Map Distortion

I hate liars.  Well, I mean... I don't hate them, hate them.  But I don't like when people lie to me.

Or when maps lie to me.

But, basically every map is telling at least a little lie.

Today we noticed that the earth is measured in degrees.  (We noticed this exact same thing last week.)  And the distance between the degrees differs depending on where you are.  If you're standing on the Equator, 1 degree is nearly 70 miles.  If you're standing on the North Pole, it's less than an inch.

And all those degrees at the north and south get stretched out, distorting most maps we look at.

To show what I meant, we watched a couple videos.  Feel free to check them out here:

Students can earn extra credit by reading and discussing this blog with an adult.  If you've done that, find a scrap of paper and write the phrase, "Maps are lying liars."  Then, students should have the adult they read the blog with sign the paper and turn it in tomorrow.  (They should also make sure their name, date, and class period is written on there somewhere.)
