Chemically Unbalanced

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

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

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!

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

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!

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!

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

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

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

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

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

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.

This lets you control all the variables, and will construct a graph for each different option you can pick.

Interactive program that lets you control the constant in each experiment.
Or Click Here...
Helps represent the graphs we have been looking at in class (click on graph and drag mouse).
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.

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!

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!

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!

This is a site i found helpful, its not really as in depth as some of the other sites, and theres no interactive component, but i did find that it did lead a lot of interesting things, and could possibly be useful in the future.

This is an interactive site that I found was useful but also helped me understand a little bit more about gas laws. http://accad.osu.edu/~midori/GasLaw.html
