7.2: Changes to Earth 3 Dimensions & Progressions

Unit 3

●​ Many trace fossils have been found in Emery County. ●​ LIttle Cottonwood Canyon and Big Cottonwood Canyon have very different rock layers, even though they are not far from each other. ●​ The rock layers in the mouth of Parley’s Canyon are curved. ●​ In Monument Valley, the buttes have distinct rock layers. ●​ Trilobite fossils are found throughout Utah, sometimes on the surface, and sometimes in deep rock layers. END OF UNIT COMPETENCY WITH LANGUAGE SUPPORTS ●​ I can make an argument using evidence that the geologic time scale shows the age and history of Earth. ○​ Language Supports: ■​ CER Sentence Frames ■​ Connector to link clauses (as a result of, therefore, when we see, to be more precise, however, on the other hand) ■​ Diagrams, models, data (in the data we see, in this diagram we can see that, our model shows that)

DIFFERENTIATION IN ACTION

●​ Law of Superposition Newsela article ●​ How can you tell a rock’s age? Newsela article ●​ Dating fossils in rocks gives us a timeline of human evolution Newsela article ●​ How index fossils help to define geologic time Newsela article ●​ Students could pick a time in the geologic timeline to research and then write a narrative story about an organism or plant that lived in that time period and what everyday life might have been like.

ELA CONNECTIONS ●​ RST.6-8.1 Cite specific textual evidence to support analysis of science and technical texts. ●​ RST.6-8.7 Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table). ●​ RST.6-8.9 Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.
