Standards & Objectives

Academic standards
Cite specific textual evidence to support analysis of science and technical texts.
Determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.
Distinguish among facts, reasoned judgment based on research findings, and speculation in a text.
Write informative/explanatory texts, including the narration of historical events, scientific procedures/ experiments, or technical processes.
Produce clear and coherent writing in which the development, organization, and style are appropriate to task, purpose, and audience.
Alignment of this item to academic standards is based on recommendations from content creators, resource curators, and visitors to this website. It is the responsibility of each educator to verify that the materials are appropriate for your content area, aligned to current academic standards, and will be beneficial to your specific students.
Essential and guiding questions: 

Text-Dependent Questions:

  • Analyze the author’s suggestion that the Earth is like a great big magnet. What evidence in the text supports his claim?
  • Investigate the idea that the earth’s magnetic field protects the earth like an invisible force field. Cite evidence from the text that the
  • Earth has need for the protection that the magnetic field provides.
  • Evaluate the likelihood that the earth’s magnetic field will one day reverse. Support your ideas from the text.
  • Compare and contrast the earth’s magnetic field with the magnetic field lines that are created when an electromagnet is made from an iron core coiled in copper wire and attached to a battery.
