elements"

3/10  Today in class we observed the Van de Graaf generator (VDG) in action- we placed aluminum pie pans on the VDG and observed that they fly of one at a time!  This is kind of awesome...

3/9  Today we tested conductivity.  Students collected data on the conductivity of more than 20 substances. Students then created a list of substances, grouped the substances based on a characteristic, and labelled that group.  After this as complete students Answered the following questions in their journal:

1.What similarities do good conductors share?  What are some differences?
2.What similarities do good insulators share?  What are some difference?
3.Provide a rationale regarding the conductivity of various solids, liquids and solutions.


3/8  Today in class we analyzed the data from the Sticky Tape Activity.  Students came to a consensus on the model of the atom we will use for class.  In addition we decided the mobile particle, the subatomic particle which moves between atoms, is the electron.  We looked at data and from the trends we concluded the following: There are 2 charges (positive (+) and Negative (-)). No homework. 

3/7  Today in class we used tape to investigate how our observations are linked to the molecular or atomic structure of substances in the Sticky Tape Activity. Students collect data on the interactions of top and bottom tap[e layer with various substances like foil, paper, balloons, wool and wood.  This data was shared with the whole class in an Excel spreadsheet.  No homework.

3/6  Today in class we watched the first 50 minutes of the NOVA program, "Hunting the Elements".  MS. Lin was at a teacher collaboratory meeting, there was a substitute. No homework.

3/3  Science Friday (topics differ by period)

3/2 Unit 5 Exam, Homework: Science Friday Tomorrow! Each period is doing a different topic.  Every student needs to research an on-topic article that contains scientific data. This article should be printed, annotated and summarized and brought to class Friday.  Summary should include a summary of the article, relate the article to chemistry, and identify a few questions that arose during the reading of the article.

3/1  SAT for juniors, work day for others... Unit 5 Exam tomorrow.  Your review is the key to test corrections.  Study and be prepared.

2/28  Today in class we worked a few sample problems then had a work period.  WS 3 and GB problems were turn in.Homework:  complete the Unit 5 review, test Thursday.

Science Friday Requirements:  

  • Each student researches to find a scientific article on the topic.  
  • The student then scans to ensure the article contains scientific data, if it does print the article.  
  • After printing, the student reads the article annotating as she reads.  To annotate means to mark up the paper, highlighting important ideas and using the margins to write notes, pose questions, or show reaction.  
  • Finally the student summarizes the article writing to answer these questions:  
  1. What was this article about?  Why is this article important?
  2. How does this article relate to chemistry?
  3. What questions or ideas did reading this article generate?  

Points Earned: 20 points possible each Science Friday

  • Article with scientific data (5pts)
  • Annotations(3-5 points)
  • Summary (3-5 points)
  • Verbal presentation (3-5 points)
  • Active listening (3-5 points)

A message from our librarian, Mrs, Ferbache-


As librarians (& teachers) we try to teach students to take a look at the information they encounter for accuracy & bias, especially what they read online. I ran across some interesting ideas about teaching students (and ourselves!) how to analyze what we read. I thought you might enjoy some of these articles/blogs –

“Teaching News Literacy? Check Your Own Bias, Says Librarian” -- http://www.slj.com/2017/02/industry-news/teaching-news-literacy-check-your-own-bias-says-librarian 

Within that article there are a couple of links. One of them took me to a blog post by Tasha Bergson-Michelson, a librarian at the Castilleja School in Palo Alto, CA –

“Did Media Literacy Backfire?” -- https://points.datasociety.net/did-media-literacy-backfire-7418c084d88d#.awcbmpuqt – which notes that “too many students I met were being told that Wikipedia was untrustworthy and were, instead, being encouraged to do research. As a result, the message that many had taken home was to turn to Google and use whatever came up first. They heard that Google was trustworthy and Wikipedia was not.” Read how the author thinks the internet and our “culture of doubt” is polarizing this country.

Another link took me here –

“Reading News across the Political Spectrum” -- http://aislnews.org/?p=4851 – which includes the statement that students are unable – “to distinguish between what felt good and what was good quality. Generally falling along a political spectrum, articles that aligned with what students already believed earned a rating of “reliable” … and the other sources were all considered equally foreign and indigestible.”  And the author teaches students that “research is not about starting with something you believe to be true and cherry-picking evidence to prove it. Rather, we look at a range of rigorously supported viewpoints and draw evidence-based conclusions.” 

And yet another link led me here -

“Why America is Self-Segregating” -- https://points.datasociety.net/why-america-is-self-segregating-d881a39273ab#.wl351lsif – while not strictly about accuracy & bias in news and on the internet, the points made here are related to how we determine what we see as “fake news” or “accurate” and how we look for “safe spaces” and “culture fit” in our lives and our “news”.
