Type: Informational Material

Overview:

The teacher will present an informational text from the website, ReadWorks. Students will interact with this non-fiction text by annotating the text digitally. This article will explain how the moon creates tides on Earth by exerting the force of gravity on Earth's oceans, even though the two celestial objects are not in contact. Students could use this informational material to construct their own argument explaining how fields exist between objects exerting forces on each other. 

Content Standard(s):
English Language Arts
ELA2015 (2015)
Grade: 8
19 ) By the end of the year, read and comprehend literary nonfiction at the high end of the Grades 6-8 text complexity band independently and proficiently. [RI.8.10]

Science
SC2015 (2015)
Grade: 8
Physical Science
12 ) Construct an argument from evidence explaining that fields exist between objects exerting forces on each other (e.g., interactions of magnets, electrically charged strips of tape, electrically charged pith balls, gravitational pull of the moon creating tides) even when the objects are not in contact.


NAEP Framework
NAEP Statement::
P12.22: Gravitation is a universal attractive force that each mass exerts on any other mass. The strength of the gravitational force between two masses is proportional to the masses and inversely proportional to the square of the distance between them.

NAEP Statement::
P12.23: Electric force is a universal force that exists between any two charged objects. Opposite charges attract while like charges repel. The strength of the electric force is proportional to the magnitudes of the charges and inversely proportional to the square of the distance between them. Between any two charged particles, the electric force is vastly greater than the gravitational force.

NAEP Statement::
P8.15a: Some forces between objects act when the objects are in direct contact or when they are not touching.

NAEP Statement::
P8.15b: Magnetic, electrical, and gravitational forces can act at a distance.


Unpacked Content
Scientific And Engineering Practices:
Engaging in Argument from Evidence
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Motion and Stability: Forces and Interactions
Evidence Of Student Attainment:
Students:
  • Construct an argument using evidence that fields exist between objects that are exerting forces on each other even when they are not in contact.
Teacher Vocabulary:
  • Argument
  • Evidence
  • Field
  • Forces
  • Distance
  • Exert
  • Contact
Knowledge:
Students know:
  • Two interacting objects can exert forces on each other even though the two interacting objects are not in contact with each other.
  • Fields exist between objects exerting forces on each other even though the two interacting objects are not in contact with each other. The existing fields may be electric, magnetic, or gravitational.
Skills:
Students are able to:
  • Articulate a statement that relates a given phenomenon to a scientific idea, including the idea that objects can interact at a distance.
  • Identify and use multiple valid and reliable sources of evidence to construct an explanation that fields exist between objects exerting forces on each other even when the objects are not in contact.
  • Use reasoning to connect the evidence and support an explanation that fields exist between objects exerting forces on each other even when the objects are not in contact.
Understanding:
Students understand that:
  • Fields exist between objects exerting forces on each other even when the objects are not in contact.

Comments

ReadWorks is a website that provides K-12 teachers with free literacy resources (About ReadWorks). ReadWorks has literary and informational texts on a variety of subjects and reading skills. You may narrow your search using grade level or Lexile level, making this website a wonderful tool for differentiation. Students will complete their work digitally, and you will provide their score and feedback digitally. This makes it easy to go paperless for this activity.

Prior to implementing this activity, you will need to sign up for an Educator Account on ReadWorks. After setting up an account, create a class from the Class Admin tab, this will provide you with a Class Code to give to students. Next, use the Find Content tab to search for the informational article that will be used during this activity, "Tides." After navigating to the article, click on the blue Assign button to assign it to your class.

Each student will need access to a digital device, such as a tablet or laptop. The first time students enter the website they will need to enter the Class Code that is listed on your Class Admin page. Alternatively, you can print the article for students, if digital devices are not available.
