# Hon Chemistry 10-30-20 Chemical Formulas – Part 1

HON CHEMISTRY: Great start on writing and naming chemical formulas! What’d you think? Do-able? Absolutely!!

Today we concentrated on binary ionic compounds today with a short look at compounds with polyatomic ions. We’ll go kind of slow to begin with, but make sure to take time to practice, practice, practice, and learn it step by step. You’ll be as lost as ball in high weeds if you let yourself get behind!

# Chemistry 10-30-20 Graphing with Spreadsheets

CHEMISTRY: Today you are going to learn (or review) how to make graphs using data analysis software like Google Sheets or Excel by watching the video below at your own pace.

Here are the instructions for today, Friday. In class, you will follow along with the video instructions and make the same practice graph that I am making. This is due at the end of class. (You are going to be dreaming about graphs!!)

IMPORTANT Homework Update: A rough draft of the practice graph is due Tuesday class time. Graphing Exercise 2 is also due by class time on Tuesday. We will start on the Graphing 1 assignment next week.

You can do this assignment at school or at home with your own computer. If you use any device other than a PC or any graphing tool other than Excel or Google Sheets, you may need to modify the instructions to fit your device.

1. Watch one of the vodcasts below for a tutorial on how to make graphs in Excel or Google Sheets.
• My advice is to use a split screen view on the laptop with the video on one side and Excel open on the other side of your laptop screen. Watch the video and at the same time pause it as you follow along with the steps in Excel. Holler if you need me to show you how to do a split screen view. Or Google it! π
• The practice graph is due at the end of the period.2. When you begin working on the practice graph, pay very close attention to the instructions. Also, pay close attention to the sheet on How to Make a Best Fit (Scatter Plot) Line Graph in Excel 2010 – UPDATED to make sure you have all the parts of the graph covered.

3. If you need a sample set of data to play around with, click here: Sample Data for Graphing Practice

4. Google Sheets only: If you ever need to add subscript or superscripts to the axis labels in Google sheets, try copying and pasting whatever number you need from this set in to the axis title in Google sheets: β°ΒΉΒ²Β³β΄β΅βΆβ·βΈβΉββββββββββ

Now go forth and conquer graphs!!

# Physics 10-29-20 A Beginning Look at ZORBA

PHYSICS: Awesome job working with the Zorba problem – and early morning help session no less! Loved, loved, loved watching you brainstorming, collaborating, and applying information you’ve previously learned!!

Now…can you go and do the Zorba problem on your own?

# Chemistry 10-29-20 Fundamental Science Skills Graphing Activity

Quick – list 10 things you remember from the 8th grade about interpreting and reading graphs! Not to worry – today you’re going to begin reviewing those important concepts and techniques. Here is your assignment for today, Thursday:

IMPORTANT: Today’s assignment is one that you will have to complete at school. The program is on the school laptops and on the computers in the computer lab.

1. Find the “Fundamental Science Skills” program on your computer.
2. In the Graphing Skills section, click on “Graphing Data Points.” Read through and practice in each section VERY CAREFULLY!
3. After you have completed each review section, go to the exam and complete it.
• You must enter your name in the exact format you do when you title a lab – including the title of the activity.
• Click on “Check Your Answers.” When you have 100% accuracy, bring your lap top to me to check your Check Answers Results Sheet. If you are doing the assignment outside of our class period, print off your exam results sheet and bring it to me to check.
• IMPORTANT: Your answers and the format of it all must match exactly to receive credit. (Sometimes being exactly correct is extremely important!)
4. The Graphing Data Points assignment is due by the end of the class period today.
5. When you finish, next go to the Worksheet Tab and begin Graphing Exercises 2.

Holler if you have any questions!

# Physics 10-28-20 Newton’s 2nd Law

PHYSICS: So what changes motion? Here is our look at Newton’s 2nd law.

One of the most important things to remember – net forces produce acceleration. Now let’s see where you can take it!

# Physics 10-23-20 And Did the Hammock Crash?

PHYSICS: Great work today thinking through this one and also the “Wanda has a sign” problems! How you look at problems from the beginning can make a huge difference – huh?

A couple of things that work for me when doing equilibrium, etc., problems – first, draw them. Then go back through and separate resultants into components. If an object is in equilibrium, then there are no net forces – all the forces in the x direction balance – everything left equals everything right, and all the forces up equal all the forces down.

You’ve got all the ammo you need, now go forth and conquer!

Answers for the Equilibrants II worksheet are below:

1. Fn = 3430 N upward against feet
2. Fn1 = Fn2 = 1890 N upward on each foot
3. F forward = 4.59 N
4. T1 = T2 = 1760 N
5. T1 = 1360 N and T2 = 680. N

# Physics 10-22-20 Forces & Equilibrium

PHYSICS: So, how is the balance in your life? Here’s our discussion of net force, equilibrium, and equilibrants. Were you experiencing a little dΓ©jΓ  vu? Great job today!

# Chemistry 10-22-20 Chapter 1 Test Help Session

CHEMISTRY – Are you ready? God bless you as you study! Here’s the help session from this morning – good stuff!! (FYI – I didn’t put on the mic until about 24 seconds. Crazy morning!)

Make sure you aren’t just reading your book and notes. First, memorize the facts, then go back and make sure you can apply the concepts. Study examples, make your own examples, practice making questions. And don’t forget, if you are getting lost with everything you need to know, or if you’re not sure how to study, Chapter 1 Stuff to Know Sheet under the Test Info tab

Don’t forget the Chapter 1 Pre-test. Scroll down here on the web site for the web post from yesterday to find it. Also remember there are great review games that are in the Student Premium section of the online textbook. You can do this – I believe in you! I’m praying for you!!

# Chemistry Chapter 1 Pre-Test

CHEMISTRY: Here’s some GREAT practice for the test – a Chapter 1 Pre-Test. Fill in your answers below. When you are finished, be sure and click Submit and check to see which ones you missed.

UPDATE: This is the new Thursday night homework (and you can also work ahead). Use it to study for the test! It’s due by 8:00 AM Friday morning. Let’s see what you know! π
