Biology comes from the Greek word for life, bis, and the Greek word for thought or reasoning, logos. It denotes the science that studies life, the properties and processes that sustain life, the evolutionary history of life, and particular living organisms. It is a science of enormous diversity, breadth, and heterogeneity unified only by the conceptual framework provided by the theory of evolution. Indeed, as famously noted in by the Russian evolutionary geneticist Theodosius Dobzhansky — , “Nothing in biology makes sense except in the light of evolution”—a quote now replicated in so many university-level textbooks that it is almost a dictum in modern biology. One reason for the diversity of biology comes from the staggering diversity of organisms that can be considered living. These range from viruses, bacteria, and fungi to plants and animals, including humans. Another reason is that life can be studied on various levels in a hierarchy that ranges from the organic-macromolecular level to genes, cells, tissues, organs, and entire organisms. Furthermore, organisms interact in, and can be organized into, families, communities, societies, species, populations, biomes or biota, and perhaps even the global systems as in the controversial Gaia hypothesis, which postulates that the earth itself is a living organism. To a large extent, biological subdisciplines are organized around each of these levels of activity or organization.

References Generic Radiometric Dating The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth. The equation is the one which describes radioactive decay: The variables in the equation are: Pnow – The quantity of the parent isotope that remains now.

No reproduction may be made without prior approval from the author Dr. Relative Dating of Geologic Cross-Sections: Cliffs, road cuts, and non-vegetated landscapes allow us glimpses into geology which is often hidden from view. Cliffs and road cuts are “side views” or “geologic cross-sections” of the topography which show the relative positions of various rock layers and structures at a given spot.

Applying the principles of relative dating to these rock exposures also called “outcrops” , we can reconstruct the sequence of events that created the geologic features which we see. Events can be the deposition of a sedimentary layer, the eruption of a lava flow, the intrusion of magma to form a batholith, a fault break in the rock that shifts one side relative to the other side and causes an earthquake , a fold that bends and distorts rock layers, or any number of other geologic processes.

General Geology Name: General Geology Lab #7: Geologic Time & Relative Dating. Purpose: To use relative dating techniques to interpret geological cross sections. Procedure: Today we will be interpreting geologic history from geologic ic history is a .

This course is being removed July 1st. There is an updated Biology course available. You could consider switching over when you get to the end of a quarter. If you are having trouble with files and videos in this course and want to switch as soon as possible, you could switch at the end of a main unit. Please review the FAQs and contact us if you find a problem.

Middle school biology and chemistry Recommended: Students will learn through texts, videos, online interactives and through hands-on and virtual lab investigations. You will not be using those. Just follow the directions in the course below as to what materials to use each day. I believe in a literal six-day creation of the world by our holy, loving, almighty, creative God. This will be discussed in the beginning of the course to give the framework for how evolution will be approached.

Natural selection is taught as it corresponds with Biblical truth but not beyond that. Students will gain some understanding of secular evolutionary thought and come away strengthened in their faith.

Does it require more or less effort to push a loaded wheelbarrow over hard level ground than to turn around and pull it? What about when the ground is soft? Surely the clear lens would let the light through rather than casting a shadow? At constant velocity, is this a real effect? If so, wouldn’t it be felt on any “moving” surface you walk on, such as a train or plane — or even Earth?

Just as Sherlock Holmes used his power of observation to decipher the clues to a suspect’s past actions, we will let the blemishes and behaviors of the rocks tell us their past story. Am I getting too carried away here? Remember that relative dating involves determining “which came first” rather than “exactly when did this happen.

Filed under Pagadian City The Philippines, being a country archipelago of islands and seas, have naturally wonderful beaches, some of which are famous the world over. Beaches like Puerto Galera, Boracay, and the various beaches in Cebu rake in tourists from around the world all year round because of their pristine and cool blue waters and fine, white-sand shores. However, if one will just look around more, they will find that there are other less-known but equally beautiful beach spots in other parts of the Philippines.

Question assignment could be designed to go along with field trips. In addition, there is a virtual mapping project. Radioactive dating game through – students.

Radiometric dating Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts. Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old. However, research by creationists has revealed a large number of problems with radiometric dating. In some cases such as Carbon dating , radioactive dating actually gives strong evidence for a young Earth , while other methods such as K-Ar dating and Isochron dating are based on faulty assumptions and are so unreliable as to be useless.

Carbon dating Main Article: Carbon dating Carbon dating is a radiometric dating technique used to deduce the approximate age of organic remains by measuring the quantity of the isotope 14C in the sample and comparing it with the current atmospheric level. The usual isotope of carbon found in living organisms, 12C, is stable, while 14C is not stable.

Scientific measurements such as radiometric dating use the natural radioactivity of certain elements found in rocks to help determine their age. Scientists also use direct evidence from observations of the rock layers themselves to help determine the relative age of rock layers. Specific rock formations are indicative of a particular type of environment existing when the rock was being formed.

This new Java applet based version is more inquiry-based than the original version and contains tools so instructors can assess student learning. After you complete Virtual Earthquake, check out the Geology Labs On-Line home page for the latest information about project activities.

Activities about age dating, river discharge and river flooding are available. The instrument recording the seismic waves is called a seismograph and the recording is a seismogram. The point of origin of an earthquake is called its focus and the point on the earth’s surface directly above the focus is the epicenter.
