How about a nice cold shower? (8-31-11 Measurement)

ANNOUNCEMENTS: 1.) There is a lab tomorrow on something interesting and related to chemistry. 2.) There will be a quiz on Friday on measurement (sheets in notebook).

HOMEWORK: There isn't any assigned homework but Mr. Paek suggested that we complete our lab write ups because we will have homework tomorrow.

IN CLASS:

• First we watched a "new" safety video. You would think after all the lame and cheesy videos that have been produced they would learn, but I guess not. But to lighten the spirits Michael Dillon starting laughing in the middle of the video and didn't stop for a solid 5 minutes.


• Then we watched Jordan take a nice cold shower. Apparently the shower head can't control itself and sprayed all over, getting Jordan a little more wet than expected.


• We then spent about 10 minutes taping worksheets into are notebook. (If you were absent see Mr. Paek for the sheets).


• Finally we ending class with learning measurements. We learned that when measuring you should only have to guess on one number. We also learned that you are supposed to measure liquid at its lowest point of the top (meniscus) if that makes any sense.

Alka-seltzer lab- Tuesday, August 30, 2011

Announcements: You can make your post on here as annoying as you want as long as it meets the requirements basically.

Homework: Lab Report Sheet (due Friday)

At the start of class Mr. Paek showed up the class blog and pointed out a few errors on format and spelling and such. He also showed us some example posts from previous classes to inform us that in the past kids had done some pretty strange things. Then we quickly moved on to the next part of class which was working on our lab reports. These are Due Friday and whatever wasn't finished in class is to be done for homework within your group.

*Follow format of report and split up the work with your partner. Make the procedure in a numbered list.

*In order to make a graph; on moodle click "make a graph" then simply select which you'd like to use..

After all of these instructions we worked on our lab reports using miniature lap tops. For the last ten minutes of class we watched as Mr. Paek demonstrated why you should not to light bubbles on fire. They will explode because of the gases.

First Lab Continued - 8/29/11

Announcements: Don't forget to get the right pair of goggles for class! Mr. Paek will be giving points for having them!

Homework: None :)

Today in class, we generally continued on with the Alka-Seltzer lab that we began on Friday. We had part one of the lab for homework. Then, Mr. Paek began to go over with us, as a class, part two of the lab. Mr. Paek stressed the importance of writing a procedure so that "if your mom were to come into the classroom and didn't know anything about chemistry, she coud complete the lab step by step."

We then went over the post-lab questions to part two. We identified the variables of the lab:

-Independent: (what you change) amount of water

-Dependent: (what you measure): time

-Control: (what you keep the same): amount of alka-seltzer, film canister, the location of the experiment, type of liquid, temperature of liquid.

After this, Mr. Paek described to us how to make and record a data table: you think about what you're changing (that's a column), what you're recording (that's another column). You put in your correct data and bam, it's as simple as that! An example for part two of the lab would have two columns: amount of water and reaction time in seconds.

Then we got to finish the third and final question of the second part of the lab, which brought us to part three.

Using the same partners we had on Friday, we got into our groups and began to conduct part three of lab. This part of the lab is a chance for us to create our own experiment with the alka-seltzer. We got to choose the independent and dependent variable with our partner, and began to conduct our labs. We recorded our data and began to work on the writing part of the third part of the lab, which is the experimental design. This includes:

1. Problem

2. Hypothesis

3. Variables

4. Procedure

5. Data

6. Conclusion

Tomorrow in class, we're taking the first twenty minutes to type this up. The experimenting brought us to the end of the class, and that was it for today!

First Lab 8/26/11

Homework: Finish any unanswered questions for part one of the lab.

1. First, we got our numbers for our personal rolls of tape for the year.

2. The second thing that we did Friday was get our journals ready for the first unit.

- Taped in Unit one schedule, Objectives, and the Alka-Seltzer lab

3. Next, we took a short amount of notes which were on variables:

-Independent: What you change (temp, food, light)

-Dependent- What you measure (time, distance, behavior)

-Control- What stays the same (type, number, location)

-Qualitative Data- Observations that are generally subjected (moth moves into light)

-Quantitative Data- Observations that are objective (time)

4. Next, we moved on to getting our blogger accounts set up.

- Passwords, display names, etc.

- Accept invitation to blog from Mr. Paek on your student email

- Log in: id#@glenbrook225.org, with your password to sign into the computers

5. Lastly, we began the first part of the Alka-Seltzer lab.

- Filled film canisters with water, put an Alka-Seltzer in, closed the lid, faced down, and observed.

