http://www.nationalgeographic.com/ngyoungexplorer/0911/readstory.html This text is from the Nov/Dec 2009 issue of National Geographic's Young Explorer! magazine. The text is available online at this address. Students can look at it on a screen and even listen to it being read, or you can print it for classroom use, like I did in the lesson. If you print, make sure you print "landscape" for best results.
Here is a close reading lesson on a section of Gail Gibbons's book From Seed to Plant, suitable for 2nd or 3rd grades. This book is a text exemplar for these grades in the Core Academic Standards (Common Core).
