NOTES: ELECTRON CONFIGURATION

Students, here is the Power Point for the Unit 2 notes on electron configuration, orbitals, models of the atom, and rules for electrons:



Students should use this along with the previous section of Notes to complete the Study Guide for next Thursday's test (10/18), and along the way make sure that everything in the Study Guide does, in fact, appear in their notes.

HONORS: THE PERIODIC TABLE

HONORS STUDENTS:  Here are the Power Point Notes on the Periodic Table given in 1st period.  

Inside you will find information about the structure of the periodic table, how to read it, how to calculate molar masses, isotopes and ions, ionic and covalent bonds.   This needs to be completed in your Composition Book this week, as we are moving on to other material.



VIDEO: FLAME TEST

If students were absent on Monday, Oct. 21st, they did not get to see the actual lab where we performed a 'flame test' on various ionic compounds.   

Here is a video that shows much the same sort of observations students made on Monday.   Unfortunately, it is not practical to 'make up' this particular lab. Watch the video, students, and compare it with observations that students who attended were able to make in order to understand the material:

REGULARS: SATURDAY SCHOOL

Is it an opportunity or a punishment?

That's up to you, students.

Some of the students in my Regular Chemistry classes have received a YELLOW CARD which assigns them to Saturday School, where they will work on a package of remedial work.

Saturday School for Regulars will occur on Sat., Oct. 26th.

It is the responsibility of students to have parents contact the instructor to make an alternative arrangement in the event of a conflict.

VIDEO: COVALENT AND IONIC COMPOUNDS

Both Honors and Regulars are doing activities in October that require them to distinguish between covalent and ionic bonding.  This video from Paul Anderson is a master teacher's original way of teaching how to use a periodic trend (electronegativity) and the octet rule to determine whether a compound is ionic, polar covalent or non-polar covalent.



VIDEO: THE BUNSEN BURNER

VERY IMPORTANT:  On Monday, Oct. 21st, all of Mr. Hatfield's classes (Honors AND Regulars) will be doing an activity that involves gas.  Students are expected to know how to do this safely!

Mr. Hatfield has made a video to demonstrate the correct way to use the Bunsen burner.  Make sure you review this before you come to class on Monday, as we will be using the Bunsen burners in class to perform the 'Flame Test Lab'.


HONORS: STOICHIOMETRY

Honors Students, I am making this Paul Andersen video available through the class blog.   Please watch as many times as you need:

HONORS: THE CONVERSION EXPERIENCE, PART 2



Honors Students:

This is the SECOND part of 'The Conversion Experience', which are the Notes that form the basis of the Study Guide of the same name.


The first part covered the concept of the mole and molar conversion problems, which used fractional setups with cancellations.

This second part adds the concept of the balanced equations used to describe chemical reactions, and combines those equations with molar conversion setups to make real-world measurements of predictions of actual reactions.

The Honors Syllabus for Period 1 is shown below, in blue:



Periods 2-5 are found below, in white:



These two syllabi are significantly different from one another.  Just remember, students:  HONORS syllabi will always be blue, while regular Chemistry syllabi will be white.


"TURNITIN.COM" : HOW TO JOIN A CLASS

Beginning this month, students will submit electronic documents to the online resource 'TURNITIN.COM'.    This web site promotes student integrity by comparing student submissions with the entire Internet.  Perhaps more helpfully, it also provides a way for your instructor to GRADE your electronic document on-line, and send you feedback on how to improve your work on-line.

Mr. Hatfield has already created an account for all of his students using that student's district e-mail, and enrolled students in an on-line class.   Mr. Hatfield sent an e-mail to each of his students notifying them of their account's existence, and students will be expected to confirm they have read the email by sending an email reply.

The next step, for all students, is that students must be able to log on to their account.   For this, they will require a class ID and class enrollment key, which will be provided by Mr. Hatfield.

HOW TO "C.O.P.E." WITH MR. HATFIELD'S TESTS

On Friday,  September 6th, Mr. Hatfield's students took their first test in Chemistry.  The first test can be thought of as a 'lesson' on what to do, and what not to do.  Until students see the test for themselves, and know what it is like, it's difficult to prepare for.  

So, many students will be disappointed and discouraged by their first exam, when it is returned in class TODAY.  But know this: if you learn from the experience, you will improve, and you will even get opportunities to improve your original grade.    

Students who earn a percentage score higher than that earned on the first test can not only expect to earn a higher grade, but they are eligible for grade change on their previous test.

To achieve that, students need to consider the following, using the anagram 'COPE'.

