Alka-Seltzer Lab Wrap Up

Overview of Class Time:

Today we did the third and final part of the Alka-Seltzer Lab. In part two of the lab we had to test the different reaction times when you drop Alka-Seltzer into a film canister filled with a certain ammount of water. In part three we got to choose our own variable, some chose to test with warm water, some with cold and some tested with a larger ammount of Alka-Seltzer.

Experimental Design & Alka Seltzer Lab

August 27th

Today in class we started the Alka-Seltzer Lab. 

1. We went through what the problem of an experiment is
2. We learned that a vaild experiment includes variables:  

• Independent variable- what you are testing
• Dependent variable-what you are measuring
• Controlled variable-what is being kept the same

                                    ** See Moodle for full notes

     3. Keep collecting data until you get the same results. 

The lab variables were the film canister, the Alka-Seltzer tablet, and water.

Each trial we did something different, like changing the amount of water. 

We timed each trial.

Policy Wrap-up and Procedures

August 26th

• We took a non-graded pre-test in order to collect data about our initial knowledge of chemistry.
• Again, in order to sign into moodle, (which if one is reading this they successfully have) use your normal school login. 
• To send in a scribe post, send it in e-mail format to Mrs. Mandarino until further notice.
• Bring in your science goggles tomorrow!
• For homework, read text pages 7-11. 
• Begin thinking of ideas for solving the Alka-Seltzer Lab.

First Day Policies and Tools

August 25th
• Class started with assigned seats.

• Everyone picked up 5 different papers.
- 3 half sheets (including the syllabus) to put in a composition notebook
- a safety contract that needs to be signed by you and your parent
- a student information sheet which you need to fill out

• Log on to your Moodle account and check out the chemistry page- it
gives the homework, an outline of the unit, notes from class, and labs.

NOTE: You may only use a composition notebook (not a spiral) and you do not need to bring your chemistry book to class, unless told otherwise.

Welcome Post

Let the fun begin!

Welcome! You have sucessfully found our class blog. This is a place to see what happens in class everyday. It can help you review; ask a question that you didn't get a chance to ask in class; or find out what you missed if you have been absent. Please feel free to share this blog with your parents.

Before you begin blogging, please view the video to learn how to become an author on our blog. Please be sure to choose an appropriate screen name. This name should allow me to identify you while also maintaining your privacy. Please do not use your last name! Before you dive into blogging, please read this entire post.

How to become an author on our blog

What is a scribe post?

When we think of blogging, many times we think of posting ideas on facebook or twitter. While we use blogging for social networking, it can also be used as a valuable educational tool. Every day one student will be responsible for creating a post describing what went on in class that day. These posts are called scribe posts and will be the bulk of our blog. The person who makes the scribe post for the day will assign the scribe for the next post the following day in class. Once you complete your post, please make sure to cross your name off the scribe list on the next post.

Labels
Labels are also known as tags. They are important in keeping our blog organized. They will also help me keep track of your contributions for your grade. You must include the following 3 labels:

1. Your name = please use your first name and last initial
2. The unit we are studying = see moodle for appropriate unit names
3. The type of post it is = Most will be "scribe" posts. Later we will introduce the "on my mind" post.

Digital Ethics!
Remember, blogging is a very public arena. Anything you post on the internet, will always be on the internet. Even if you delete a post, it may remove it from the blog, but copies of the post may exist all over the internet. Therefore, we must be very careful to respect your privacy and the privacy of other classmates by:

1. Using only first names.
2. Never posting any pictures of ourselves.
3. Never including information about activities in our own lives.
4. Always using good judgement.


Blogging rules to live by!

1. Blogspaces are classroom spaces. Speech and actions that are inappropriate for class are also inappropriate for our blog. Please remember to always be respectful.
2. NEVER give out or record personal information on our blog. Do not share anything that you do not want the world to know.
3. Remember, our blog is a public space. If you put it on the internet, chances are that it will remain on the internet for a very long time. These posts may effect your future. It might be possible for a future employer to discover things about you through thoughts you posted in your younger years. Be sure to post thoughts that you are proud of.
4. Never add a link to your post that you have not thoroughly read. Make sure you want to be associated with the link before you add it to your post.
