In this unit, I didn't really need too many external resources but here were a few links that helped me study for this unit.

Happy Birthday

I don't know how many people are posting about this, but since today is Mrs. Frankenberg, I figured I'd post about it as well as write a quick summary of the last unit. I found this unit to be one of the more interesting. Maybe it was the fact that was easier or the fact that we got the burn different chemicals, this unit was a welcomed change from the previous ones. Probably, the only "boring" activity we did was the spectrometer lab: though I realize its importance. What can I say, this unit was pretty fun!

Long Test

We just took the Unit 9 test for electronic structure and periodic trends which turned out to be a pretty long test of 50 questions. Luckily, the questions were pretty straight forward and short. Even with it being 50 questions, I got done with a bit of time to spare which is always rather calming to the nerves. We'll just have to wait and see what happens.

Finally an easy quiz

We took a quiz on Friday and for once I can say it went well. We'll see if this becomes a trend. ;)

Spectrometer lab

This lab was not tremendously fun. Basically in this lab we used an analog machine to test how different wavelengths of light transmitted through different chemicals. We have yet to analyse the data. Hopefully then it will get a little more interesting.

Flame Test Lab

The flame test went rather well there were many pretty colors and I learned a lot about light as a wave, an emission of energy. The lab was really cool.

R.I.P. my chem grade

Wow that test was rough. Granted, I didn't have as much time to prepare for it compared to previous tests, but looking back I should have made time. I guess it's come back time. Hopefully the next unit is easier. Hopefully.

Stressed Out

Tomorrows the test and I have little time to prepare. We'll see what happens tomorrow

Crystal pine tree

Not so much to do with class but in chem club we made Crystal Christmas trees. I'm really happy with how mine turned out.

Titrations

We just learned about titration problems and, I'll be honest, they are long and rather confusing. I hope I get to learning them before the test. Here's a few videos I found that might help

Whoops

Today was a practice day for the lab. Our titrations turned out really pink. Hopefully we can do better for the real lab.

pH and Logs

We just started the new lesson and so far it's been ok but we just got to molarity to pH conversion.
This meant that we are utilizing logarithms. It's not difficult but it's not the most pleasant thing in the world. However this video will hopefully save me. :)

When scrounging on the internet

I found a few more links while on the internet. Not the most useful, granted, but still worth mentioning.

Quizzes

Quizzes just came in. I'm off to decent start but from rumors I hear this quarter will be difficult. So far it's been ok but we shall see what happens... I guess

Murder Lab

A few days ago, we did a simulation of a murder case in which we utilized our knowledge of dilutions and chemical reactions to solve the mystery. Lab report is due on Tuesday. I'm excited to see if we're right but also terrified.

Dilution of Food Colouring

Today we did a dilution activity with food colouring and it was tremendously useful in understanding dilution problems. Quiz is on Monday and I am nervous about it since it's covering topics from last semester.

Last day of lab

Today in lab we wrapped up loose ends by weighing our copper and working on the equations linked with this project. Overall I found the lab to be a great hands-on experience with what we learned in class.

More pics from lab

Second day of lab where we removed the nail and any liquids from the copper. Now we just need to wait for it to dry.