C....(ontent)

Students need to know what's on the test. 

To make sure that students know what content will be covered on the exam, they need to obtain and complete a copy of the Study Guide or Guides, which become available a week before the test.   At the same approximate time, Mr. Hatfield will make the notes and practice questions available on the class blog. The sooner the students develop the habit of comparing their Composition Book with these materials, the sooner they will improve!

O....(rganization)

Students need to plan their time. 

Students should consider forming Study Groups with fellow students, perhaps after school on the day before the exam. They earn points by attending, and get valuable feedback about what is likely to be covered.  Students need to consider using time on lunch or after-school on the day of their exam as needed to complete their test. Plan ahead, students!

P...(reparation)

Students need to provide evidence that they have prepared for the test. 

One way to do this is to attend Study Hall during lunch, before the next test. Another, powerful way is to make sure that they bring their COMPLETED NOTES  to class on the day of the exam, inside their Lab Composition Book. To aid Students in completing their Notes, Mr. Hatfield makes them available on-line through this blog and gives a Study Guide for Students to complete to demonstrate that they have the Notes, and know what to do with them.  Bring evidence that you have prepared for the test, students, and you will be rewarded!

E...(ffort)

Students need to finish what they start

There is nothing more important than giving our best effort, all of the time. On an exam day, a good effort means that students attempt everything, even if that means they need to come back at lunch or after school. Show a work ethic, students, and you will not only do better on the test....you will do better in every aspect of your life.

PARENTS, ENCOURAGE YOUR STUDENT TO USE THESE STRATEGIES TO EXCEL!


One way to improve O(rganization) and P(reparation)  is to use the SYLLABUS for each Unit.   With that in mind, here is the SYLLABUS (the schedule of major events) for Unit 2:

NOTES FOR UNIT TEST 1: SCIENTIFIC METHOD AND CHEMISTRY


Students should use the Power Point below to complete their notes inside their Composition Book, as needed.  

Students ARE allowed to use their Composition Book on the day of their test, so . . . be prepared, students!



The topics of the notes include the relation of chemistry to mathematics and other sciences, what makes chemistry distinctive in terms of its content and practice, the nature of science, scientific method ("O.H.E.C.K."), evaluating hypotheses, experimental design, significant figures and scientific notation.

Students should download the Power Point Notes to make sure that their notes are complete, as from time to time their composition books containing their notes will be inspected and graded.

You can find that set of notes HERE.http://www.mediafire.com/file/adb9pexdajs18kw/Scientific_Method_and_Chemistry.ppt/file

VIDEO: "COSMIC VOYAGE"

Chemistry students will be viewing a 36-minute IMAX video in class beginning on Tuesday, September 3rd, and completing a worksheet based on part of the video. The film, 'Cosmic Voyage', was made in 1996 for the Smithsonian Institute and was clearly inspired by a classic science education film called 'Powers of Ten', originally produced in 1977 by the husband-and-wife team of Rae and Charles Eames.

'Cosmic Voyage' approaches the idea of using the metric system, which is based on powers of ten, to explore the question: "What is really large, and really small?" The film first zooms out from an acrobat's ring in St. Mark's Square in Venice, the place where Galileo first trained his telescope on the heavens.


Through 23 powers of ten, we leave first the Earth, then our solar system, then the Milky Way Galaxy behind, until we reach the limit of modern astronomy, where we can see images from about 13 billion years past.


Reversing course, the video then zooms in on drop of water in the Dutch town of Delft, where Antonie Van Leuuwenhoek first trained his early microscope to discover the hidden world of microbes.



As we zoom in on a paramecium, we penetrate its cell nucleus, then zoom in on a molecule of DNA.


Within that molecule is a carbon atom, and the world within that atom is mostly empty space! Within the atom, the atomic nucleus contains virtually all of an atom's mass, made of particles called protons and neutrons. These, in turn, are formed from even smaller particles called quarks.

The film continues with a discussion of the search for a fundamental theory in physics through the use of particle accelerators like Fermilab, along with an overview of the likely "recent" events that led to our sun, our solar system, the Earth and life itself.

Here, presented on YouTube, is the entire film, if you wish to review the material or share it with others. As the narrator (Morgan Freeman) intones, 'we are all travelers on a voyage of discovery!'

THE SYLLABUS IS MADE FOR STUDENTS . . .AND NOT THE OTHER WAY AROUND




What do I mean by that, students?   Simply this:  that the syllabi that I provide in each instructional unit are intended to help YOU manage YOUR time.   The dates shown in the syllabus, and the due dates, are meant to be suggestive, not inflexible.

