Type: Lesson/Unit Plan

Overview:

May the force be with you as you learn about using text features (like captions, bold print, subheadings, icons, and glossaries) to find facts about the force known as gravity! A big silly walrus will travel with you through this lesson.

Content Standard(s):
English Language Arts
ELA2015 (2015)
Grade: 3
14 ) Use text features and search tools (e.g., key words, sidebars, hyperlinks) to locate information relevant to a given topic efficiently. [RI.3.5]


Alabama Alternate Achievement Standards
AAS Standard:
ELA.AAS.3.14- Use text features (e.g., title, illustrations, glossary, table of contents, imbedded digital tools) to locate information.


Science
SC2015 (2015)
Grade: 3
1 ) Plan and carry out an experiment to determine the effects of balanced and unbalanced forces on the motion of an object using one variable at a time, including number, size, direction, speed, position, friction, or air resistance (e.g., balanced forces pushing from both sides on an object, such as a box, producing no motion; unbalanced force on one side of an object, such as a ball, producing motion), and communicate these findings graphically.


NAEP Framework
NAEP Statement::
P4.13: An object is in motion when its position is changing. The speed of an object is defined by how far it travels divided by the amount of time it took to travel that far.

NAEP Statement::
P4.14: The motion of objects can be changed by pushing or pulling. The size of the change is related to the size of the force (push or pull) and the weight (mass) of the object on which the force is exerted. When an object does not move in response to a push or a pull, it is because another push or pull (friction) is being applied by the environment.


Unpacked Content
Scientific And Engineering Practices:
Planning and Carrying out Investigations
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Motion and Stability: Forces and Interactions
Evidence Of Student Attainment:
Students:
  • Planned an experiment to determine the effects of balanced and unbalanced forces on the motion of an object using one variable at a time.
  • Carried out an experiment to determine the effects of balanced and unbalanced forces on the motion of an object using one variable at a time.
  • Collected data from experiment to serve as the basis of evidence for how balanced and unbalanced forces on an object determines an object's motion.
  • Communicated evidence and findings from experiment graphically.
Teacher Vocabulary:
  • Experiment
  • Variable
  • Motion
  • Force (push and pull)
  • Balanced forces
  • Unbalanced forces
  • Cause and effect
  • Number
  • Size
  • Direction
  • Position
  • Friction
  • Air resistance
  • Communicate
  • Graphically
  • Net force
  • Sum
Knowledge:
Students know:
  • Each force acts on one particular object and has both strength and direction.
  • An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object.
  • Forces that do not sum to zero can cause changes in the object's speed or direction of motion.
  • Objects in contact exert forces on each other.
Skills:
Students are able to:
  • Collaboratively plan an experiment to determine the effects of balanced and unbalanced forces on the motion of an object using one variable at a time.
  • Carry out an experiment to determine the effects of balanced and unbalanced forces on the motion of an object using one variable at a time.
  • Collect and record data from experiment.
  • Describe how the investigation plan addresses the purpose of the investigation.
  • Communicate findings graphically.
Understanding:
Students understand that:
  • Cause and effect relationships provide evidence when investigating balanced and unbalanced forces.
