Chemically Unbalanced

Greets from the West Side

2010-10-11T23:25:00.000-07:00

Hello class, hope your tuesday is going well. Things are nice and dry here on the West Coast.

As for things to do today, if you look in unit 2, you will see several concept checks. I would suggest that you can play catch up today and do any missing concept checks from the past unit. After that, start on the current unit. We've covered through the combined gas law, so that means there are 4 concept checks and 1 quiz that you could do.

I figure that you should be able to get through at least the first 3 and the first quiz. Good luck on that and I will see you all tomorrow.!

Mr. I

An Interesting Applet

2009-01-15T13:34:00.000-08:00

Here is an interesting applet that I think helped me learn a little more about chemistry. It is set for a younger age group but it still proves to be useful. It is http://serendip.brynmawr.edu/sci_edu/chemsites.html#1

Sick day again...

2009-01-09T07:17:00.001-08:00

Hey class, today you can work on Moodle, your homework assignments. Remember that you have one week before your mark is set! Also, you can work on your projects as you will only have one more class period next week dedicated to work on it.

For Physics 20, since it will be just you gals and guys, I have a DVD in the chem supply room next door. It should be sitting out on a black DVD book on the counter. It is Bill Nye: Physics greatest discoveries. You can watch this for the class period. Good luck!

Hello sick day

2008-12-03T06:53:00.000-08:00

Well, I'm not feeling well today, run down with a headache to start my morning so this will be quick.

After your quiz, you can continue to work on any number of project, the keynote, the wiki, concept checks.

If you are unable to access the wiki still, you can post to the blog instead.

Later

Work for Tuesday/Wednesday

2008-11-17T19:38:00.000-08:00

Well a quick update for while I'm gone.

1. Missing stuff - Please finish your extreme gas & lighter lab for the end of the week.
2. Review material - practice material will be posted on Moodle. You can access it there.
3. Concept checks - some of you are getting behind here. Check your grades on moodle to see your homework mark!
4. Keynote Project - For the last 1/2 hour next Monday we will be looking at what you've done (i.e first draft). Every group should have something considering you will have had 2.5 class periods!
5. Wiki - I've started a wiki to play with (http://stirlingchem.wetpaint.com/). Everyone has been invited, so attempt to login. I used the email provided for the blog. Once in, experiment a bit by editing your previous posts. Clean them up and remove the nicknames, replacing with real names. Also, you can delete the comments part of the postings.
6. Test on Friday. I will be back Thurday to answer any questions that may arise.

See you Thursday!

avogandro's law

2008-11-09T17:42:00.000-08:00

http://www.chm.davidson.edu/ChemistryApplets/Gaslaws/DaltonsLaw.html
this site talks a little about the formulas!
http://www.lon-capa.org/~mmp/applist/pvt/pvt.htm
This site shows you the ideal gas law relationships and you can choose the constants and draw on the graph!

Avagadro's and Moles

2008-11-07T09:20:00.000-08:00

Okay, so I have been getting a little behind on the work because I was stuck on the concept of Avogadro's Law and the concept of moles.... This one site helped me a little to understand Avagadro's reasoning a bit, and this video just helps with the concept of moles (hehe prepare yourself though!). And to top it off, this site has almost all the formulas for the laws, and works through each one with actual numbers, step by step. Have fun! ^_^ lol

Avogadro's Number and the mole.

2008-11-07T07:46:00.000-08:00

Watch out for this one, I found it really helpful, but its buried in a huge pile of useless fluff.

Ideal and Avogadros Laws

http://www.chm.davidson.edu/ChemistryApplets/GasLaws/

This has all of the gas laws. Look at it and see if you like it!!!

Ideal Gas Laws

2008-11-07T07:30:00.000-08:00

This is an applet showing the ideal gas law. You need to scroll down a little bit to see it. It is an interesting little site but if you put your mind to it, it actually makes alot of sense. http://www.chm.davidson.edu/ChemistryApplets/GasLaws/GasConstant.html

Ideal and Avogadros Laws

2008-11-07T07:27:00.000-08:00

This has all the different types of gas laws. See if it works for you!!!

Avogadro's law

2008-11-05T08:46:00.000-08:00

This post has a little bit on Avogadro's law it has both text and an applet although the applet is a little low tech it is supposed to show the main parts of this gas law. In the applaet you actually have to problem solve. This should be an new direction with the posts.

Or Maybe Click Here
This is the site Mr.I showed us in class, he/you didn't post it when he/you said he/you would so I thought i'd do it for him/you. (you will have to go to the bottom of the page in the sixth last point where it says "click here for the applet") I find it really helpful and fun.

Gas Laws 2 - Assignments

2008-11-03T08:17:00.001-08:00

1. Like last week, we will need some postings & comments. Remember 1&2 as the minimum, but feel free to go above and beyond. Also comments should be constructive about what was useful and why.

2. Make a second sheet that contains info on the second chapter (This would be the McGraw Hill Ch.4 pdf file) and upload it. I prefer pdf format please :)

3. There are 2 more concept checks that need to be done!

4. Lastly, we are starting our first project! We will discuss that during monday afternoons class!

Pressure factors

2008-10-30T08:57:00.001-07:00

I don't know about you guys but I can never find out the conversion factors for pressure so I went out and found a site that does it, take a look at it and let me know if its correct!

http://www.csgnetwork.com/prestableinfo.html

Gas Law - Assignments

2008-10-27T21:04:00.000-07:00

Well here is an update on things that you need to to this week.

1. Check that you uploaded your assignment (gas law sheet) correctly. I've checked and not everyone has uploaded and most people need to make changes.

