Core Idea - Motion and Stability: Forces and Interactions

[3.PS.2.3] - Conduct an investigation to determine the nature of the forces between two magnets based on their orientations and distance relative to each other. Clarification Statement: Focus should be on forces produced by magnetic objects that are easily manipulated.

Predecessor Standards:

No Predecessor Standards found.

Successor Standards:

  • 8.PS.2.2
    Provide evidence that the change in an object’s speed depends on the sum of the forces on the object (the net force) and the mass of the object. Clarification Statement: Emphasis is on balanced (Newton’s first law) and unbalanced forces in a system, qualitative comparisons of forces, mass, and changes in speed (Newton’s second law) in one dimension. State Assessment Boundaries: State assessment will be limited to forces and changes in motion in one dimension in an inertial reference frame and to change in one variable at a time. The use of trigonometry is not expected in state assessment.

Same Level Standards:

  • RI.3.3
    Describe the relationship between a series of historical events, scientific ideas or concepts, mathematical ideas or concepts, or steps in technical procedures in a text, using language that pertains to time, sequence, and cause/effect.
  • W.3.2
    Write informative/explanatory texts to examine a topic and convey ideas and information clearly.
  • 3.MD.B.4
    Generate measurement data by measuring lengths of objects using rulers marked with halves and fourths of an inch. Record and show the data by making a line plot (dot plot), where the horizontal scale is marked off in appropriate units—whole numbers, halves, or fourths. (See Glossary for example.)
  • 3.PS.2.4
    Define a simple design problem that can be solved by using interactions between magnets.* Clarification Statement: Examples of problems could include constructing a latch to keep a door shut and creating a device to keep two moving objects from touching each other.
