LOVE Ionic Compounds Bonding and Naming

This is the week where we celebrate love.  In our class, we are also celebrating our ability to write chemical formulas and name ionic compounds.  Chemical nomenclature can be a tough concept for many students to grasp.  But, I believe that practice makes perfect...and that is what we do.  We PRACTICE until they are experts!  How do we do it?  

First, I teach them how to write chemical formulas for ionic compounds.  We take baby steps, though.  We talk about what makes an atom want to gain or lose electrons and whether or not it will form a cation or an anion.  Next, we talk about how to "drop and swap" to write the chemical formulas.  "Drop and swap" is the catch phrase that we use often to remind them to drop (the charges) and swap (the numbers).  We start with binary compounds first and then add in polyatomic ions for the tertiary compounds.

Second, we talk about how to name the compounds by using Sodium chloride as an example.  Most of the students know that the name of NaCl is Sodium chloride and not Sodium chlorine.  Using this information helps them to derive the naming rules on their own.  The students see that the name of the compound ends in -ide.

Last, we practice with lots of different activities and assignments.  Check out some of the ones we use below and share your ideas, too.  Comment with your BEST ionic compounds activity, include your email, and we will send you the Ionic Bonding and Compounds Mystery Picture for FREE.

Recap #GSTA17

How awesome was it?  The Georgia Science Teachers Conference has become something that I look forward to each year.  Lots of fun...lots of information...lots to share!  Here's a recap of some of the AMAZING ideas and resources that we received from GSTA 2017.

The Rocket Book Wave
I ordered one before I left the presentation where the idea was being shared. First, you simply record information (take notes, draw a diagram, etc.) in the notebook.  Next, you scan it with the app.  Whatever was on the page, gets enhanced, cropped, and stored into the cloud.  And get erases after you put it in the microwave.  I'm so excited about the ideas I'm having for using the notebook.  More to come once I receive mine in the mail and get to try it out.

Knowledge Hook
If you like Kahoot, you are sure to like Knowledge Hook.  It is very similar.  It can be used as a quick formative assessment tool.  Gives you great data to analyze!

This is something I'm super excited about using to create presentations more interactive.  We are not a 1:1 ratio school, but I think we can make it work in pairs.  Think about this...when you create a presentation to share with your students (like a powerpoint), you ask questions to your students during that presentation, right?  The result to asking that question is that one student typically gets to answer out loud.  How do you know what the 29 other students are thinking?  Spiral allows you to upload your presentation (or you can create a presentation in Spiral) and embed your questions.  Now, when you get to a point in your presentation where you would ask a question, every student with a device answers your question on the device.  It makes the presentation more interactive!  All of the students answer instead of that one student that raises their hand or that one student that you call on.  Check it out!

Snowball Fights
We went to a presentation about vocabulary in the science classroom and learned about this activity that the teacher used.  It's such a great idea!  We've used something very similar for swapping papers, but never thought about using it for vocabulary.  It's simple.  Start by having half of your students write vocabulary words on a sheet of paper (or pre-print them).  The other half of the students write the definitions (or pre-print them as well).  Each student then balls up their piece of paper.  When the teacher says "snowball fight", the students throw the paper balls.  Each students finds a "snowball", then finds their match.  Once all matches are found, the students ball up the paper again and have another "snowball fight".  I see this as being a great activity for practicing with vocabulary.

Do you struggle with creating higher DOK questions for your test or other assessments.  Lots of released test here.  It a great place to start!

I'm always in search for phenomena to teach concepts or problems-based learning lessons.  I'm excited about the resources that has to offer for biology, physcial science, chemistry, anatomy and physiology and so much more!

These are just a few highlights.  What was your favorite from the conference?
