Jigsaw Strategy

2

"Step 1: For a class of 36 students, form 12 groups of 3 students each. "

Step 2: Each student will be an expert of one law of motion.

Step 3: The experts disperse to “research meetings” with other experts. There will be 12 experts for each law. The 12 members will split depending on the availability of resources say, into 2 teams. Step 4: After research the experts disperse and go back to their group and present their knowledge.

Step 5: Collectively they (each group) will demonstrate their learning using a presentation, model, song, play, video, writing a book or any other style.

Group 1

1st law expert

2nd law expert

3rd law expert

SPS7. Students will determine relationships among force, mass, and motion.

a. Apply Newton’s three laws to everyday situations by explaining the following:

• Inertia • Relationship between force, mass and acceleration • Equal and opposite forces S8P5: Students will recognize characteristics of gravity,

electricity, and magnetism as major kinds of forces acting in nature. a. Recognize that every object exerts gravitational force on every other object and that the force exerted depends on how much mass the objects have and how far apart they are.

S8P3. Students will investigate relationship between force, mass, and the motion of objects.

a. Determine the relationship between velocity and acceleration. b. Demonstrate the effect of balanced and unbalanced forces on

an object in terms of gravity, inertia, and friction.

Newton's 3 laws of motion-Video

8

Newton’s first law of motionAn object in motion will stay in motion and an object at

rest will stay at rest unless acted upon by an unbalanced force."

""• An object will not change its motion unless a force

acts upon it."• All objects resist having their motion changed."• The tendency to resist a change in motion is called

inertia."• The more mass an object has, the greater its inertia.

Seatbelts?

1. Why do we have to wear seatbelts? "

2. Think of an alternative to seatbelts, describe how it would be designed and manufactured. "

3. What if I cannot wear a seatbelt due to medical reasons, how can I protect myself?

10

Newton’s second law of motion

The force of an object is equal to its mass times acceleration. (F=ma)

"• A net force changes the velocity of the object, and

causes it to accelerate. "• If an object is acted upon by a net force, the change

in velocity will be in the direction of the net force. "• The acceleration of an object depends on its mass.

The more mass an object has or the more inertia it has, the harder it is to accelerate.

11

Bridge crazy

Small cars, big trucks, bikes speeding down the bridge…

1. How do tension, compression, shear, torsion, and bending determine how a bridge is build?

2. What causes bridges to collapse?

3. How can the issue of bridge collapsing be prevented?

12

Newton’s third law of motion

For every action, there is an equal and opposite reaction."

"• When object exerts a force on a second object, the second object

exerts and equal force in the opposite direction on the first object.""

• The force exerted by the first object is the action force.""• The force exerted by the second object is the reaction force.

13

The sky is not the limit…Up! Up we go!

1. How does NASA apply the concept of “action and reaction?”

2. How else can the concept of Newton’s 3rd law of motion be applied in the society?

Answers should include specific examples, and illustrations.
