Course Understandings: Students will understand that:
● Forces have magnitude and direction and affect the motion of objects.
● Some forces between objects act when the objects are in direct contact and others, such as magnetic, electrical, and gravitational forces can act from a distance.
DESIRED RESULTS (Stage 1) - WHAT WE WANT STUDENT TO KNOW AND BE ABLE TO DO?
Established Goals
● Standard: Force
Forces have magnitude and direction and affect the motion of objects.
Benchmark:
6.2.2.2.1: Recognize that when the forces acting on an object are balanced, the object remains at rest or continues to move at a constant speed in a straight line, and that unbalanced forces cause a change in
the speed or direction of the motion of an object.
6.2.2.2.2: Identify the forces acting on an object and describe how the sum of the forces affects the motion of the object. For example: Forces acting on a book on a table or a car on the road.
6.2.2.2.3: Recognize that some forces between objects act when the objects are in direct contact and others, such as magnetic, electrical and gravitational forces can act from a distance.
6.2.2.2.4: Distinguish between mass and weight.
Transfer
Students will be able to independently use their learning to: (product, high order reasoning)
● Calculate the force of various objects with different masses and accelerations.
● Create/analyze situations with balanced and unbalanced forces and predict/confirm how motion changes.
● Communicate their understanding of Newton’s 3 laws of motion to an audience as the laws are applied to a real world object.
● Differentiate between forces that act in direct contact and at a distance.
Meaning
Unit Understanding(s):
Students will understand that:
● Everything in the universe is in motion.
● Force is a push or pull that can result in a change in motion.
● Newton’s three laws are used to determine the forces/motion of an object.
● Mass and weight are different measurements.

Essential Question(s):
Students will keep considering:
● Where do we see examples of the laws of motion in our daily lives?
● How does changing the force applied to objects with differing masses affect acceleration?
● Why does a body resist changes in its motion?
● Why is weight not a consistent universal measurement?
● How can forces act in direct contact and at a distance?
● How can a moving object experience balanced forces?

Acquisition
Knowledge - Students will:
Skills - Students will:
● Understand that some forces act when objects are in direct contact while other forces act at a distance.
● Observe and interpret what happens when an object comes in contact with an unbalanced force.
(6.2.2.2.3)
(6.2.2.2.1)
● Calculate the amount of force using F=MA formula
● Observe and interpret what happens when an objects comes in contact with a balanced force (6.2.2.2.1)
● Calculate net force of a scenario
● Conduct an investigation that supports a prediction of the motion of an object according to Newton’s first
● Determine if an object is experiencing balanced or an unbalanced force
law. (6.2.2.2.1)
● Model how balanced and unbalanced forces are combined in different ways affecting an object’s motion.
Reasoning - Students will:
(6.2.2.2.2)
● Explain how Newton’s first law allows you to predict motion. (6.2.2.2.1)
● Demonstrate forces that act at a distance: static electricity and magnetism. (6.2.2.2.3)
● Compare and contrast balanced and unbalanced forces with their effect on an object’s velocity.
● Identify situations when weight would change but mass would not. (6.2.2.2.4)
(6.2.2.2.2)
● Students will be able to measure mass with a triple beam balance (electronic balance) and weight with a
● Evaluate the effect of all forces acting on an object. (6.2.2.2.2)
scale.
● Compare and contrast forces between objects in direct contact and at a distance. (6.2.2.2.3)
● Distinguish between mass and weight and give examples. (6.2.2.2.4)
Common Misunderstandings
Students often think that…
● The location of an object can be described by stating its distance from a given point, ignoring direction
● An object’s speed is the same as its velocity
● If an object is accelerating, then the object is speeding up
● If an object is at rest, no forces are acting on the object
● Friction always hinders motion. Thus, you always want to eliminate friction
● A force is needed to keep an object moving with a constant speed
● Mass and weight are the same measurement
