LESSON PLAN

Unit : SMPN 5 Probolinggo

Grade / Term : VII / 1

Subject : SCIENCE – Physics

Topic : 1. Quantities and Their Units

Time Allocation : 40 minutes

1. Standard of Competence

To understand the scientific procedure for learning the natural objects using tools.

2. Basic Competence

1.1. To describe fundamental and derived quantities and their units.

3. Indicator to achieve Competence

1. To identify the physics quantities in daily life and then to classify them in fundamental and derived quantities.

2. To use the international units in measurements.

4. Objectives

Students are able to :

1. Identify the physics quantities in daily life and then to classify them in fundamental and derived quantities.

2. Differentiate the fundamental and derived physical quantities.

3. Mention the units of fundamental and derived physical quantities.

4. Show the derived quantity units from fundamental quantity units

5. Use the international units in measurements.

5. Subject Materials

o Measuring is to compare a physical quantity of an object with similar quantity used as a unit.

o The result measurement is useful it it uses a standard measurement.

o Quantities are everything that can be measured, has value that can be expressed by number, and has the certain units.

o The physical quantity divided into: fundamental quantities and derived quantities.

6. Learning approach and methods

1. Approach : Cooperative learning

2. Methods : Discussion, presentation.

7. Teaching – Learning Process

Phases	Activities
Opening (5 minutes)	Introduction - Show to students some examples of products - Ask students to mention some physical quantities which are labeled on the products. Motivation Can you mention physics quantities in the classroom?
Main (25 minutes)	The teacher explains the fundamental and derived quantities and their units. The teacher asks the students in a group of four to discuss and make a list of physical quantities which are used in daily life. Students are asked to classify the list into fundamental and derived quantities. Some groups are asked to deliver a presentation of the result of discussion. The other groups are asked to rise questions.

Closure (10 minutes)

The students draw conclusions guided by the teacher. The students do the post-test.

8. Learning Resources
