Students commonly have the misconception that all rocks are the same and that minerals can be manufactured. All students identified the correct answer, going as far as mentioning specifically that minerals cannot be manufactured, and most mention the work we did in previous years. This tells me that we need not spend a lot of time going over rock cycle, and we can move on to the new concepts of uniformitarianism and geologic time. I start the lesson by presenting the following slide-show :. Slides 8, 10 and 11 have specific instructions for the students to Think-Pair-Share , allowing students to engage in a scientific conversation with their peers SP8. In this video you can see an example of the conversation being had during the pair portion of the TPS.

MI-6 - Fossils are used to determine the relative age of rock and understand the history of the earth. MI-7 - The geologic history of Michigan can be told in part by the fossil evidence found in sedimentary rocks. O Use fossiliferous outcrop data to locate areas of similar geologic age in Michigan. O Use fossils to identify the age of rocks. O Use information from the MI Fossil Poster and the Fossiliferous Outcrops of Michigan Map to identify fossils sieved from earth material and determine possible locations for where the Earth material might have been excavated.

Grade Levels: Grades Students in lower grades 4,5 will need additional support for activity 6. Activities 6. Lesson Purpose: In this lesson, students use the geologic time line containing the fossiliferous outcrops found in Michigan recorded by geologic age to find a pattern of sedimentary rock ages in the Lower Peninsula and eastern portion of the Upper Peninsula.

Students will sieve fossil-laden earth material collected in Michigan, identify the fossils in this sedimentary rock, use information provided from the MI Fossil Poster to learn about the age of the fossils and apply the technique of relative age dating of rock using fossil evidence. This lesson is an inquiry lesson that involves students in the application of geologic data that is used to map the location of similar age rock strata, recognize the pattern of sedimentary rock in Michigan and apply relative age dating of earth material using fossil evidence.

Activity Description:. Students share fossil-finding stories in small groups. Students look for patterns of similar aged fossil-laden rock in Michigan.

Background Information:. Fossils are the remains or traces of once living things, both plants and animals, that are preserved from the geologic past.

Relative Dating of Rock Layers

Fossils can be found in rocks, glacial ice, ancient tar pits and amber. Fossils are formed in several ways; Fossils can be the actual preservation of an animal, the preservation of the shape of the organism a mold or cast of the organism or trace fossils indications that an organism was once on Earth such as dinosaur tracks, trails left by animals, burrows of animals or coprolites fossilized feces of animals. Each organism is evidence of the life that existed during that geologic time period.

Only a small fraction of past life has been preserved as fossils. To become a fossil, organisms must be buried by sediment before they are eaten or body tissues decompose.

sorry, that has

Body parts of organisms that are hard shells, bones, and teeth are more likely to become a fossil in the rock record. Fossils are used to help determine the relative age of Earth materials. Log In. Already registered? Log in here for access.

In relative age dating, scientists study a material and compare it to other similar materials in order to establish a timeline. It is essentially a big sequence: This comes first, that comes next. Examples of index fossils include: Ammonites were common during the Mesozoic Era ( to 65 mya), They were not found after the Cretaceous period, as they went extinct during the K-T extinction (65 mya). Brachiopods (mollusk-like marine animals) appeared during the Cambrian ( to mya); some examples still survive. Graptolites (widespread colonial marine hemichordates) that lived from.
