THE CHEMISTRY MUST BE RESPECTED.

If you need a reason to not sleep through class, this thread of serious lab accident stories gives you a pretty decent one.

Note that most of these were chemical incidents perpetrated by biologists and engineers.

How many of your other classes can potentially prevent you from dying a horrific death in the lab?

Here are more stories.  There’s also a video, further down the page, that shows barrels of sodium being dumped into a lake.

I’m thankful to have avoided lab injury, except for one lightly-THF-contaminated needle stick and a few small lab fires.

End electron inequality now!

I thought I’d share this article with you guys since it’s very relevant to what we’ve been discussing in class lately.  We must all strive to promote atomic diversity and fair distribution of electrons within our chemistry.*

 

* APRIL FOOLS!  (Side note: your instructor actually thinks diversity and income equality are very, very important issues and she does what she can on both counts.)

Why study chemistry?

This may be hard to believe, but many students in an introductory chemistry class don’t enroll out of sheer fascination for the subject.  Chemistry is required for many degree programs, from engineering to environmental science to healthcare professions such as nursing or pharmacy.  It’s a challenging class that students usually take early on because it’s a prerequisite for upper-level classes for many majors.  Many students haven’t learned how to study effectively by the time they first encounter a chemistry class, and consequently they don’t do well and end up resenting the subject.[1]

It’s unfortunate that chemistry isn’t better-loved among the general public, because a bit of scientific literacy can be very, very helpful.  For example, if we all had a solid understanding of chemistry, no one would be fooled by the sort of fearmongering that obsesses over any food ingredient that has more than a four-syllable name.  The market for expensive, pseudoscience-laden specialty bottled water would likely shrink if everyone understood a few basics about the structure of water (and just how clean tap water is in the US).  And no one would worry about dying a slow death at the hands of a microwave oven, because we would share an understanding of how light in different regions of the electromagnetic spectrum interacts with molecules!

Chemistry classes lay the groundwork for understanding these concepts and many more, but it is ultimately up to students to apply what they learn in the classroom to what they encounter in everyday life.  So, students, if you want to get the most out of your chemistry class, here’s a curiosity exercise for you: look around you.  Ask questions about what you observe.  Then, using your knowledge of basic chemistry concepts, try to answer your own questions!  Always sanity-check your answers to see if they make sense, too.  This can be tricky at first, but if you keep doing it, you’ll develop a much deeper understanding of the world around you–and a much deeper appreciation for chemistry.[2]

What is this site?

This is my teaching site–I’m starting as an adjunct prof in 2015!  In addition to hosting class materials, I have a few links and resources posted for my students and for other instructors.

I also have a blog here.  This is a space for me to post things that are relevant to what my students are learning and that I hope will stoke their interest in chemistry.  (It’s a cool science, and it makes for some good photos and videos.)  Comments, interaction and curiosity are encouraged here–I’m happy to discuss anything I post, and I’m also open to fielding questions.

With that said, I think this Caltech page on snowflakes is fitting for the first interesting bit of chemistry for the new site!  If you’re curious about crystal growth or just want to look at pretty snowflakes, check it out.  I spent a lot of time studying crystals during my PhD, but not snow crystals–good thing, since it doesn’t snow much around Santa Barbara!
