Pretend to be Nice

Teacher-Moms, on the edge…

Out of your element.

Writing in general is out of my element, but since I’m a math person and I’m already flexing my English muscle by starting a blog, I’ll support my science peeps.

Several of my students are taking Chemistry and are asking for a lot of help lately.  I don’t want to constantly say, “you should watch the video again and take better notes” (although, that’s exactly what they should do) so I’ve been studying up so I can guide them in the right direction.

So what are you working on?

Moles

Psha!  I got this…nature channel here I come!

mole

Not those moles?   Ugh – here then.

2 moles per liter

 

That’s about the extent of my knowledge other than I know it involves math conversions (which is totally up my alley).

 

 

 

The short version:  moles are a unit of measurement when you’re talking about an amount of a substance.  The number of atoms in a mole is known as Avogadro’s Number (which I’m a big fan of because it reminds me of avocados and it’s exponential).

avogadros number

And teachers always use big fancy vocabulary to scare and confuse kids…psst!  stoichiometry is code for the math conversions you do when calculating molarity.  (See, it’s not scary.)

You should put it on your calendars now – nerdy people celebrate Mole Day (it’s on October 23 at 6:02).

My favorite part of every lesson:

When are we ever going to use this?

You’re not, you have to do it because teachers are mean and we don’t like you people.

Just kidding!  You should, at the very least, appreciate the how and why behind determining concentrations and dilutions.  People use it every day – from mixing cool-aid to spraying weeds in your yard.  The sad part is, people in general, are too lazy or didn’t pay attention in high school enough to do the conversions themselves so companies put very detailed mixing recipes on the labels, and the general population usually manages to screw that up too.  It’s just like automobile companies developing computers in cars that calculate your mileage – it’s a simple division problem people!  But that’s a whole nother rant.

You can get technical vocabulary and see problems worked out in a video here.

Here’s the cheater’s version (a calculator).

 

*A special thanks to my science partner-in-crime – Elizabeth Triplett.  We used to teach together and she made sure I didn’t screw anything up in this post.

    Chemistry was not my friend in school. I enjoyed the post and thanks for sending me the challenge entry. -OM

      I guess I didn’t mind the class…I really don’t remember much other than the final exam – which was AWESOME! My teacher gave us each a different test tube and week to figure out what was in it. +10 for each correct element/solute/[insert more fancy vocab here] and -10 for each one that was incorrect. I made a 90!

    Very interesting post. I like the challenge that OM presented to his readers. I would greatly appreciate it if you would check out my Facebook page: https://www.facebook.com/kbeezyisviral

    I like chemistry but forgotten it mostly. My favorite part was chemical equations and balancing them. After seeing what mole was I remembered studying about it in school but don’t know how I can use it in my daily life. Its because was never thought in school how to use it in daily life..lol.. Now reading this I will read about mole and how I can use the formula ..

    It hurts my heart everyday when I hear people say they don’t remember or even care about a subject because their teachers didn’t make it relevant. I promise – I lead AND follow with that information EVERY lesson!

    I like it – Mole Day 2014 is a huge success.

      My teaching partner and I would have big competitions and make the kids pick which was better – Mole Day or Pi Day (I usually won, because who wants to eat moles 😛 )

        Pies would be my favourite too.

    You forgot to include a photo of mole-asses. I mean the food, of course, not mole asses.

    How did I miss this post? I love this. Basic chemistry is relevant in our everyday lives. And it isn’t hard or scary really.

      I get a little nervous with chemistry, but my teaching partner gets nervous with math so we’re a good balance!
      (shock and horror that you missed that one 😉 but it’s ok – I know my mom missed the last Dear K-Evil or she would have called me by now! haha!
