We've been doing a brief filler unit (1/3 of the students are away at camp this week) revolving around "An Inconvenient Truth." There is certainly a lot there to draw students in, but I have to say that it is a little sad when sixth graders are finding errors in the book.
Student: This book lies.
Teacher A: Oh?
S: Yeah. See here where they say this [difference between two glacier photos] is 15 years? The photos are from 1978 and 2006, so that's almost twice that.
TA: ...You're right. They're 28 years apart. I don't know what to tell you.
