VIDEO: ENTHALPY OF REACTIONS

The following video was shared in class on Thursday, Feb. 17th.   

This video builds on material introduced by your instructor, Mr. Hatfield, during lecture on Wednesday, Feb. 16th.

In the video, Paul Anderson 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.  Copies of this Assignment were made available in class to complete in class that day.

VIDEO: TEMPERATURE

Students:  Here is the 'Temperature' video by Paul Anderson, as shown in class.  Make sure you use colored pencils to complete the graph on pg. 3 of the handout based on the video.

POWER POINT: THERMOCHEMISTRY (1st 15 SLIDES)

Students:

Here are the first 15 Power Point slides from Mr. Hatfield's Thermochemistry Notes.   Use these to 'catch up' on completing the first two pages of the Study Guide on Thermochemistry.  Click HERE or on the image to download these slides.

WELCOME BACK! MOVING FORWARD . . .

Students:  Welcome back from Winter Break!   

Of course, it would have  been better if you had received this message on the first day of instruction.  I will be discussing the professional and personal circumstances that have kept me from being with you for the last two months, and reflecting on what would be the best way to support you for the rest of the year.  In the meantime, since we haven't connected until now, I hope you had an opportunity to "recharge your batteries", and reconnect with family and friends during the Break.

Now, coming back to school, we have yet another outbreak in our community to deal with as well, on top of the disruption to our class.  I know it hasn't been easy.

But, as the saying goes, the future is where we are going to spend the rest of our lives, and to know how to deal with the future, we will need to assess what students have learned in Chemistry in the last two months.

POWER POINT NOTES: ELECTRON CONFIGURATION 2021

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 to complete the Study Guide for next Tuesday's test (10/26), and along the way make sure that everything in the Study Guide does, in fact, appear in their notes inside their Composition Book.

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

 

On Tuesday,  September 28th, Mr. Hatfield's students began taking their first Unit 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. 

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!

VIDEO: FIREWORKS!

Students who were in Mr. Hatfield's classes on Tuesday, Oct. 5th, watched a PBS video entitled 'Fireworks!'  Students who need to watch it again, or who were not present on Tuesday, will find the video embedded below in this post.

The worksheet for this video can be obtained HERE.

Students should pay careful attention to TWO topics:

1) IONIC COMPOUNDS, which are described in Section 6.1 (pg. 158-163)

2)  ELECTRON CONFIGURATION (Section 4.4, pg. 124-127)
