Impact of the Honshu Quake

Description
Here are some of the truly incredible things that happened during the great Tohoku Quake near Honshu, Japan on 3/11/2011:
  • The northeastern shore of the island near the epicenter moved eastward more than 4m during the quake!  The western part of the island moved eastward by somewhat less than a meter....So northern Japan is now some 3+m wider than it was prior to the quake! (turn on the Japan-slip overlay in the file I sent).  I'm assuming that there was significant compressional stress built up in the island, and it expanded eastward as that stress was released during the quake.
  • The motion along the boundary between the subducted Pacific Plate and the overriding Okhotsk Plate* on was on the order of 24m at the epicenter!  (turn on the Japan-mainshock-slip overlay in the file I sent).  Apparently almost all of the motion was accommodated by the overriding plate moving eastward and up, while the Pacific Plate hardly moved. * The Okhotsk Plate is part of the larger North American Plate.
  • The upward movement of the plate raised the level of the seafloor just west of the trench an astounding 4.5+m, and created a basin 2+m deep off the shore (turn on the Japan-uplift-and-subsidence overlay in the file I sent).  The subsidence of the seafloor lowered the island by about 1m along the shore there (which would have the effect of moving the shoreline inland, but not the rocks under it).  I don't know this for a fact, but it seems like a 5m rise in the seafloor and a simultaneous lowering of the coastline would have added significantly to the damage caused by the tsunami.

Review Earth Science
Suggested by
Chris Sheehan
Description
Students can take 15 different online diagnostic tests to see which earth science topic(s) they are weak in.  Tests are composed of old regents’ questions and range from 10-30 questions.  Students receive a certificate of completion upon scoring an 80% or higher.  If a student is unable to pass the exam they know they need to study more on that particular topic.”

Description
“Animations in geography, particularly in physical geography, can help you to understand the complex processes that take place at or close to the surface of the earth. The animated diagrams and maps speed up time, giving you the opportunity to see and understand the long term changes that take place at or near the surface of the Earth. Many of the animations are also interactive.”

Tips for Cooperative Learning Groups
Suggested by
Robbie Robinette
Description
“I often have kids work in groups of 4.  In our professional development we have been told about assigning roles for the kids during group work.  Which is great.  But I feel like there are only 3 "real" jobs... 
1. recorder - records the info
2. materials - gets the materials (sometimes this can be 2 people, but often not)
3. speaker - presents data to the class
The 4th role
, I would make the 4th person a Tech Officer to do any computer related work, like running ppts, showing graphics, etc. Thanks!

Demos

Site Name
Hand Warmers
Suggested by
Judy Foulke
Description
“Hand warmers are great for demonstrating exothermic reactions. I empty the iron filings into a plastic bag and seal it quickly, then open a corner and ask a student to use a temperature probe and find the temperature. Then we open the bag, expose the filings to air and shake the bag. Then we take a second temperature reading. You could also ask students to feel the outside of the bag at the beginning of your demo and then after you've exposed the filings to air.

Water vapor in the air acts as a catalyst; the iron filings rust or form iron oxide.

You could compare this to an endothermic reaction such as adding vinegar to baking soda. My students are usually perplexed by this. They associate vinegar and baking soda with "make a volcano" projects. Lava is hot, so they expect the vinegar/baking soda concoction to be hot, and are quite surprised when it's not.”
