The Columbia Encyclopedia, 6th ed. Over 12, known species are grouped in three classes: Annelids are found throughout the world, from deep ocean bottoms to high mountain glaciers. They live in protected habitats such as mud, sand, and rock crevices, and in and among other invertebrate animals, such as sponges. Many live in tubes they secrete around themselves.

Life Science: Dating the Fossil Record ActivityName Per.. You have received nine rock samples from a paleontologist in California. Your job is to arrange the samples in order from oldest to youngest according to their fossil content and to determine their relative ages using the process of relative dating.

You can copy the webpage into an editor, such as word or openoffice and modify it for your classroom needs. If you repost, be sure to share alike , which is how the page is licensed. All of my worksheets can probably be improved upon, and definitely make changes if needed to fit with your own class and schedule. This activity assumes students know the basic principles of evolution, it is more of an “end of the unit” activity than beginning.

You will need large poster paper to set up the record. I’ve used construction paper taped together if that’s what I have laying around. Students like to pick colors too. This project is more about the “process” than the final outcome. Give a brief description of the evolutionary changes that occured in the organism. During which time period did the fossils differentiate into two branches.

Explain how the chart illustrates both punctuated equlibrium and gradualism.

An Index to Creationist Claims

For example, rock layers show the sequence of geological events, and the presence and amount of radioactive elements in rocks make it possible to determine their ages. Analyses of rock formations and the fossil record are used to establish relative ages. In an undisturbed column of rock, the youngest rocks are at the top, and the oldest are at the bottom. Rock layers have sometimes been rearranged by tectonic forces; rearrangements can be seen or inferred, such as from inverted sequences of fossil types.

The rock record reveals that events on Earth can be catastrophic, occurring over hours to years, or gradual, occurring over thousands to millions of years.

Relative dating is done by observing fossils, as described above, and recording which fossil is younger, which is older. The discovery of means for absolute dating in the early s was a huge advance.

January Fossils provide a record of the history of life. Smith is known as the Father of English Geology. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.

Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating. These skeptics do not provide scientific evidence for their views. Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data. The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them:

Sunday, August 21, I teach a course on 1 Corinthians at the seminary, have used the commentaries you cite as textbooks, and have more familiarity with the literature generally than you do. Partaking in sexual immorality most certainly does have to do with paganism. It has to do, at least in part, with a return to the immoral lifestyles out of which they emerged, though Paul admits in the case of incest they are even outdoing the pagans in immorality.

Paul repeatedly warns Gentile converts in all his letters not to live as they once lived as Gentiles who did not know God. In 1 Thess 4, Gal 5, 1 Cor , 2 Cor 12, Romans 1, 6, 8, 13 , not to mention texts in Col 3 , Eph , and the Pastoral Epistles, Paul repeatedly states that if believers adopt again their old Gentile practices, especially sexually immoral practices, they will not inherit the kingdom of God.

In December , an earthquake centered in the Indian Ocean caused a tsunami that affected many of the nearby countries.

Planet Diary Geosphere Activity

So, how do we know how old a fossil is? There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

Fossils don’t tell the whole story, but they’re a great place to start reconstructing Earth’s past. In this Planet Diary activity, you’ll explore the fossil record. Directions.

Pollution resolution If I replace my old diesel car with a less polluting new petrol one, how long will it take for the reduced pollution of the new car to outweigh the increased pollution caused by the manufacture of the new car and the disposal of the old, assuming average usage? It seems such a waste of energy. I read that a supermarket won an award for its two-year-matured puddings. So, what happens over two years to bring out the flavour?

Where I live, I use five different bins and the collections are fortnightly. Unlike many people I observe, I squash things like aluminium cans and plastic milk bottles. It seems logical and reduces the volume of rubbish stored in the house — but does doing so help collection and recycling? At what point would something be attracted to someone or able to establish an orbit?

Continued 24 January How much lead was used in the manufacture of leaded petrol before it was banned, and where is that lead now? It doesn’t seem to cause them to lose their fur or hair, unlike humans. So why do humans have to be so careful and only drink clean water?

Paul Berry After building the product for Huffington Post, and owning the product and engineering groups at AOL after we were acquired, it was clear to me there was a huge gap between what the current CMS offering gave the world and what the world needed. Five years later we are at scale, moving the needle and doing to WordPress what Airbnb did to Craigslist.

Social and Centralized WordPress, Drupal, and the custom CMS solutions of the world are all independent, non-connected instances that each need to be updated individually. There are over 87 million instances of WordPress alone in the world, and each security upgrade, feature update, and every other single thing has to be updated for each site individually.

Getting into the Fossil Record In this interactive module students are introduced to fossils and the fossilization process by examining how fossils are formed .

Idahoan the present 30, 2. The group of “fossils” you will work with are ficticious animals. Each fossil on your sheet is marked with a time period. Cut out each fossil and make sure you include the time period marked below it. Arrange the fossils by age. On your data chart, place each fossil next to the period from which the fossil came from. The term “upper” means more recent and should be placed lower in the low.

The term “lower” means an earlier time period, fossils from a “lower” time period should be place toward the older time periods.
