Exam Review #3: Problems

We’ll review this first thing in class then go over a few more exam examples tomorrow.

See you then!

If you, like me, have always been curious why gold has always been so valuable compared to other elements, head over and listen to this report from NPR…

Gold and the Periodic Table of the Elements : Planet Money from NPR: “So we’re down from 118 elements to 30, and we’ve come up with a list of three key requirements [for money]:

- Not a gas.
- Doesn’t corrode or burst into flames
- Doesn’t kill you.“

Can’t argue there, I guess.

Sounds like a good exam question

Yay Periodic Table!

How’d you do? Make a 100?

Try Element Hangman.

Enjoy!

Remember to read up on the Chemical Reactions section of our textsbook so that you can get to work (with your lab partner) on a lab/demonstration/video/podcast or paper to reflect what you’ve learned.

Please have these posted up on your blog by Thursday. This will reflect you grade on Test 6.

Also let me know if you need any specific materials or chemicals.

Enjoy!

Honestly, you all impressed me so much on Friday with your teamwork and success on those 10 balancing equations we attempted in class. You literally reminded me that I have the best job in the world (well, besides being a squirrel trainer in a traveling circus).

Great work, everyone!

Yay First Period…

Yay Second Period…

Yay Fourth Period…

And special congrats to Period 4 for knocking out 10 Advanced Level equations…

See you tomorrow with donuts/doughnuts/howevertheyarespelled!

Here is the sheet we worked on in class that is due tomorrow…

If you need more practice, head over to the JLabs balancing game here.

Enjoy!

What is life?

Will we find life on other planets or moons (or asteroids) in your lifetime??

Titan’s haze could hold ingredients for life: “In an experiment exploring the chemical processes that might be going on in the hazy atmosphere enshrouding Saturn’s largest moon, a University of Arizona-led team of scientists discovered a variety of complex organic molecules – including amino acids and nucleotide bases, the most important ingredients of life on Earth.”

I think so. The jury is still out. Yet another reason we need you all to be scientists!

And for my benefit…

By 8am Wednesday (September 8, 2010 8:00 AM EST), find and blog about a compound that you think is incredibly interesting. Tell me why based on its properties in your own voice.

+1 on any test you choose (remember, tests are 10 points each) if you complete this in time.

Here’s a good place to start:

List of inorganic compounds – Wikipedia, the free encyclopedia

Even better (+5 points) if the compound you choose is on display and you can point it out at the American Museum of Natural History (which we’ll visit on our D.C. Trip next month!)…

Anyone go see a fireworks show? Mary Hudson, Laura, Anna and I saw a great show here in Asheville from the top of a tall mountain (hiking up a steep road with an infant is much more difficult than it sounds).

Anyway, as we watched the show, I thought about you all and wish we could have spent some time studying the chemistry behind firework colors, explosions, etc.

So, here’s the next best thing

Pure chemistry (and awesomeness)! It’s all about science (of course).
