Theme of the lesson

Forces. Composition of forces.The Newton's laws.

Learning objectives that are achieved at this lesson(Subject Programme reference)

to create possible algorithms of problem solving when bodies are in motion under the action of forces;

Lesson objectives

All students can define mass, inertia;

All students formulate Newton's first, second, and third laws;

Most people know under what conditions the body is at rest and under what conditions it moves evenly or evenly accelerated;

Explain examples and solve problems on Newton's laws.

Assessment criteria

§ Can give a definition of mass, inertia;

§ Formulates the first, second and third Newton's law;

§ Knows the conditions under which the body rests  under what

conditions does it move evenly;

§ Knows the reason for the change in the speed of body movement;

§ Explains examples and solves problems on Newton's laws.

Language objective

Vocabulary: Force, Resultant, mass, acceleration, weight, tension, contact force, friction, Inertia, and lift

Planned usage: Define newton second Law as “The resultant force acting on a body is proportional to the product of the mass and the acceleration of the body”

Learners have to be able to explain that the two forces that make a Newton’s third law pair act on different objects and are the same type of force

Values instilled at the lesson

Respect and creativity through group work, openness and lifelong learning

Resources

Beginning

0-5 min

Organizing time.

Concentration of attention

Post a lesson goal.

1.      Students are told to move different kinds of object themselves to verify Aristole's concept of motion.

2.      Students are asked several questions about their opinions about Aristole's concept.

(The inadequacy of Aristole's concept of motion in explaining the motion of an object which is thrown should be emphasized.)

Middle

5-35 min

1.      Galileo's pin and pendulum experiment is done to initiate another possible explanation of motion.

2.      Galileo's thought experiment is also introduced to explain the concept of natural state of motion of an object.

3.      The two different natural states of motion : at rest or moving forward with constant speed are introduced to the students by using an air track.

4.      The exact statement of Newton's First Law of Motion is stated.

5.      The motion of a light vehicle is used as an example to demonstrate Newton's First Law of Motion.

6.      The nature of friction is introduced.

7.      The fact that it is not easy to observe Newton's First Law of Motion is explained according to the existence of friction.

8.      Some experimental precautions that can reduce friction greatly are demonstrated.

(Emphasis should be placed on the fact that the object inGalileo's pin and pendulum experiment is suspended in air andis in not contact with any surface to get rid of friction. )Studentsshould be told to touch the air track when the track is inoperation to understand the function of the air track.Opportunities should be given to the students to push a lightvehicle on an air track. Emphasis should be placed on therelation between the surface of contact and friction. Themechanism of air track is used to consolidate the concept. The fact that the surface of contact is difficult to be neglected should be related to the belief of Aristole.)

End

35-40 min

At the end of the lesson, students analyze the work of each member of the group - “2 stars and 1 wish” at the same time evaluate each other.

And at the end on the sheet show their place and the place of their friend, indicating his name on the "tree with little men"

Homework

Additional information

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check students’ learning?

Cross-curricular links
Health and safety check
ICT links
Values links

Advanced students can assist other students with problems. Advanced students can research information of the interference of sea waves that form ‘rough waves’

Question of students and review of questions related to the learning objects. Student will be asked questions during the activity, notebooks will be reviewed, homework will be checked and exam questions related to this topic will be reviewed.

Activation "Circle of wishes" - the ability to analyze and evaluate the problem from different points of view

Reflection

Were the lesson objectives/learning objectives realistic? What did the learners learn today? What was the learning atmosphere like? Did my planned differentiation work well? Did I stick to timings? What changes did I make from my plan and why?
