Fossils form through a number of ways, but almost exclusively they form in sedimentary rock. This particular fossil is a mold and cast fossil that will only form in sedimentary rocks. As time passed and the land masses moved the rock layers that contained the trilobite must have been uplifted to form the mountain. Finally, through weathering and erosion, the fossil was exposed to be seen. The ultimate point is that the environment must have changed from a seabed to a mountain. Interactive Rock Cycle Annenberg Media produced a site with interactive rock cycle and classification information. The site ends with a printable assessment about the rock cycle that would be a great follow up assignment after the rock cycle lesson. To learn more, go to http: Gore from the Department of Geology , Georgia Perimeter College has a site with relative age dating information and instructions about ordering rock strata.
Mineralogy As a discipline, mineralogy has had close historical ties with geology. Minerals as basic constituents of rocks and ore deposits are obviously an integral aspect of geology. The problems and techniques of mineralogy, however, are distinct in many respects from those of the rest of geology, with the result that mineralogy has grown to be a large, complex discipline in itself.
fossils the same way a paleontologist would, by studying an outcrop. This way, the student learns about relationships between fossils and their environment, rather than just learning how to classify fossils one-by-one. It also illustrates how geologists use fossils to determine the relative age of different rock units.
At the same time, it should reveal an example of pseudoscience which should be part of any effort to improve science literacy and critical thinking. Students are taken through a combination of some background information and interactive experiences, and checked frequently by questions to confirm understanding. The narrative includes concepts of isotopes, radioactive decay, half-life, mineral formation, age analyses, Fair Test questions , and isochrons.
The lesson can be used as a one-day team activity, individually in class, or as a self-teaching homework assignment. It is intended to either stand by itself, or to serve as a useful introduction to the very effective online interactive Virtual Age Dating Tutorial. Several independent lines of evidence confirm that the Earth is billions of years old.
A Fair Test analysis confirms that the Earth is billions of years old. Half-life is a fundamental property of radioactive material, enabling accurate age-dating. Methods exist for age-dating which are internally self-checking. Efforts to overturn a massive body of work must be equally compelling. Anything presented as scientific, yet clearly ignores the rules of science, is pseudoscience. Key to Worksheet 1 page color preferred 4. Natural Radioisotopes Sequenced, with half-lives of a million years or more.

Evidence of Evolution Worksheets The evidence of evolution worksheet set is a series of diagrams and short activities to illustrate each of the major types of discoveries that support evolutionary theory. The first evidence of evolution students will identify involves changes in skull and foot fossils of different ancestors of the modern horse. The next pieces of evidence comparesembryos of different stages of chicken, human, fish, turtle, salamander, and rabbit.
The common bones within the limbs of humans, whales, crocodiles, cats, birds, and bats will be identified as an example of homologous structures. Finally, the animo acid sequence of a portion of the cytochrome C protein molecule will be compared for several different species. Overall, these worksheets should give students an excellent overview of the major pieces of evidence that used to develop the theory of evolution.
Evidence of evolution, fossil record, molecular homologies, homologous structures, analogous structures, embryology, vestigial structures. Available to teachers as part of the biology instructor resources subscription.

Flows, Cycles, and Conservation Objectives Students try to model radioactive decay by using the scientific thought process of creating a hypothesis, then testing it through inference. It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers. It is also useful in the mathematics classroom by the process of graphing the data.

Before the scientific era, people often made up imaginative stories to explain what they saw in the world. The scientific method changed that by requiring rigorous experimentation to test hypotheses and determine what is real. With the Theory of Evolution, people are back to making up imaginative stories. The primary advantage of complete metamorphosis is eliminating competition between the young and old. Larval insects and adult insects occupy very different ecological niches.
Whereas caterpillars are busy gorging themselves on leaves, completely disinterested in reproduction, butterflies are flitting from flower to flower in search of nectar and mates. Because larvas and adults do not compete with one another for space or resources, more of each can coexist relative to species in which the young and old live in the same places and eat the same things.
Ultimately, the impetus for many of life’s astounding transformations also explains insect metamorphosis: Nevertheless, “biologists have established a plausible narrative about the origin of insect metamorphosis, which they continue to revise as new information surfaces. In response to this unfavorable situation, some pro-nymphs gained a new talent: If such pro-nymphs emerged from their eggs before they reached the nymphal stage, they would have been able to continue feeding themselves in the outside world.
Over the generations, these infant insects may have remained in a protracted pro-nymphal stage for longer and longer periods of time, growing wormier all the while and specializing in diets that differed from those of their adult selves–consuming fruits and leaves, rather than nectar or other smaller insects. Eventually these prepubescent pro-nymphs became full-fledged larvae that resembled modern caterpillars. The underside of the wing has a brown pigment, which helps hide the resting blue morpho.
LEARNING FROM THE FOSSIL RECORD
The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
We are told that these methods are accurate to a few percent, and that there are many different methods.

My friends call me Ape Jaw Evan. Click here to read about me and other media myths, frauds, and lies. The Theory of Evolution is not a scientific law or a law of biology. Failure to meet only one challenge proves the law is wrong. This web page will prove that the Theory of Evolution fails many challenges, not simply one. The Theory of Evolution will never become a law of science because it is wrought with errors.
This is why it is called a theory, instead of a law. The process of natural selection is not an evolutionary process.
Dinosaurs disappeared about 65 million years ago. That corn cob found in an ancient Native American fire pit is 1, years old. How do scientists actually know these ages? Geologic age dating—assigning an age to materials—is an entire discipline of its own. In a way this field, called geochronology, is some of the purest detective work earth scientists do.

Potential of abundant, environmentally harmless energy technology , which already exists My strategy for manifesting that energy event for humanity’s and the planet’s benefit. I w as born in In that same year, I had my cultural and mystical awakenings. During my second year of college, I had my first existential crisis and a paranormal event changed my studies from science to business.
I s till held my energy dreams, however, and in , eight years after that first paranormal event, I had a second one that suddenly caused me to move up the coast from Los Angeles to Seattle, where I landed in the middle of what is arguably the greatest attempt yet made to bring alternative energy to the American marketplace. That effort was killed by the local electric industry , which saw our technology as a threat to its revenues and profits, and my wild ride began. The owner of the Seattle business left the state to rebuild his effort.
I followed him to Boston and soon became his partner. M y partner’s experiences in Seattle radicalized him. My use of “radical” intends to convey the original ” going to the root ” meaning. Radicals seek a fundamental understanding of events so they aim for the root and do not hack at branches , but more economically than politically in my partner’s instance. He would never see the energy industry the same way again after his radicalization also called ” awakening ” in Seattle, but he had more radicalization ahead of him.

In science, explanations are restricted to those that can be inferred from confirmable data—the results obtained through observations and experiments that can be substantiated by other scientists. Anything that can be observed or measured is amenable to scientific investigation. Explanations that cannot be based on empirical evidence are not a part of science. The history of life on earth is a fascinating subject that can be studied through observations made today, and these observations have led to compelling accounts of how organisms have changed over time.
The best available evidence suggests that life on earth began more than three and a half billion years ago. For more than two billion years after that, life was housed in the bodies of many kinds of tiny, single-celled organisms, some of which produced the oxygen that now makes up more than a fifth of the earth’s atmosphere.
