Earth Science

Quarter 2

McGraw Hill Module 18

Students use at least two examples (to construct, make and defend a claim) oral and written logical arguments. The examples: ● Include that the evolution of photosynthetic organisms led to a drastic change in Earth’s atmosphere and oceans in which the free oxygen produced caused worldwide deposition of iron oxide formations, increased weathering due to an oxidizing atmosphere and the evolution of animal life that depends on oxygen for respiration; and Identify causal links and feedback mechanisms between changes in the biosphere and changes in Earth’s other systems.

ELA CONNECTIONS

● Cite specifc textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account. ● Determine the central ideas or conclusions of a text; summarize complex concepts, processes, or information presented in a text by paraphrasing them in simpler but still accurate terms. ● Write arguments focused on discipline - specifc content. ● Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation. ● Make strategic use of digital media (e.g., textual, graphical, audio, visual, and interactive elements) in presentations to enhance understanding of fndings, reasoning, and evidence and to add interest.

MATH CONNECTIONS

● Reason abstractly and quantitatively. ● Model with mathematics.

● Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. ● Defne appropriate quantities for the purpose of descriptive modeling.
