Science Exams First Thing Thursday – December 13

Awesome job with review today! God bless you as you study for your chemistry, honors chemistry, and physics exams! How are you studying? Best advice? Practice, practice, PRACTICE! Be active in studying – don’t just read over the material. Review games on the online textbook, reworking old homework problems, re-working those flash cards you’ve made – all good. Watching vodcasts of old lectures might not hurt either!

Chemistry Exam Help Session Thursday morning, 7:00 A.M.

IMPORTANT – Bring your exam review packet (and textbook, if you checked one out) to the chemistry room before you go to your exam room!

Here are the room assignments for Thursday’s exam:

Chemistry 1 Rm. 302 (Mr. Henton’s room)
Chemistry 2 Rm. 303 (Mrs. Tapp’s room)
Chemistry 3 Rm. 304 (Coach Henderson’s room)
Chemistry 4 Rm. 307 (Mrs. Berryhill’s room)
Hon Chemistry 6 Rm. 301 (Ms. DeFrehn’s room)
Hon Physics Rm. 300 (Coach Sheron’s room)

Don’t forget to bring your completed exam review packets when you come on Thursday. I’m praying for you!!

Exam Fuel

Come by our classroom Thursday morning before the exam for a cup of hot chocolate or cider and little white donuts!(7:00 – 8:05ish A.M.)

You’ll need to bring your exam review packet to the classroom BEFORE your exam, so while you’re at it, grab some exam fuel!

Also, don’t forget the Chemistry help session Thursday morning, 7:00 A.M. Come for exam fuel for the mind and body!!

Chemistry 12-5-18 Chapter 7 Test Overview

CHEMISTRY: God bless you as you study! Here’s our overview of the test from today. Below that is the Help Session from this morning. Also, did you find the Chapter 7 Stuff to Know sheet? Be sure and use it as a road map for your studying. I know it seems like a lot, but you can do it!

First priority – make sure that you have memorized EVERYTHING. Then, practice!!! Go to and make sure you can write and name chemical formulas. Practice, practice, practice!!! Then start practicing the different kinds of problems – do at least three of each one of them. And also try those on That’s always some good practice. And don’t forget about polymers!

I’ll be praying for you! You can do it!!

Wednesday Morning Help Session

Chemistry 12-4-18 Polymers

CHEMISTRY: We finally finished the chapter! Did you realize molecules could be that large? And so many of them. But don’t you think polymers are cool? Here’s the lecture for Tuesday.

Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe? Hmmmmm…

Chemistry 12-3-18 Molecular Formulas

CHEMISTRY: Hey guys! Awesome job with empirical formulas, and now you’ve conquered writing molecular formulas! Here’s the lecture from Monday. It’s just like writing empirical formulas but with a twist at the end!

We are getting very close to the end of the chapter! Homework for tomorrow night (Tuesday) will be the online practice test in PowerSchool learning. Make sure you are logged in as you, and then go to the calendar and you should see it there. It’s also on the Chemistry page – holler if you can’t find it.

Have you started preparing for the test? It will be over ALL of chapter – plus the small bit from chapter 3. Be sure and checked out the Stuff to Know sheet for all of chapter 7 on Edline!

By the way, if you’d like some practice or if you have questions, help session Wednesday morning, 7:20ish A.M.!

Chemistry 11-30-18 Empirical Formulas

CHEMISTRY: So, would you like to be Greg on CSI? Great start on empirical formulas today!

The hardest part is that it’s not a set formula for you to plug and play, but if you’ll keep in mind that you’re really just looking for subscripts which are just moles, you’ll be able to think it through. Percent to mass, mass to moles, moles to smallest whole number ratio.

Monday we’ll talk about a little step you get to add at the end. 🙂

Chemistry 11-29-18 Percent Composition

CHEMISTRY: Great job with the different ways to look at percent composition! A little bit different lab procedure, huh?!! If you need to make it up, this lab is answered only on notebook paper – be careful to show correct data and calculations!

BTW – I think you’ll find that percent composition problems are really easy to catch on to. Make sure, though, you can write chemical formulas (I won’t give them to you!) and that you’ve memorized the formulas for acids and those chemical names for common substances so that you’ll have something to find the percent composition of!

Chemistry 11-26-18 Formula Mass & Molar Mass & Molecules

CHEMISTRY: So the little mole turns out to be a pretty big deal – and a very handy tool!!

Great job today! Here’s discussion on formula mass and molar mass, and then using molar mass and Avogadro’s number as a conversion factor. You’ve got a couple of great tools – so now think through the problems and go forth and conquer!! Be sure and practice them so you don’t forget!

Chemistry 11-16-18 Moles, Mass, Atoms & Avogadro

CHEMISTRY: So… how big a bucket do you think we’d need to hold a mole of frogs? 🙂

Nope, not the furry brown creature that burrows underground, it’s a whole different thing! Here’s the lecture from Friday on moles, mass, and Avogadro’s number. I still say he has a cool name… 🙂

Chemistry Assignment for Monday, November 12

CHEMISTRY: Happy Monday! Here’s your assignment for Monday. Read the instructions below very carefully!! (If you have done this assignment already, do it again – but it’s different! The practice will be very helpful for you!!)

Today you’ll practice again on, but instructions for today are different. Today you will need to write the question, and then beside it, the correct answer, and you must turn in your work on notebook paper – but you only have to do 15 compounds correctly from each section. When you get 15 done correctly in each section, you may stop and go on to the next section. Skip a line between each compound. You may write on the back.

Go to, go to Chemistry, click on NEW Review & do the following. On your notebook paper, write the question, and then beside it, the correct answer. BE SURE AND CHECK YOUR ANSWER. This assignment will be graded for accuracy.

Label each new section, and skip a line between each question.
1)  Unit 3: Binary Ionic Compound Formulas (Don’t forget that you DO have to put charges for the ions in the formulas when you show your work!)
2)  Unit 3: Ionic Compounds Involving Polyatomic Ions (Don’t forget that you DO have to put charges for the ions in the formulas when you show your work!)
3)  Unit 3: Binary Covalent Nomenclature (Don’t forget that you DO NOT put charges for the ions in the formulas when you show your work. Prefixes are the subscripts!)

You must have 15 correct answers from each section before you can turn in your work. The assignment is due at the end of the period. If you finish early, use your time to practice other things for the Ch 7 Pre-test quiz.
