The site also features an interesting Summary Map that illustrates several aspects of plate tectonics. Menu choices near the top allow you to chose what appears on the map.
Another interactive map allows you to view the position of the continents at various times during the past 600 mya. CLICK HERE to see it. To view a list of everything else the site has to offer, CLICK HERE.

The video focuses on geologic clues that led to acceptance of the theory that an asteroid impact killed of the dinosaurs. I ordered the video and plan to use it after my students learn how geologists interpret rock layers (superposition, cross-cutting, inclusions, etc.)
The HHMI site also provides several classroom ready resources to complement the video, including a quiz, as well as teacher guidelines and student handouts for several activities. To access those, CLICK HERE.

The video was featured as the July 23, 2012 "Astronomy Picture of the Day". Video Credit and Copyright: Tom A. Warner, ZTResearch, www.weathervideoHD.TV
Tom's camera was able to take 7,207 frames per second (actual time is shown at the bottom of the video). The 33-second video represents about .12 seconds of real time.
See if students can identify cities in your area. Initially, I was confused by the large area of lights in western North Dakota - until I realized there were due to activity in the Bakken Oil Fields. In most cases more light means more people. Challenge students to identify the Earth Science factors that draw people to specific areas (rivers, lakes and other water resources, harbors, soil, warm sunny climates, transportation/travel routes, mineral resources, etc.).
In the long history of mankind geology, hydrology, and meteorology have played important roles in the development of communities and cultures. An important aspect of every culture is the story of how that group of people adapted to their environment - how they figured out how to feed themselves, build shelters, clothe themselves, make weapons, even how they developed values and beliefs, etc.

Another great source is the animation provided by The New York Times, which explains and shows the sequence of events that caused New Orleans to flood in 2005. It is very impressive! CLICK HERE to see it. The animation created by graphic artist Dan Swenson and researched by Bob Marshall.
In fact 2011 was the deadliest tornado year in decades. How does it compare to other years in the past several decades? This week's resource is an interactive map that allows you to find out. CLICK HERE to view the interactive, which is provided by The New York Times. You can select any year on the scroll bar above the map (beneath bar graph) to look at a certain year, or you can let run (and pause it).
Also, The NY Times also has a page that features before and after aerial photos of the Joplin, Missouri tornado. CLCICK HERE to see that. Below those photos you will find a link to street-level before and after photos - pretty impressive!
Here is a link to NOAA's 2012 Severe Weather Summaries. Choose "large hail", "wind damage", or "tornadoes" at the top of the map to see where these different types of severe weather happened.
