- set up experiment with spinach seeds and our simulated ocean water, write predictions in science journal
will our control seeds germinate?
will seeds that are soaked for one week survive and germinate?
how about 2 weeks? 3 weeks? a month?
- use PBS lesson plan "Darwin's Great Voyage of Discovery", which includes a world map handout along with excerpts from The Voyage of the Beagle, to actually plot latitude and longitude points along Darwin's voyage from England to the Galapagos Islands
Friday, September 28
- finish mapping Darwin latitude/longitude project
- plant our spinach control seeds and the seeds which have soaked in "ocean" water for one week; make predictions; discuss Punic Wars and how Rome salted the ground after defeating Carthage so that no crops could grow there and thus Carthage could not be rebuilt
- conduct NEED science experiment "Exploring Heat 7" using thermometers, clear plastic cups, water, and sand
- read A Nest is Noisy by Dianna Hutts Aston
- discuss how the results of "Exploring Heat 7" connect with the nest building activity of the ovenbird (South America)
- do "Branch Weaving" art project from Good Earth Art by MaryAnn Kohl, page 130
- read weaver bird (Africa) and satin bowerbird (Australia) information from Bird Egg Feather Nest by Maryjo Koch
