Georgia S4P3

S4P3 is a Georgia science standard. These are the elements under it.

• S4P3.a

  Plan and carry out an investigation on the effects of balanced and unbalanced forces on an object and communicate the results.

• S4P3.b

  Construct an argument to support the claim that gravitational force affects the motion of an object.

• S4P3.c

  Ask questions to identify and explain the uses of simple machines (lever, pulley, wedge, inclined plane, wheel and axle, and screw) and how forces are changed w...

01

What Students Need to Do

Students identify the pushes and pulls acting on an object. They decide whether the forces cancel or cause a change in speed or direction. They support their claim with observations, measurements, or diagrams.

02

What Mastery Looks Like

Students can examine a situation, name the forces, and predict how the object will move. They can explain that balanced forces do not change motion, while unbalanced forces do.

03

Common Misconceptions

Students may think balanced forces mean no forces are present or that any moving object has unbalanced forces. They may also assume equal forces balance even when they act in the same direction.

How to Assess It

Exit ticket: A soccer ball rests on grass, then a player kicks it. Label each situation balanced or unbalanced and explain the motion.

1. 01

   Use toy cars, string, and spring scales to test equal and unequal pulls, then record whether each car moves.

2. 02

   Have students explain in writing why a book stays still on a table, naming and comparing the forces.

3. 03

   Play force sort with scenario cards, placing each under balanced or unbalanced and defending every choice with a motion prediction.

4. 04

   Analyze a playground swing, a tug-of-war, and a stopped bicycle to identify when forces change motion.

• S2P2

  Obtain, evaluate, and communicate information to explain the effect of a force (a push or a pull) in the movement of an object (changes in speed and direction).

• S8P3

  Obtain, evaluate, and communicate information about cause and effect relationships between force, mass, and the motion of objects.

• S8P3.b

  Construct an explanation using Newton's Laws of Motion to describe the effects of balanced and unbalanced forces on the motion of an object.
