1. Lead-in (5-10 minutes)

Students look at pictures and talk about what they know about them

• The teacher tells the students that they are going to read a text about the Newton’s Laws of Motion.

• The students brainstorm the topic (in groups). The teacher teaches basic information

Law 1. Newton's law of motion states that for every force there is an equal and opposite force. These forces are called action forces and reaction forces.

Law 2. Newton's law of motion states that objects at rest tend to stay at rest, and objects that are moving tend to continue moving. This tendency of objects to resist changes in motion is called inertia.

Law 3. Newton's law of motion states that when an unbalanced force is applied to an object the object accelerates. The amount of acceleration depends on the mass of the object and the amount of force applied to it. More force to an object results in greater acceleration. Increases in mass result in less acceleration.

2. Task 1: Predicting content (5-10 minutes)

Students match the above 3 Newton's Laws of Motion to the simpler way

of saying them.

1. An object moving in a straight line will keep moving in that

direction unless acted on by an outside force.

2. If an object is moved by a force, it will move in the direction of

the force. Also the greater the force, the faster the object moves.

c. For every action there is an equal and opposite reaction.

3. Task 2: Listening to confirm expectations (5 minutes)

Students use relevant information about the Laws of Motion and choose the term of physics from those given that is most suitable to complete every sentence.

Have you ever experienced 1……, which means going against changes in your state of 2……, for example, in a car while it is braking to a stop? The 3…… of the road on the locked wheels provides the unbalanced force to change the car's 4…… of motion, however, there is no 5…… force to change your own state of motion. Therefore, you continue in motion, sliding along the seat in a forward motion. A person in motion tends to stay in motion with the same 6…… and in the same direction unless there is a(n) 7…… force. In a car this can be a seat belt. Yes, seat belts are used to provide safety for passengers whose motion is governed by Newton's laws. The seat belt provides the unbalanced force which brings you from a state of motion to a state of 8……. So, what do you think might happen when you do not put on your seat belt and your car hits another one?

4. Task 3: Noticing and analysing language (reading) (10 minutes)

Students read the text on roller coaster rides and use the following words: ascent, kinetic, energy, friction, potential, track to complete it.

The basic elements of a roller coaster are kinetic energy and friction. Kinetic energy is the power that an object gets because it is moving. Friction is the force that stops something moving when it rubs on another surface. Both are used in roller coaster rides. The coaster cars ride along on a long winding ________. The track begins with a steep ________, which builds up a reservoir of ________ energy in the coaster car. The rest of the track's hills and valleys, twists and turns change the built-up ________ back and forth between potential energy to ________ energy. As the train moves, it gradually loses energy because of ________ until it reaches the end of the ride.

5. Task 4:

Students should find the following words such as: Newton, law, force, kinetic, friction, energy, potential
