Chem Lab Practical

I just completed my lab practical for principles of chemistry. Not trying to brag or anything, but it was really easy. I could see how it would be difficult for people who aren't comfortable with doing laboratory stuff, or for people who aren't as big a dork as I am. =)

Here's what they make you do:
  1. Gravitational filtration, i.e. pour something into a funnel with a piece of filter paper in it.
  2. Vacuum filtration, same thing only with a Buchner funnel and a water faucet set up.
  3. Light a Bunsen burner, adjust it to a luminous/"cold" and a non-luminous/hot flame
  4. Read a barometer, buret, graduated cylinder, and thermometer.
  5. Weigh a flask, put 10mL of a liquid into the flask with a volumetric pipet, weight the flask + liquid
  6. Calculate the density of liquid from the measurements.
I'm guessing upper level chem labs will involve more difficult processes. It's still a relief to know that I'm done with it though.
