ELA21.3.19

Determine the explicit or implied main idea and supporting details of a text.

UP:ELA21.3.19

Vocabulary

  • Explicit main idea
  • Implied main idea
  • Supporting details

Knowledge

Students know:
  • The main idea is the most important idea presented in the text.
  • Sometimes an author will clearly state the main idea, while other times an author will merely suggest the main idea.
  • The supporting details explain the main idea or provide more information about the main idea.

Skills

Students are able to:
  • Identify the main idea in of a text.
  • Determine if the main idea is explicitly stated or implies.
  • Identify the supporting details of a text.

Understanding

Students understand that:
  • Literary and informational texts have a main idea, or most important message, and supporting details, which provide more information about the main idea.
  • An author can choose to state the main idea in the text or provide clues to imply the main idea.
  • A text usually just has one main idea, but multiple supporting details.

SC15.3.3

Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).

UP:SC15.3.3

Vocabulary

  • Explore
  • Manipulate
  • Cause and Effect
  • Electrical Interactions
  • Magnetic Interactions
  • Magnet
  • Repel
  • Attract

Knowledge

Students know:
  • The size of the force can affect the electrical and magnetic interaction of two objects not in contact with one another.
  • The orientation of magnets can affect the magnetic interaction of two objects not in contact with one another.
  • The repulsion or attraction of magnets can affect the magnetic interaction of two objects not in contact with one another.
  • The presence of a magnet and the force the magnet exerts on other objects affects the magnetic force of two objects not in contact with one another.
  • The electrical charge of an object can affect the electrical force of two objects not in contact with one another.

Skills

Students are able to:
  • Explore electrical interactions between two objects not in contact with one another.
  • Explore magnetic interactions between two objects not in contact with one another.
  • Determine cause-and-effect relationships of electrical interactions between two objects not in contact with one another.
  • Determine cause-and-effect relationships of magnetic interactions not in contact with one another.

Understanding

Students understand that:
  • Cause and effect relationships are routinely identified, tested, and used to explain change.
  • Magnetic and electrical forces affect the way objects interact.

SC15.3.4

Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).*

UP:SC15.3.4

Vocabulary

  • Magnet
  • Properties
  • Engineering Design Process (Ask, Imagine, Plan, Create, Improve)
  • Attract
  • Repel
  • Forces

Knowledge

Students know:
  • Magnetic forces between a pair of objects do not require that the objects be in contact with each other.
  • The sizes of the forces in a magnetic situation depend on the properties of the objects, the distances apart, and their orientation relative to each other.

Skills

Students are able to:
  • Define a problem that can be solved with magnets.
  • Apply scientific ideas about magnets.
  • Solve a problem with scientific ideas about magnets through an engineering design project.

Understanding

Students understand that:
  • Scientific discoveries about the natural world, such as magnets, can often lead to new and improved technologies, which are developed through the engineering design process.
