Friday, September 20

Morning

Afternoon

  • explain Glacier / Fjord / Iceberg

  • discuss how ancient glaciers affected our state geography, scraping much of Illinois flat; look at maps on pages 5, 6, and 7 of Illinois: A History in Pictures by Gerald Danzer

  • look at photographs of glaciers and icebergs from a classmate's trip to Alaska


15,500 years ago a vast volume of glacial meltwater, the Kankakee Torrent, raced down through Illinois. The ancient Ohio River was overwhelmed by the glacial outwash and forced to move course completely to its new location. The great ancient Ohio River valley remains, and is now occupied by the much smaller Cache River.

A great family field trip to follow up on this would be the Cache River State Natural Area.


In other news, everyone in our group started knitting little white kittens this week. So sweet!!!!

We also continued with our read aloud story, Abel's Island by William Steig, and our poem in Speech & Recitation, "The Kind Mousie" by Natalie Joan.