2. News Forum - New posting that needs your response.

3. Concept checks. There are 3 that you can do. You can redo anyone you wish, but there is a 5hr delay between attempts.

4. A survey to get some general info about your learning style.

Thanks!

http://library.thinkquest.org/10429/low/gaslaws/gaslaws.htm
This is a site that has the properties of gases and all the different types of laws.

gas laws! WOOT

2008-10-21T08:48:00.000-07:00

hey i found some interesting(-ish) sites.
click here to learn about Boyles law
and click here to watch a video/slideshow about the gas laws in general.

hehe so there they are! ^_^

Charles' Law

2008-10-20T22:50:00.000-07:00

Here is the site for Charles' Law. It really helps explain how to do the calculations.

http://www.ausetute.com.au/charslaw.html

If you go to the top of the page it will have a link to Boyle's Law.

It basically explains that at a constant pressure, volume of a gas is directly proportional to the absolute temperature. (So at a constant pressure, if the temperature is doubled, the volume of gas is also doubled).

Boyles Law and Gas Laws

2008-10-20T13:38:00.000-07:00

Here are a couple good sites:
http://www.chm.davidson.edu/chemistryapplets/gaslaws/BoylesLaw.html
(has lots of info and can do experiment at the bottom, relating to pressure and volume).
Click here for a site that has helpful info and diagrams relating to atmospheric and gas pressure.

Welcome to Gas Laws

2008-10-19T22:22:00.000-07:00

Well here we are, a new unit and I'd love to get things started off right. Follow the instructions below.

Here are some links to help you learn the concepts. Click on them and check out each one.

Gas Law Basics - Good to begin
(good link, go over the first 3 parts)
Boyles Law
(nice demo to show the key principle)
Basic Boyles Law
(this is OK, not my fav)
Charles Law demo
(like the Boyles law one above)
Charles Law Primer
(nice and simple)
Gas Properties
(not exciting, but covers everything)
Pressure and Temperature
(this is fun to play with. What is happening here?)
charles, boyles & avogadros law
(this one is good if you just don't worry about avogadros stuff. We will cover it later so it's not bad to learn now)

Look on the Moodle site for help with your Boyles & Charles law assignment for Tuesday. Also, I'd love your comments about these links. Which ones were good, which ones sucked?

HW for Thursday

2008-10-15T21:39:00.000-07:00

I want you to create a Pictorial study sheet to review.

1. Open a pdf chapter. You can find them in my public folder on the server. Remember how to get there?

2. Open them by double clicking. The top menu bar contains the things you can do.
The first two keys are to move through the pages, the next two are to change size, the next three are move, select text and select a picture and the final 4 are for you to guess :)

3. Using the select button, drag around a picture, data table or chart that you think will help you study for the test.

4. Select edit & copy or hit the open apple & C key.

5. Then I want you to open a Microsoft word document (finder - applications - microsoft - microsoft word) and click edit & paste or open apple & V key.

Try to add some text with your pictures to make them easier to follow. Here is mine, I will photocopy it for you with yours as well.

Your Review page must include 4 pictures, each with text. Try to work together as a class to split up the work so that you have stuff from each chapter.

Good Luck!

Electronegativity

2008-10-15T09:32:00.001-07:00

Here is a little electronegativity clip of how they share, and what there number is for each of the common elements.

http://www.youtube.com/watch?v=Kj3o0XvhVqQ

VSEPR site

2008-10-15T09:18:00.001-07:00

http://www.green-planet-solar-energy.com/vsepr.html

this is a site on VSEPR theory.... it seemed to do a good job on explaining the whole thing.

electronegativity and crystals

2008-10-15T09:11:00.000-07:00

I thought this was a cool site just because it showed you some different 3d structures of a bunch of different crystals.

http://socrates.berkeley.edu/~eps2/wisc/geo360/mov.html

I just thought they looked cool!!

another site i found is on electronegativity and it explained it good!

http://chemguide.co.uk/atoms/bonding/electroneg.html

Intermolecular Forces

2008-10-15T09:09:00.000-07:00

http://www.ausetute.com.au/intermof.html

This website also has information on the other topics, so not just the intermolecular forces.

Cool Lewis Dot Diagram Video

2008-10-15T09:06:00.001-07:00

http://www.youtube.com/watch?v=y6QZRBIO0-o

This is a video on how to draw Lewis Dot Diagrams.It is a bit slow so it will take about 5 minutes to go through it all!!!

Home work assignment

2008-10-15T09:06:00.000-07:00

this site I found is on electronegativity the only part that might be difficult is trying to understand the formula on the size of the chlorine and fluorine atoms. But it is pretty easy to work around.

http://www.chemguide.co.uk/basicorg/bonding/eneg.html

Periodic Table

2008-10-15T09:01:00.000-07:00

Hey this hopefully will be useful for you all.... we already know a bunch about the Periodic Table but this should be a little extra for you. It is quite interesting to play with.

http://www.touchspin.com/chem/DisplayTable.html

Crystal Structures

2008-10-14T09:32:00.000-07:00

http://www.neubert.net/Crystals/CRYStruc.html
This is kind of a cool site, has lots of information and a few examples that you can rotate around for better views on the structures.

Make your First Chem posting!

2008-10-14T09:09:00.000-07:00

Your assignment today (Wednesday the 15th) is to post a link to a website that would be useful for studying for your first unit test. This means it should be related to one of the following topics

Lewis Dot diagrams
Electronegativity
VESPR
Intermolecular Forces
Crystal Structure

Experiment a bit. Try inserting a clickable link, a picture or video. You can find those buttons here.

Also comment on 2 posts!!

Have fun and good luck finding something neat.
