Download Force and Motion

Overall Objectives
Define the concepts of force and motion
Develop scientific inquiry teaching skills
Implement investigative force and motion
activities in your classroom
Reflect on outcomes and use teaching methods
with other science concepts
How this is going to work
Part 1
Explore/play, read an article, outline what you
learned
Participate in webinar
Read more articles, conduct a survey and
begin learning about inquiry
How this is going to work
Part 2 – Face-to-face workshop
Part 3 – Implement in your classroom
Part 4 – Reflect and share via phone conference
(Article by Gerald Darling)
A force is a push or pull that can cause an object
to:
Move
Stop
Change direction
Change speed
(Article by Gerald Darling)
Did you:
Ask “I wonder what would happen if…”
Make a prediction
Experiment
Draw a conclusion
(Article by Gerald Darling)
Opposite equal forces

• Boy = Door

First Law of Motion
An object at rest will remain at
rest unless acted on by an
outside force.
First Law of Motion
An object in motion continues
in motion with the same speed
and in the same direction
unless acted upon by an
outside force.
Newton’s First Law
“Objects tend to keep on doing
whatever they’re doing (staying at
rest or staying in motion) unless
something else exerts a force on
them.”
From Stop Faking It! Force & Motion
by William C. Robertson PhD
Some science stuff
Speed – distance traveled/time traveled
(miles per hour or meters per second)
Velocity – speed + direction
(the ball is rolling 0.2 m/s toward Suzy)
Acceleration – a change in velocity
(a change in speed or a change direction or
a change in both)
One more thing
Mass is how much stuff
is in an object
Weight is the pull of
gravity on an object
Second Law of Motion
Acceleration happens when a force
acts on a mass. The greater the mass
(of the object being accelerated) the
greater the amount of force needed (to
accelerate the object).
Acceleration
Newton’s Second Law
Pushing or pulling an object causes
acceleration, a change in the speed or
direction or both.
An acceleration can be a slowdown OR a
speedup. The heavier the object, the more
force it takes to make that object speed up
or slow down.
Questions and Comments
Are there any concepts you would like to review?
Does any one want to share something they
discovered in their own play?
Before the face-to-face workshop:
Read “Ramps and Pathways” article
Read “Let it Roll” article
Take notes on what you have learned
Conduct a survey of your space
Read “An Inquiry Primer”
(Article by Betty Zan and Rosemary Geiken)
Outline the important components of teaching a
scientific investigation lesson on force and
motion
Outline some things you might like to try in your
classroom
(Article by Kathy Cabe Trundle and Mandy McCormick Smith)
Start a vocabulary list for yourself - this is not for
the children - this is to help your understanding
NOTE – you do not need to include terms like
“rotational inertia” unless you want to dig that
deep
Force and Motion Survey
Take a survey of your classroom and outside play
area and describe the “fantastic four” for 5 – 10
objects/activities and the forces acting on them
Start motion
Change in speed
Change in direction
Stop motion

(Article by Alan Colburn)
Define the different forms of inquiry
Begin a list of good open-ended inquiry
questions (review all of the articles you have
read thus)
Next Generation Science
Standards
PS2.A Forces and Motion/ PS2.B Types of Interaction
Pushes and pulls can have different strengths and
directions, and can change the speed or direction of its
motion or start or stop it.
PS2.C Stability & instability in physical systems
A change in motion of an object can depend on the
effects of multiple forces.
Happy Learning!
