Force and Motion

Move it! Move it!

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

How Does Force Affect Motion?

A force is a push or pull that can cause an object to:

Move

Stop

Change direction

Change speed

(Article by Gerald Darling)

How Does Force Affect Motion?

Did you:

Ask “I wonder what would happen if…”

Make a prediction

Experiment

Draw a conclusion

(Article by Gerald Darling)

How Does Force Affect Motion?

Opposite equal forces

• Gravity = Table

• Boy = Door

• ???

(Article by Gerald Darling)

First Law of Motion

An object at rest will remain at rest unless

acted on by an outside force.

An object in motion continues in motion with

the same speed and in the same direction unless

acted upon by an outside force.

First Law of Motion

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”

Ramps and Pathways

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 Betty Zan and Rosemary Geiken)

LET IT ROLL

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

(Article by Kathy Cabe Trundle and Mandy McCormick Smith)

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

Examples

Object/Activity

Change in Speed

Change in Direction

downNo, moves in straight line

A child stops the ball (pull)

Ball slows down

Arch down toward ground

A child catches the ball (pull)

Gravity/ air resistance

AN INQUIRY PRIMER

Define the different forms of inquiry

Begin a list of good open-ended inquiry questions (review all of the articles you have read thus)

(Article by Alan Colburn)

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!
