Recording of 4/24 MS Chemistry Class - Fire part 2

Hi folks,

Today we got a bit deeper into the concept of combustion with a bunch of great demonstrations showing what the term "fuel" means when it comes to fire.  If you missed the class, be sure to check out the recording.  It's a lot of fun!

Recording of 4/18 MS Chem

Hi folks,

Here's the recording of this Friday's class.  Since we are at home, I'm taking advantage of this by doing my Combustion chemistry block.  Combustion means fire so we did quite a few experiments showing the chemistry of fire.  (Needless to say, I can't do this at Hope Church so that's one good thing about this "stay at home" stuff.)

There's a lot of fun demonstrations here so be sure to take a look.  Also, if you try any of these at home you MUST get your mom or dad involved.  Fire can be dangerous.

Also, here's a very nice little video of tea bag rockets.  I tried to do this in class but I never have good luck at this.  

Have a good week everyone!

Science Online Class information

Hi folks,

I'm still trying to tweak all this technology so that everyone can have the best easiest safest experience possible so here's a couple of new updates.

1.  I'm going to try posting the links to class to the Canvas site.  I'm going to post these as announcements so they should be right there when you log in.  Several folks have had their emails delayed for some reason and so they haven't been getting the emails on time.  I'm hoping this fixes that problem.  I will probably continue to send the links to class in emails as well.

2.  I'm going to start locking the classroom after about 5 minutes or so of class.  There are quite a few shenanigans going on out there with Zoom so I feel I need to lock down the classroom.  I've tried using the password option but there appears to be no way that I can see to keep someone in class from inviting their friends and sharing the password.  So, if you are late to class PLEASE TEXT ME! (919) 907-3217  I will try to keep my phone handy so that I can let you in.  

Best,

Jim Mueller

Bored? Try this chemistry game.

Hi folks,

This is sort of silly but it's fun too.  It's a chemistry game from the American Chemistry Society.  Give it a shot.

Information regarding tomorrow's online MS Chemistry class

Hi all,

I hope everyone is safe and well.  

So here's the deal, when you get a chance, go to zoom.us and sign up for a free account.  You can use your Google account or Facebook account if you wish.  When you sign up you'll be prompted to download a "Zoom App" for the computer (or the phone for that matter).   Once you have that you will be ready to go.

You will want to do this before class time tomorrow to make sure you're all set.

About 15 minutes or so before class I'll send a link that will take you directly to the class.

There's no need to have your camera on so please feel free to keep those turned off. 

Looking forward to "seeing" everyone tomorrow at the usual 10:00 time.

Best,

Jim Mueller

3/6 MS Chemistry Update and homework due 3/20

Hi folks,

First off, NO CLASS next week.  It's our Spring break so there will be no class next week.

Today we had a great time with our end of the trimester review.   We did a game show where the students created and answered the questions.  I was really impressed with the questions and even more impressed with their answers!  We had a lot of fun and it made for a great overview of the year.

For homework next week….NONE!!! Since there wasn't any new material this week there's really nothing new to work on and according to your quiz scores, you are all doing a great job keeping up with the material so there's no need for a review assignment.  Have a great break you've earned it!

Bring old stuff to Chemistry Class today

Hi folks,

Be sure to bring your old notes, quizzes, homework etc. to class today.  You may find they come in handy……. :)

See you all soon!

2/28 MS Chemistry class and homework due 3/6

Hi folks,

Today we continued our discussion on states of matter by discussing why matter takes the different states that it does and getting a little more specific into what a solid is.   As part of our discussion of solids, we defined the terms, compression and tension.   In order to spend some time with this concept we did a challenge where students had to create a bridge out of popsicle sticks that had one end attached to the table and the other end had to go as far away from the table without touching the ground (See "The Bridge to Nowhere" in the .pdf for more information).   The students could quickly see how tension and compression were quite difficult to overcome.

By the way, I apologize but I didn't get a recording this week.  However, almost all the content in today's lecture can be found in the enclosed .pdf. 

For homework this week read the enclosed .pdf and answer all the questions at the end of the chapter.

ALSO answer the following questions based on today's lecture.

(If you missed today's lecture, feel free to look at the answers for the first 4 questions here.)

