I really found the map thing interesting, so here are some pictures for you all to look at.

It's impossible to impose a spherical image onto a flat plane. Hence there are about a dozen different ways to impose it. Some make the middle look normal and the poles big (the typical one where greenland is huge) other ones contort things differently. The only way to view the world correctly is with a globe.

But the bottom image is to scale while the top image was supposed to be used only for navigational purposes. We did talk about globes, but for a classroom wall, the top image is drastically distorted.

No image can be to scale if it's on a 2D plane. Okay I'm right about this but don't get mad okay.

The sizes of the continents are proportional, though. Compare that to the first map.

we learned about the different projections in our school in 6th grade. we learned about the inacuracies of that projection. I think it's fine to use those maps as long as you tell the students it's not scaled right. it's very nice to use it for geography and history lessons. I wouldn't want my kids thinking that's how the world actually looks though.

I had never learned about the different projections, nor had the majority of the audience there tonight.

Hence why I am so amazed.

I don't think that map would be appropiate for a geography lesson because the sizes are so far off. I certainly wouldn't want to try to explain to my first graders about that when I could just show them a correct map and have them learn it right the first time.

I'm not saying otherwise. I just wanted to let you know that some schools do teach it. and I learned about it and turned out alright.

katiek704 March 10 2006, 04:02:30 UTC

But most schools do NOT teach it.

I turned out fine not learning it.

Do I think that's okay, though?

No, not at all. It's sickening.

Also, it just occurred to me- I remember lots of facts about different things from middle and highschool and I beleive it was either Mr. Kolodgiez or Mr. Maxwell displaying maps with greenland and iceland in correct proportion. It was probably a side not but it struck me as interesting and I'm sure it didn't create and really response from teenagers, but, yeah, at least my grade was once in our lifetime taught the correct proportions of the two islands.

Now for a funny story petrockthief March 12 2006, 09:37:20 UTC

I don't have all the facts straight on this one but apparently someone in one of my brother's HIGHSCHOOL classes thought that Alaska resides just southwest of the continent
