This lesson isn't completely finished (I'm planning on using it for next week), but I thought some of you might find it useful to add onto or switch around to fit what you want to do. I cobbled this together from some things I might have found here or other corners of the internets.

The powerpoint first shows the planets and says a little something about each of them. After showing this part, you can have them label the planets on the worksheet.

Then, go through the rest of the powerpoint. Explain Roman gods, how they had gods for different things, etc. Then there's a slide for each planet and why they're named after the Roman gods that they are.

Putting this together was interesting for me, since I didn't know the meaning behind some of the planet's names...hopefully it's interesting for the kids too!

You sir are a master cobbler.  This **** works! :-X

I added the names of the planets in Korean and had the students compare the names. There's also some stuff about my speaking test I'm giving next week so that can be deleted.

Thanks!  This presentation was a big help.  I went on and added Pluto.  Even though it's not a planet anymore, I figured the mythology connection was worth mentioning.  I also added a couple of slides concerning Rome just for reference for my students.  I went on and added slides for the days of the week, since most of our days are named after astrological bodies.  For the days not named after these, I added slides with information of the Norse gods which they are named after, in addition to a slide referencing exactly what a Norse person is/was. On each slide for the days of the week, I have added the Korean name for the day as well as the Japanese name.  Students were interested to see that many of the days are named after the same thing in all three cultures.  All Japanese and Korean days are named for the same concept and students were all able to identify the kanji (hanja) used to name the Japanese days.