1.  What does temperature measure?

2.  As temperature goes up do molecules go faster or slower?

3.  Which state of matter tends to have the highest energy?

4.  Which state of matter tends to have the lowest energy?

5. What is the major difference between solids, liquid and gasses?

6.  What is the definition of tension?

7.  What is the definition of compression?

8.  The the "Bridge to Nowhere" challenge we did in class, where did you see tension and compression in the bridge?

Re: 2/14 MS Chemistry update and homework due 2/21

Hi all, 

We have made the decision to cancel Chemistry Feb 21st, due to weather. Our concern is that temps will likely be below freezing and we don't want anyone feeling pressured to drive through that. We will resume class next week. Thanks and stay warm!

Hi folks,

Today we started our new block which is the states of matter.  We learned that atoms join together to form molecules and that molecules join together to form solids, liquids and gasses.  In the upcoming weeks, we will get up close and personal with all the states of matter and learn what temperature has to do with all this.  We also did a gameshow that allowed everyone to put their knowledge to the test.

For homework this week answer the following questions.  (Short homework this week since most of class was taken up with the review game show.)

1.  What are the four major states of matter?

2.  What one word makes the difference between each state of matter.  In other words, what is the major difference between each one.

3.  Do molecules change shape or form depending on which state of matter they are in?

4.  In the Universe, what is the most common state of matter?

5.  Draw a picture of several molecules in each of the 3 states of matter.  In other words, draw 3 different picture where each one represents several molecules in a state of matter.

Answers:

1.  Solid, liquid, gas and plasma.

2.  Bonds.  The major difference in each state of matter is the type of bonds that hold it together.

3.  NO!!!  Only the bonds are different.  The molecules don't change.

4.  Plasma

1/24 MS Chemistry Recording - Valence electrons

Part 1

Part 2

1/24 MS Chemistry update and homework due 1/31

Hi folks,

This week we dove a bit deeper into the periodic table by looking at valence electrons and molecular bonding.  We are going to do more of this next class as well.  It's a little tricky.

For homework this week, please answer the questions below.

Also!!!!!  Go to this website and click on the play button.  Have fun playing with the different simulations here.  This is a great way to review what we've been working on so far and really solidify the concepts.   At the site, you'll see a link that says "game".  There are four games here.  Play all of them and try to get 4 or better for your score.  Please write down the game and the score you got so that I can see that you've tried these.  One thing that's tricky about this, the way they do the element box is odd.  It took me a while to get the hang of it.  I've included a little guide below to help you figure out what's going on.  Have fun and good luck!

1/17 MS Chemistry update and homework due 1/24

Hi folks,

Today we dove even deeper into atomic structure as we learned how to draw Bohr diagrams.  These will allow us to see how the electrons are configured in an atom and will allow us to predict how each atom will make molecules.

For homework this week please answer the following questions and do the enclosed worksheet.  I've included answers in a .pdf.  Be sure to really understand these Bohr diagrams.  I smell quiz material….:)

Draw Bohr diagrams of the following atoms.

1. Nitrogen

2.   Aluminum

3. Calcium

4.  Magnesium

5. Argon

6. Neon

7.   Helium

1/10 MS Chem update and homework due 1/17

Hi folks,

During this week and last week's class we spent a good bit of time with the periodic table and reviewed protons, neutrons and electrons.  The next few weeks we will be diving quite deeply into the periodic table and the language of atoms and molecules.

For homework this week:

Do the enclosed worksheet.  I've included the answer key so that you can check your work.  Beware, there are some isotopes and ions on the sheet so pay close attention.  This may be a little tricky so take your time on this.  I want you to fill out all the blank spaces on the table.  Let me walk you through the first one. On the first line, notice that the letter B is on the right hand side.  That is the atomic symbol for Boron so look up Boron in your periodic table.  Once you've found it, fill in the blanks.  For example, atomic number would be 5, protons would be 5, Electrons are 5 and Atomic mass is 5 + 6 so 11.  Since some of these are isotopes you want to make sure you add protons and neutrons to get the atomic mass.  Also, if you need to find the number of neutrons, be sure to use the atomic mass on the worksheet to find them.  It may be a sneaky, sneaky isotope.  For the second one, they don't give you the symbol but they do give you the atomic number so you can go from there.  Last but not least, look at the 5th one.  It says Fe+3.  That means it's a positive ion of iron so how many electrons should it have.  Be sure to check your answers on this.  Please email me if you're confused.
