Virtual dating geology answers
Currently, there are three activities on-line with an additional 8 in preparation.
Technical Considerations and System Requirements Much of Virtual River consists of Java applets and Java Script routines. It has been tested on Netscape Communicator 4.08 and 4.5 on both Windows and Mac as well as Microsoft Internet Explorer 4.0 SP 1 and 5.01 on Windows and Microsoft Internet Explorer 4.5 on the Mac.
Testing was done on Windows 98/NT and Mac OS 8.1 and 8.5 on the Power PC.
As you know, rivers eventually overflow their banks and flood. It also can be a very costly natural disaster causing loss of life and millions or even billions of dollars in property damage.
Being able to predict the frequency (Recurrence Interval) and likelihood (probability) of flooding as well as the magnitude of floods (maximum peak discharge) can be used by land use planners to help reduce the potential hazards.
If you are running Netscape on the Mac, you will have more success with Virtual River if you increase the Suggested Memory Size to 32000K or more.
This doesn't mean that computers and settings with less memory will not work, but having sufficient memory seems to be critical.Description: Geology Labs On-Line is a comprehensive project to develop Web-based lab activities that enhance the learning and teaching of Geology at the College and High School AP levels.These "Virtual" labs are interactive where students learn by "doing" and not just clicking and viewing.Each activity requires you to make careful observations and measurements, do simple calculations, and answer questions about your work.A "Certificate of Completion" will be available to you at the end of each activity.If this is your first experience with hydrology (the science of the Earth' surface water), complete the exercises in order.Most students can complete an exercise in about 1 to 1.5 hours.Once they are able to manipulate the cards into the correct sequence, they are asked to do a similar sequencing activity using fossil pictures printed on "rock layer" cards.Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.This work is supported in part by grants from the U. National Science Foundation and the California State University System.All opinions expressed are those of the authors and not necessarily those of the NSF or the CSU. Virtual River works best with Netscape Communicator 4.08 or higher on both Windows machines and Macs and Microsoft Internet Explorer 4.0 or higher on Windows machines and Microsoft Internet Explorer 4.5 or higher on Macs.
