Wed Mar 23, 2011 7:52 PM in Submarine Canyons, activities and Information
Hello, Several years ago I was on a NOAA cruse to the four northern most Submarine Canyons off the East cost of the US. The ship was the NOAA Ron Brown. Besides investigating the flora and fauna, and extensive set surveys were done in order to estableis some accurate maps. Has anyone seen these maps? Also I would appreciate any material on submarine canyons. Regardless of age.

MARZANO? As a guide? Did you actually read through this book? His examples are for first year teachers, and that is being kind to him. He taught very little (if at all himself). He uses examples form other people's specific research as if it can be applied across all socio- economic learning groups and situations. I think you should read the reviews on this book (review by experienced teachers) no...

S O M E T I M E S .....OLD Labs are Better! Hi, I have a very special lab originally created by Caleb Wroe Wolf (1908-1980) from a 1959 Earch Sceince Lab Activity workbook. [I know, it's O L D, but so am I]. The Lab activity is on Ocean Surface Currents. It consists of two pages of questions. The questions are related to two maps. One MAP shows the earth's surface Ocean Currents (and Iceb...

5 Variable Biochemical change in the Environment
ON the surface it appears to be about the ripening and death of fruits and vegatables. However, I believe if one reads the article over a second time, and preforms the actual lab, yeu will realize that the articel can apply to many aspects of change in the environment related to why certain plants do not bloom or reproduce when they should, or die out when the environment they exist in goes under variouis stresses. 1st) A nice connections is made withe the four variables to plant physiological change. They are: a) Concentratins of atmospheric gasses - (This alone requires extensive study, and can be made into numerous scientific inquiries. b) Disease. Also diseases form other plants can place stress directly on a target plant sturess on a different plant that has shared symbiotic microbial connections, thus indirect affects. C) Temperature. (This is the only obvious variable) D) Plant hormones in lesser or more concentration. This of course can relate directly back

5 Classifications of Basic Chemical Entities
This interactive activity attempts to explain the periodic table from a HIstorical Perspective. I believe this is a little weak. In fact the only weak part of the activity. Why, a key element that can be applied in a major way across the major sciences namely Biology, PHysics, and chemistry, is OXYGEN. There is a great story line in its' discovery. Namely the co-discovery of Lavoisier and Priestly. And, how the story of HOW they discovered it. However, the aspects of two interactive videos, followed interwoven with superior pictures, with some shown on an interesting chemical activity are superiior, and interesting. Within this activity can be found mumerous expample of good science. Example, the predictiion of future elements my early scitentists is excellent. Further, there are good questions for review, as well as constant inquiry questions for reflection, a summery, and quiz at the end. Finally, I thought the Point and click Glossary at the end should be included in all of my lesso

5 Chemical Reasctions: The Initial Energy
This was an exeptional interactive inquiry. I believe it can be used in HIgn School for 9th grade Physical Science, and for 11th Grade basic Chemistry. The interactive graphs were colorful, easy to use, and expalined well. I especially liked the section that used Fe + CuCl2 yields FeCl2+Cu. NOt only can this formula be use throughout the lab activity (virtual Lab activity) it also shows one of the ways one can smelt Copper, which I do not think was mentioned. This is a great lab.