-Alka-Seltzer creates bubbles which take up the left over room in the canister

-Causes a build up in pressure making the canister act as a rocket, shooting towards the ceiling when the cap bursts off.

The Scribe List

This is The Scribe List. Every possible scribe in our class is listed here. This list will be updated every day. If you see someone's name crossed off on this list then you CANNOT choose them as the scribe for the next class.

This post can be quickly accessed from the [Links] list over there on the right hand sidebar. Check here before you choose a scribe for tomorrow's class when it is your turn to do so.

IMPORTANT: Make sure you label all your Scribeposts properly (Your display name, unit title) or they will not be counted.

Digital Ethics

Much of what is written here is from a teacher experienced with using the web as a forum for us to share our learnings and reflections. Darren Kuropatwa writes, "Blogging is a very public activity. Anything that gets posted on the internet stays there. Forever. Deleting a post simply removes it from the blog it was posted to. Copies of the post may exist scattered all over the internet. I have come across posts from my students on blogs as far away as Sweden! That is why we are being so careful to respect your privacy and using first names only. We do not use pictures of ourselves. If you really want a graphic image associated with your posting use an avatar -- a picture of something that represents you but IS NOT of you."

Reflect as you watch this.



Two teachers in the U.S.A. worked with their classes to come up with a list of guidelines for student bloggers.

One of them, Bud Hunt, has these suggestions, among others:

1. Students using blogs are expected to treat blogspaces as classroom spaces. Speech that is inappropriate for class is not appropriate for our blog. While we encourage you to engage in debate and conversation with other bloggers, we also expect that you will conduct yourself in a manner reflective of a representative of this school.
2. Never EVER EVER give out or record personal information on our blog. Our blog exists as a public space on the Internet. Don’t share anything that you don’t want the world to know. For your safety, be careful what you say, too. Don’t give out your phone number or home address. This is particularly important to remember if you have a personal online journal or blog elsewhere.
3. Again, your blog is a public space. And if you put it on the Internet, odds are really good that it will stay on the Internet. Always. That means ten years from now when you are looking for a job, it might be possible for an employer to discover some really hateful and immature things you said when you were younger and more prone to foolish things. Be sure that anything you write you are proud of. It can come back to haunt you if you don’t.
4. Never link to something you haven’t read. While it isn’t your job to police the Internet, when you link to something, you should make sure it is something that you really want to be associated with. If a link contains material that might be creepy or make some people uncomfortable, you should probably try a different source.

Thoughts on the videos or on these guidelines? Any other guidelines you'd like to add?

Googled

Copied in it's entirety from Seth Godin's blog.

---

A friend advertised on Craigslist for a housekeeper. Three interesting resumes came to the top. She googled each person's name.

The first search turned up a MySpace page. There was a picture of the applicant, drinking beer from a funnel. Under hobbies, the first entry was, "binge drinking."

The second search turned up a personal blog (a good one, actually). The most recent entry said something like, "I am applying for some menial jobs that are below me, and I'm annoyed by it. I'll certainly quit the minute I sell a few paintings."

And the third? There were only six matches, and the sixth was from the local police department, indicating that the applicant had been arrested for shoplifting two years earlier.

Three for three.

Google never forgets.

Of course, you don't have to be a drunk, a thief or a bitter failure for this to backfire. Everything you do now ends up in your permanent record. The best plan is to overload Google with a long tail of good stuff and to always act as if you're on Candid Camera, because you are.

Welcome to Period 8 Chemistry!

Period 8, welcome to our blog!  I am genuinely excited to have you in this class. This is going to be a site by you and for you.  It'll be a place to share your knowledge with fellow classmates, to reflect on what you've learned, and to learn concepts that you may have missed in class.  You will only have to write 3-4 of these per SEMESTER.  Please do yours the best that you can.  Your class and others are depending on you and will appreciate it.  We'll talk more about the details later.

Just remember, you must add at least 2 labels to every post.

1. Your screen name

2. Unit the post is about 

Scribepost Format

Title: date and topic of day - for example - 11.13.10 - Measurement



Announcements - put here in bullet or numbered format


Homework -  put here in bullet or numbered format


Body:  this is solely up to you how you do this.  please remember, you don't do many of these - do yours the best that you can - for yourself and for your classmates.  Headings in bold, pictures, videos, examples, announcements, homework are some of the elements that make for a successful post.


End with a pick of who the next scriber will be.


Labels: Need 2 of them:

1. your display name (this will be your first name and first initial, no caps, no spaces)
2. unit name (check moodle for proper name of unit)
