Lesson Set

In a discussion forum, pose the following questions:

Do you salt your food? Do you realize that by salting your food you are exposing

yourself to ions?

How alarmed should we be that we consume ions?

Techniques and activities

Day 1

Review what makes up the structure of atoms.

If students need to review online, they can go to:

strucrev1.shtml

Review what can change in number for atoms.

For example, changing proton number changes the type of atom. Changing neutron

number creates an atom of the same substance, but with a different molecular weight.

Changing the number of electrons changes the charge on the atom, which will

therefore be called an ion.

This could be a quick pop up quiz if in a synchronous session or a one question Google

form quiz if asynchronous.

Go over valence electrons and determine if an atom is more likely to gain electrons or

to lose them.

There should be a worksheet or a blank periodic table where students can write down

information about valence electrons and expected charges. Note: to be stable, each

atom wants 8 valence electrons unless it is a really small atom that is stable with 2

electrons in its valence shell. I will ask students if the atom we are examining is more

likely to gain one electron or lose 7 if it has 7 valence electrons. If it has 2 valence

electrons, is it more likely to gain 6 or lose 2? That type of questioning.

I don’t know how to make an interactive PowerPoint presentation, but I know it can be

done. I make a video of PPT slides where I ask questions, they get to answer with

multiple choice options. Instant feedback.

Use the image I made to have students explain why the ions are organized in a cubic

manner with alternating positive and negative ions.

This would probably have to be a short paper they turn in to a dropbox.