Because this is true, students should not become alarmed if they sometimes are unable to hand in an item precisely when it is shown on the syllabus.  Students should not be surprised if sometimes an item is given out at a later date than shown.  

The important thing is that students should try to complete all the items before the end of the unit.
Once the unit is over, there IS a grace period of one week to hand in any items not completed.  After that date, they will not be accepted.

Monday, August 19, 2019

UNIT 1 SYLLABI FOR HONORS, REGULAR CHEMISTRY

The Honors Syllabus for Period 1 is shown below, in blue:


Periods 2-5 are found below, in white:


The two syllabi differ very little in the beginning of the year due to the logistical requirements of setting up different courses, but will diverge in sequence and in assessments during the semester.  Just remember, students:  HONORS syllabi will always be blue, while regular Chemistry syllabi will be white.

EMAILS AND DOCUMENTS

At this point, some students are concerned.  While most students have already demonstrated they can send their instructor an email, they may not be clear with how to handle the electronic documents they will be required to create in this course.  

They may be unsure what software to use to create their document, or they may be unclear about how they should save their documents, or have trouble figuring out how to attach those documents to email.  THIS POST ATTEMPTS TO ADDRESS ALL OF THESE PROBLEMS!

Mr. Hatfield recommends that his students use the program Microsoft Word to create electronic documents.   This program is part of a group of programs sometimes called 'Microsoft Office', but more commonly-called Office 365.

Not only is Office 365 available on all FUSD-supplied computers, FUSD students can get up to five FREE copies for their home computer or mobile device.   However, some students are either not aware of this, or they do not know where to go to obtain their free software package.

So let's show you "where to go".   First, go to a search engine and enter this character string:

portal.office.com

This may take you right to Office 365.  But sometimes, instead, it takes you to your student account with OneDrive, and you'll see this screen:




If that happens, look in the upper corner, where it says 'Office 365', and click on that.   When you do that, you should definitely arrive at THIS screen:




Now, a key point about all of this, is that once you have a word processing program on your home computer, you need to be able to save and email the documents you create.   The GREAT advantage of electronic documents is that they can be easily reedited in any way you want without either destroying the original or completely re-doing the assignment!   So, on your home computer, dedicate a folder where you store your classwork, so you can easily find previous work when you need to edit it, or attach it to an email.

And as far as emailing goes....look for one of these:



OK, actually not a literal paper clip.  But virtually all email programs use a "paper clip" icon as a means of attaching documents to an email.   I'm going to share some screen shots of some of the most popular email services below to make that point.....



So, if you've created your document....and you know where it's at on the computer you're using...look for the word 'attach' or a 'paperclip' icon in your email, and click on that item.   A window will open that will allow you to select the location on your computer where you've saved your document.   Find your document, select it, and it should be attached to your email...

"BUT WHAT IF I DON'T HAVE EMAIL?"


Ah, but every FUSD student has free email through the district.

You just have to know how to access your email account.   This post tells you how to do that.







So...all of Mr. Hatfield student's should know:

  • how to get FREE copies of 'Office 365'
  • how to store and attach electronic documents
  • how to access their FREE email through the district
THUS....there should be NO EXCUSES.   Students who don't complete their 'Hidden Figures' assignment or other future assignments that might require an electronic document aren't really following the Course Contract, and thus might be assigned Saturday School.

WELCOME TO CHEMISTRY!

Welcome to the 2019-20 school year, students! We spent most of the first week getting to know each other and learning some of the basics of classroom procedure.  

Most of the next 175 days of instruction will be devoted to reviewing the fundamentals of Chemistry.

A major focus of interest for chemists is pursuing all the different ways that matter and energy can be arranged.  Much of that knowledge can not be predicted in advance by any theory, but instead can only be determined by experimental investigation.   For this reason, Chemistry is an 'in-between science' focused tightly on the design, performance and analysis of experiments.  This emphasis on the experiment requires chemists to use math constantly:  in a sense, Chemistry is a math course with scientific application.

To help students understand the importance of math to science, and how mastering mathematics opens doors for tackling all kinds of problems, students will be asked to consider the true story of the West End Computer Section in U.S. space program, as shown in the film 'Hidden Figures.'   They will see how an unappreciated group of human 'computers' used their abilities to approach scientific and social problems, and how they did their part to achieve great things.

