Description
“Digital video globes allow users to view and explore dynamic digital images of the Earth, other planets and space. NASA's "Dynamic Planet" exhibit is used extensively to help students and the public understand how NASA satellites contribute to a better understanding of our home planet, solar system, and the universe.

A new touch screen interface, called the NASA Science Explorer, drives the spherical display, allowing users full control over the content while learning about a wide range of remote sensing data. It can also be used on a flat screen if you don’t have a spherical display system.  NASA Science Explorer is freely available.”

Tips for Cooperative Learning Groups
Suggested by
Laura Gerson and Steve Lander
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 is always "leader" - who is supposed to keep the group on task.  The kids seem to turn this one into a joke.  Does anyone have a "real" 4th role they could suggest?  Thanks!
The 4th role is the experimenter (who does the activity with the assistance of any of the others) - carries out the procedure and therefore clearly understands the problem and directions. The materials manager also can enlist the aid of others to obtain, distribute and return materials.”


Computer Tips

VLC and Keepvid
Suggested by
John-Henry Cottrel
Description
Use VLC player to play the video (the best media player for videos as it plays absolutely everything and can also be saved and played from on your thumb drive) plus it’s free.
Then:
1 - Find your temp cache on your computer for your internet browser (as the video has already been temporarily downloaded on your computer)
OR
2 - Use Keepvid to download: 
http://keepvid.com/  paste in URL and it downloads it (though this has limitations whereas you can keep a lot more things if you can find your temp cache)
Play through VLC”


Demos

Site Name
Liquefaction Demo
Suggested by
Eric Fermann
Description
Play this liquefaction video: http://www.youtube.com/watch?v=5yMYxwtvIQE
Then:
I've done liquefaction as a (spur of the moment) demo before.  At the time, I paid no attention about the sand/silt/etc mixture.  In fact, I just dumped some soil from the back of the room (it was sitting there for a while and I was sure I wasn't going to need it again) into a beaker, mixed some water until it was "wet, but not runny".  I got out one of those pre-fabricated shake tables in one of our closets.  I stuck a very short piece of 1/4" rebar on top and a pencil part way in to the wet soil and started "earthquaking".  It didn't take much effort at all to have the rebar sink and have the pencil partially sink. 

Having thought about this now, I suppose I should have considered the make-up of the sand/silt/etc mixture, but it worked just fine with relatively some wet soil. 

In terms of a student research project...
Perhaps a fun experiment would be to create several varieties of "soil" by combining different amounts of sand/silt/etc and quantify the amount of liquefaction based on the amount and ferocity of shaking.  Then, go get some "backyard" soil, dry it out, sieve it, and try to determine how bad the liquefaction potential could be for the "backyard"
