What are some key examples of fossil evidence that support the theory of evolution? Why are fossils so rare, and why is it difficult to find an evolutionary trail of fossil species leading from a common ancestor? What questions remain unanswered by relying solely on the fossil record? The Lesson Part I: Have your class watch the Becoming a Fossil video and read the backgrounder. Discuss the following questions with your class: Why do most living things not leave fossils behind? How are fossils formed? How are fossils found?
This study has shed light on GIT illnesses related to the intestines and digestion, such as obesity, Irritable Bowel Syndrome and Diabetes, just to name a few. These findings … Continue reading"Curriculm Map" The Spider Silk Protein May Lead to Generation of Artificial Heart for Humans September 6, The biocompatibility, biodegradability and strength of spider silk are some of the properties that have excited researchers on the possibilities it provides.
This is a protein-based compound that does not cause any adverse allergic, immune or inflammatory reactions in humans.
However, another form of relative dating is the use of fossil succession: the principle that certain assemblages of fossils can be tracked in a stepwise fashion through geologic time.

The letter of the law is found in the Statutes and in the regulations as published in the Canada Gazette. Although once offered in paper format to all CFIA employees and new revision pages were distributed every 12 to 18 months so these versions would remain current with any new amendments, this service is no longer offered.
Instead, the most up-to-date version of the FDA and the FDR is found on the government Justice Department website see reference section of this chapter.
This is called the fossil record. By studying the fossil record, scientists have found that the Earth and its living things have gone through many changes in the past. Fossils have even taught us about the climate of the Earth during different times of Earth"s history.
Fossils over time Introduce students to fossils this is one approach; see below for an alternative approach: Brachiopods and trilobites were abundant from about to million years ago mya. Ammonite fossils were most abundant between and 65 mya died out when dinosaurs did. Dinosaur fossils must be older than 65 million years last non-avian dinosaurs went extinct then. Earliest whale and pre-whale fossils would be less than 55 million years old.
There are no known human fossils older than about 7 million years. As part of this, show the class an enlarged version of the chart:

Students shall demonstrate an understanding that science is a way of knowing. Explanations are based on observations, evidence, and testing B. Hypotheses must be testable C. Scientific knowledge must have peer review and verification before acceptance Standard Students shall design and safely conduct scientific inquiry Develop and explain the appropriate procedure, controls, and variables dependent and independent in scientific experimentation NS.

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.

April Koch April teaches high school science and holds a master"s degree in education. You may already know how to date a fossil with a rock. But did you know that we can also date a rock with a fossil? Watch this video to find out how we use index fossils to establish the relative ages of rocks. Review of Relative Dating In previous lessons, we talked about the Geologic Time Scale and how scientists use it to piece together the history of the earth.
We talked about relative dating of rocks and how scientists use stratigraphic succession to compare the ages of different rock layers. You should already understand that the lower rock strata are generally older than the strata found higher up in the rock. When a scientist finds a section of rock that has lots of different strata, he assumes that the bottom-most layer is the oldest, and the top-most layer is the youngest. But sometimes, a scientist finds a couple of rock outcrops that are separated by a wide distance.
One outcrop shows layers from one geologic time period, while the other outcrop represents a different time. What can a scientist do with these two outcrops?

C use the school"s technology and information systems in a wise and ethical manner. B know that scientific hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence. Hypotheses of durable explanatory power which have been tested over a wide variety of conditions are incorporated into theories; 2.
C know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers.
Living fossils, organisms previously known only through the fossil record and having no close living relatives, pose a grim threat to the evolutionary paradigm. Transitional Fossils Evolution predicts a fossil record bursting with transitional fossils.