Here is a brief trailer for the film.  It shows an outline of the film's story:



Also, here is a short feature about the making of the film. In this feature, you will learn how author Margo Lee Shetterly, who wrote the book on which the film was based, grew up learning about the 'human computers' at West End, and how she became convinced that she needed to tell the story of women like Katherine Johnson and Dorothy Vaughn:

THE PARTICLE ADVENTURE

What's that, you say?   You're one of Mr. Hatfield's students, and the final is getting close, and you're not happy with your grade?   Are you suddenly aware that maybe, just maybe, you should've spent less time playing on your cell phone and more time actually completing work outside of class, and you wish, fervently, that there was some 'EXTRA CREDIT' to help raise your grade?

('sad trombone' sound)

SUPPOSE Mr. Hatfield not only offered an 'EXTRA CREDIT' assignment, and allowed you to submit it up to the last day of school, AND made the assignment based on 'playing with your cell phone'?  Would THAT help?

Here ya go, kiddlies:


Indeed!  Students will receive a packet today based on the charming web site 'ParticleAdventure.org',
all about quarks and other strange particles which are more fundamental than the protons and neutrons we've spend much of the year dealing with.   You can get a copy from Mr. Hatfield!  What do you have to lose?

POWER POINT NOTES: NUCLEAR CHEMISTRY

Students:

This is the FINAL set of Notes for the Spring semester!   The end is near, congratulations!

Your FINAL will be based on these notes, the (current) Chapter 25, and material from previously-taught chapters (17-24).




You can click on the image above or THIS LINK to download the notes.  

THERE IS ALSO A STUDY GUIDE, GIVEN IN CLASS, BASED ON THESE NOTES.  

If, for any reason, you were to lose that Study Guide before your Final, you can download that Study Guide as a PDF file,  HERE:

FINISHING OUR YEAR STRONG! (FINAL SYLLABUS)

Students:

Mr. Hatfield wants to remind all of you that our Unit on Organic Chemistry (Unit 8) is coming to an end on Tuesday, when students will take their Unit 8 exam.  The notes for that Test have been previously shared on a blog post.

HERE IS YOUR FINAL SYLLABUS, FOR UNIT 9:



Beginning on the very next day (Wednesday, May 14th), students will embark on their final Unit of the year, on Nuclear Chemistry----and thus 'the clock will be ticking' on any unfinished work from Unit 8.  This might include:

  • (2) Handouts, given in class, totaling 40 points on naming and drawing hydrocarbons and functional groups.  These will be past due on Tuesday.

  • (3) Labs, totaling 60 points, on modeling hydrocarbons, assembling esters and the polymerization of 'slime'.   Students will be expected to hand in their Comp books in class on Wednesday.

WE MUST GO ON AND FINISH THE YEAR STRONG.   The purpose of this post is to impress upon students the importance of completing their Unit 8 work on time, so that they can earn an average to above-average grade and not have to repeat Chemistry.

POWER POINT: CARBON THE SHAPE OF LIFE

Students:

Unit 8 (Organic Chemistry) ends with a Unit Test on Wednesday, May 16th!




To help students prepare, please find the Power Point Notes HERE, along with a PDF of the Study Guide based on those notes HERE.

Students should also have a copy of the Organic Compounds Guide (three-hole punched) as part of their materials for Tuesday's Test.

ORGANIC CHEMISTRY VIDEOS

Previously, we talked about the difference between organic (based on carbon) and inorganic (based on some other element) molecules.   Life, of course, is based on organic molecules.

There are four major classes of carbon-based compounds used by living things:   carbohydrates, lipids, proteins and nucleic acids.

Each of these compounds is made of individual 'building blocks' called MONOMERS.   The monomers are linked together with covalent bonds to make large chains called POLYMERS, and the process of making polymers is referred to as POLYMERIZATION.

Here's a video from Bozeman Science, with animations, that gives some nice background on monomers and polymers:




Carbohydrates are carbon-based macromolecules based on C, H and O.  They are polar and readily dissolve in water.

A simple sugar by itself, like glucose, is termed a monosaccharide, and serves as a 'building block' (monomer) to build a larger chain of many molecules called a polymer. In the case of carbohydrates, the polymer made from many monosaccharides linked together by dehydration reactions is called a polysaccharide.

Examples of polysaccharides made of glucose include cellulose, glycogen and starch.   Each of these glucose polymers are biologically important. 




 Finally, here's yet another video by AP Chemistry teacher Paul Andersen, this on the class of macromolecules called PROTEINS.   



 PROTEINS often are used to build extremely useful and specific molecules called ENZYMES:

VIDEO: "NAMING COMPOUNDS"

In this handy video, Paul Anderson reviews the basic rules for ionic and covalent bonding.  Students should compare this video with their 'Nomenclature Review' handout, as well as the (ionic) version of the periodic table on the back of their Unit 8 syllabus.


