For his leadership, Libby received the Nobel Prize in Chemistry in 1960.Virtual courseware developed for introductory-level, on-line geology labs is an interactive teaching/learning model that has an enormous pedagogical potential for making Web sites places where students learn by doing.Creationists frequently describe carbon being used to date rocks; in fact, it cannot be used in that way, as rocks do not accumulate carbon in the manner that living material does.Also, the relatively brief half-life of C remains that the machine used to measure isotopes, a mass spectrometer, cannot reliably detect this amount within its normal background error.
About the project The Virtual Courseware website has a free suite of activities for both the life science laboratory and Earth science field studies that can be used by students ranging from middle school to high school, or in the college classroom.
The author's experience with bringing these two virtual applications on-line suggests that there is a need for interactive geology labs on-line and that the approach will be received with enthusiasm by the educational community.
The widespread implementation and adoption of virtual courseware can bring meaningful educational content and interactivity for the geosciences that goes beyond multimedia on the World-Wide-Web.
en español The age of the Earth is 4.54 billion years (Ga or Gyr), a number which geologists have determined by several independent methods.
Because of the recycling of crustal rocks by plate tectonics, no direct material from the earliest Earth still exists.
