It is good at this time to remind them that these letters represent fossils in a rock layer and that one fossil next to another within a rock layer implies no particular sequencing; they both are approximately the same age as that particular rock layer. Need some practice using the rules of relative dating to put rock layers in order from youngest to oldest? There is no technological component. It is recommended that students complete Procedure and answer the associated Interpretation Questions correctly before proceeding to. While you are there, feel free to post your own responses if you, too, are able to help out a classmate! In the second part of the activity, students progress to dating rock layers by sequencing fossils found in the different strata. Sequencing the rock layers will show the students how paleontologists use fossils to give relative dates to rock strata. Follow the procedures detailed on pp. Comments about Including the Science and Engineering Practice In this activity, students are tasked with constructing a timeline using fossils.

The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages. It's an experience they'll never forget well, maybe in time 5. Also consider permanently sealing each set in its plastic bag, if you have such a device. In the first part of the activity, students are asked to sequence cards by identifying and ordering overlapping letters found on the cards. Record all of your work in a word processing document. Minerals and Rock Minerals and Rock This topic looks at minerals and rocks and helps us to understand the different properties needed to identify them.

When you are satisfied with your selection, use the check answers button to check them. In what kinds of rocks might you find the fossils from this activity? Geologic Time Geologic Time In this topic we will learn about the beginnings of Earth. On an exam, I ask students to interpret a sequence of events for a different cross section than the one they saw in the activity. Moreover, we will focus in on the Greenhouse Effect and Global Warming and relate it to climate patterns. For example, ammonites lived in the Mesozoic era. Each card represents a particular rock layer with a collection of fossils that are found in that particular rock stratum. I will check that forum daily to respond.

Activity 8: Application of Relative Dating, Radiometric Dating, and Geologic Time Scale

Fossils and relative dating Fossils are important for working out the relative ages of sedimentary rocks. Correlation can involve matching an undated rock with a dated one at another location. In order to align this activity more closely to this practice, teachers should require students to explain and justify each step of their timeline. Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed. The major difficulty that students may encounter is the concept that extinction is forever. The sequence must be exactly in the order as written. In this activity, students begin a sequencing activity with familiar items - letters written on cards.

All of the fossils represented would be found in sedimentary rocks of marine origin. Consider using other items to replace the beans and popcorn. Oldest rock This rock layer is below all the others. We will place emphasis on the different types of volcanoes around the world and the potential hazards that they impose on mankind. This resource appears to be designed to build towards this crosscutting concept, though the resource developer has not explicitly stated so. Review Sheet · Practice Test Additional Resources Additional Resources The Physcial Setting: Earth Science can be a challanging course.

This rock layer would be younger as indicated by the appearance of new fossils in the rock stratum. By requiring students to provide an explanation for the individual steps in their timelines, teachers will ensure that students will be constructing explanations to complicated phenomena. Water and Climate Water and Climate In this topic we will focus on long term weather patterns and see how the changing Earth is responsible for creating unique areas of our planet. Locally, physical characteristics of rocks can be compared and correlated. The use of the fossil record to create this timeline closely mirrors the content of the Disciplinary Core Idea of Scale, Proportion and Quantity. Note: teachers may wish to assign a different code to the various fossil pieces.

Name three organisms represented that probably could not be used as index fossils and explain why. It may be useful to share with students after they have completed and answered the Interpretation Questions. A later event, such as a river cutting, may form a gap, but you can still connect the strata. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart. Students need to use principles of relative dating, such as superposition, cross-cutting relationships, inclusions, original horizontality, or original continuity. Aligned rubrics and scoring guidelines are not included but answers to the interpretive questions have been provided.

State the Law of Superposition and explain how this activity illustrates this law. If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. Moreover, this chapter will revisit sedimentary rocks and see how the sediments produced during weathering factor into the formation of the different rocks. · Practice Test Water and Climate Water and Climate In this topic we will focus on long term weather patterns and see how the changing Earth is responsible for creating unique areas of our planet. Drag and drop the text labels next to the layer you think is being described. To enhance this activity, have students match the fossil sketches to real fossils. Stratigraphic Section for Set B.

Plate Tectonics Plate Tectonics In this topic we will take a look at how the Theory of Plate Tectonics developed and provide concrete evidence that support the theory. The site editor may also be contacted with questions or comments about this Open Educational Resource. In a sequence, the oldest is at the bottom, the youngest is at the top. The cards in represent rock layers containing various fossils. The discovery of radioactivity and its application to dating rocks is perhaps one of the greatest scientific achievements affecting the Earth Sciences. Some fossils, called index fossils, are particularly useful in correlating rocks. The College of Earth and Mineral Sciences is committed to making its websites accessible to all users, and welcomes comments or suggestions on access improvements.