SYLLABUS, UNIT 8

Students, here is the Unit 8 syllabus that covers the nomenclature and properties of ionic, covalent and (especially) organic molecules:

NOTES: ACIDS, BASES, SALTS

Mr.Hatfield's Chemistry students have completed their Notes on material from Chapter 19.   They can download a copy of the Power Point containing those Notes HERE:


Students received a Study Guide based upon this section of Notes in Friday's class, to help prepare for their Unit 7 test on Wednesday, April 3rd.

VIDEO: 'REDOX' REACTIONS

Tyler DeWitt has made a very handy, easy-to-understand video that uses the formation of an ionic compound (NaCl, sodium chloride) to illustrate the logic of oxidation-reduction reactions, sometimes called 'redox' reactions, as described in Chapter 20.

Tyler not only gives an example of oxidation numbers (20.2), but he also shows how to to use these numbers to describe 'half-reactions' (20.3)

While there is no worksheet based upon this video, this is highly-similar to how students will be introduced to these concepts in Lecture, and is worth repeated viewings:

VIDEO: ACID-BASE EQUILIBRIUM

Students were shown this video in Friday's class.   Paul Andersen demonstrates the centrality of water to most acid-base chemistry, and explains how to calculate equilibrium constants for acids (Ka) and bases (Kb), and how to express those as pKa's or pKb's:


Friday, March 8, 2019

POWER POINT: CHEMICAL KINETICS



Students, here are the Power Point Notes on Chemical Kinetics, which covers the concept of equilibrium and the rates of reaction.


The Study Guide will be made available in class on Monday, March 11th.  If you need to get another copy, you can download a PDF version of the Study Guide HERE.

UNIT 6 is now over, and all Unit 6 work is PAST DUE, and will NOT be accepted after Friday,  March 15 (THE IDES OF MARCH) 



VIDEO: EQUILIBRIUM

In this video, Paul Anderson does a great job of providing a demonstration that suggests how chemical systems reach equilibrium.




Mr. Anderson also models how to equilibrium setups and solve for the value of the equilibrium constant, 'K'.  Students were given a worksheet based on this video in Friday's class, along with a set of problems in which they will practice setting up equilibrium expressions.

This is a short topic, and the notes on Chemical Kinetics were also finished.  Both items should be treated as homework, and completed as soon as possible.


Friday, March 1, 2019

Students:

Here are the Power Point Notes for Unit 6:  Thermochemistry.  




In this you will find discussions of phase changes (again!),  heat transfer, the 1st and 2nd Laws of Thermodynamics, and problems to calculate energy (q) , specific heats and enthalpies of reaction:

POWER POINT: ACIDS, BASES and SALTS

Mr.Hatfield's Chemistry students have completed their Notes on material from Chapter 19.   They can download a copy of the Power Point containing those Notes HERE:


Students will receive a Study Guide based upon this section of Notes in Friday's class, following their 'Electrochemistry Lab', and should use their prepared and studied Notes to attempt Wednesday's Unit Test. 

Wednesday, February 20, 2019

The following video by Paul Anderson was introduced in class on Wednesday, Feb. 20th .   It helpfully reviews some of the information already given in lecture regarding heat and the enthalpy of reactions. It also features a very handy, step-by-step demonstration of how to apply Hess's Law (a SUBTLE and advanced topic) to calculate enthalpies.




Students have an assignment based on that video, which is available HERE as a PDF file.

VIDEO: TEMPERATURE

As we begin our notes on the 'Kinetic Theory of Gases', it is important to realize that the random, dynamic motion of a very large set of tiny (sub-MICROSCOPIC) particles produces the phenomena we can observe at our own, relatively large (MACROSCOPIC) scale, like pressure and temperature.

Paul Anderson demonstrates this in the following video.  Students will receive an accompanying worksheet based upon it!

SPRING 2019: NEW UNIT 5 SYLLABUS

WELCOME BACK!

Students in Mr. Hatfield's Chemistry classes will be spending much of the first week of the Spring 2019 semester  completing handouts which review math routines taught and rehearsed in the Fall semester.  

On ATLAS, these assignments will display as four separate classwork assignments: Molar Mass, Two-Step Problems, Three-Step Problems and Stoichiometry 1.   Each is worth 20 points, but they are shown on the Syllabus below as a single (80-point) assignment:


Students should've also begun answering the Section Assessment Questions from Chapter 13, and beginning on Tuesday of the second week, begun to absorb new material on kinetic molecular theory and gas laws.
