Safety Part 2

Today's class we continued our discussion on safety and started to prepare for our first lab. We watched another clip from the ACS safety video. This shorter clip had to do with good lab techniques. There are several points that I think are worth highlighting.

1. The video made a point of telling us that it is always smartest to pour liquids from large stock bottles into smaller containers that are easier to manage in the lab.

Ahh...the memories

2. The point of mixing acids is an important one but not done very often in our class. Acids should always be poured into water, not the other way around. "Do what you outta pour the acid into the watta" I know lame but I learned that in high school myself.

3. The video also commented on how we always pour out of stock bottles but never back in. If you have too much of a chemical dispose of it properly but do not put it back into the stock bottle.

4. Remember never mouth pipet!!

After that we briefly discussed how to do the pre-lab for Monday's Observation Lab. We will discuss the data tables on Monday also. Lastly we briefly talked about the unit objectives that were handed out. These are just the main topics for the current unit. They will be handed out at the beginning of each unit. Remember that if you missed a handout for an absence please go to our moodle site to download them. The last thing we did was took our safety assessment on WebAssign.

V-I-C-T-O-R-Y!!!

Have a great weekend and go Titans!!
Oh yeah our first student scribe is...Kathryn J

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 Scribe Posts properly (Your Name, Unit Title, Scribe) or they will not be counted. Please only choose those names that are in bold as they have ative blogger accounts

Achtung Baby!!

Today was all about safety. Our discussion centered around the Flinn Scientific Safety Contract. Also we watched clips from the ACS safety video. The first part of the discussion talked about appropriate laboratory attire and behavior. The movie clips were hilarious but informative as Mr. Lieberman was able to link them to our classroom. He showed us the location of all the safety equipment and some special safety considerations for our classroom. The second part of the discussion talked about what to do in case of an emergency our an accident in the laboratory.



Mr. Lieberman also showed us some cool demos that go along with the discussion. The first demo involved "Dave" the mannequin and acetone. This showed us how ordinary household substances can be dangerous in the lab and also how "horseplay" can result in serious injury. The second demo involved an egg and concentrated sulfuric acid. This showed us how sensitive the tissue in our eyes is and how quickly an eye injury could occur. The last demo was the vapor ramp demo. This showed the volatility of organic compounds and how we need to be careful with them near upon flames as the vapor is extremely flammable.

Now that we are all experts on safety...let's dance!!

Creating A Post

The video below will help you with creating a post below


There are two types of posts that you will create: 
   1. Scribe Post (scribe):  This is a daily entry of what happened in class that day
  2.   On My Mind (OMM):  This is an entry that you submit at any time to share something that is on your mind.

Every post should have at least three labels:
  1.  "scirbe" for a scribe post or "OMM" for an on my mind post
  2.  your username
  3.  the topic addressed in the post
