STAGE 1: IDENTIFY DESIRED RESULTS
Enduring Understandings
Students will understand that
momentum and impulse and how they relate to one another.
the idea of conservation of momentum and how to apply it to internal and external
forces.
how to apply momentum/impulse to elastic and inelastic collisions.
Essential Questions
What will happen if a 300-lb full back collides with a 180-lb defensive back?
What is the advantage of using gym shoes for running as opposed to dress shoes?
Which kind of vehicle are you safer in – and SUV or small Volkswagen during a
collision and why?
What would happen if you don’t wear your seat belt during an accident?
What is it like to be involved in or witness to an accident?
Knowledge and Skills
Students will know
momentum=mass x velocity
impulse
elastic & inelastic collisions
conservation of momentum internal/external forces.
Students will be able to
apply knowledge of momentum and impulse to collisions
distinguish between types of collisions
problem solve equations related to momentum and impulse.
Students will be familiar with
affect of momentum on ever day life (ex. gym shoes, sports, seat belts, hammering
nails, explosions).

STAGE 2: DETERMINE ACCEPTABLE EVIDENCE
What evidence will show that students understand?
Required Assessments (brief description)
Calculation of football scenario
regular and honors variation
Other Assessments (brief description)
Cart Explosion Lab: Student will use cart with a spring in between to create simulated
explosion. Student will calculate and show that each car leaves same momentum.
Seat Belt Movie Clips with Seat Belt Quiz: The seat belt problem shows how the force
drops dramatically as a crash adds a seat belt, air bag and other padding to increase the
stopping time.
Lab with 5 Momentum Balls (Newton’s Cradle): Students will answer questions

PLAN LEARNING EXPERIENCES AND INSTRUCTION
What sequence of teaching and learning experiences will equip students
to develop and demonstrate the desired understandings?
Learning Activities
W
How will you ensure that all students know where they are headed in the unit, why they are
headed there, and how they will be evaluated?
 Provide summary of unit and objectives
 Flow chart of equations
 Outline of activities
H
How will you hook students at the beginning of the unit?
 Demonstrations such as air bag videos, trampoline, egg thrown at sheet, etc
E
What events will help students experience and explore the big idea and questions in the unit?
How will you equip them with needed skills and knowledge?
 Air track labs
 Computer simulations
 Swinging Wonder/Newton’s Cradle
R
How will you cause students to reflect and rethink? How will you guide them in rehearsing,
revising, and refining their work?
 Ask one of the essential questions and have students reflect on it
E
How will you help students to exhibit and self-evaluate their growing skills, knowledge, and
understanding throughout the unit?
 Variety of practice problems especially on collisions
T
How will you tailor and otherwise personalize the learning plan to optimize the engagement and
effectiveness of ALL students, without compromising the goals of the unit?
 Hands on activities and labs
 Break problems into steps when needed
O
How will you organize and sequence the learning activities to optimize the engagement and
achievement of ALL students?
 Lead with phenomena through demonstration – momentum & impulse (or vice versa) –
conservation – collisions – elastic - inelastic

Student Performance Task
Unit : Mechanics – Momentum
Task: Explanation
Course: Regular Physics
Time Frame: ½ Period
Overarching Understanding:

Students will understand that various factors influence the relative motion of
objects.
Enduring Understanding:

Students will understand that how to apply momentum/impulse to elastic and
inelastic collisions.
