Lesson objectives

Students should be able to:

- compare the characteristics of electrostatic and gravitational fields;

- determine the similarities and differences of this type of field.

Successcriteria

Compares the characteristics of the gravitational and electrostatic fields.

Finds at least 4 differences and similarities between the gravitational and electrostatic fields.

Languageobjective

Orally and in writing describe the similarities and differences of the fields.

Subject vocabulary and terminology-sources of gravitational and electric fields, power and energy characteristics, energy, matter in this field.

Value links

Inculcation of values is carried out through consideration of the close relationship of the studied phenomena with the studied phenomena, a creative approach is encouraged. Also, the inculcation of values is carried out through / through respect for the opinions of others, attention to their answers

Study material:The concept of field is one of the most important physical concepts. It replaces the model of "action at a distance" and allows us to explain physical phenomena using a purely local cause and effect – an object (mass) does not fall, because The earth at a distance attracts it to itself and the local gravitational field of the Earth exerts force on it. Since students are familiar with gravitational fields(at least in their effects), they need to use them as an analogy for an electric field.

Use the gravitational field of the Earth they are familiar with, enter a representation of the force line for both the Central field (for the Earth) and the uniform field (for example, in a room on The earth's surface).

Various simple electrostatic experiments can be used to demonstrate electrostatic forces between charged objects. The same should be done with the gravitational field, and at the end of this work, students should understand how to draw a diagram of the force line to represent the electric field near a uniformly charged positive or negative area (or point charge). It may also be worth demonstrating and discussing friction, contact, and induction electrification with students.

When the electric field strength is determined, do the same with the gravitational field (g):

E =F/qo  (Н/Кл)

g = F/m (Н/кг)

Next, it is necessary to highlight that: the charge is the source of the electric field, and the electric field acts on the charges. Mass is the source of the gravitational field, and gravitational fields affect the masses.

Invite students to create a table of similarities and differences between the gravitational and electrostatic fields, which should reflect the following:

1.    Sources of electrostatic and gravitational fields.

2.    The force acting on a body in the gravitational and electrostatic field

3.    Power characteristics of electric and gravitational fields (formula and direction).

4.    Schematic representation of gravitational and electrostatic fields

5.         Graph of the dependence of the intensity of these fields on the distance from the charge and the inverse square of this distance.

Typical tasks solution. At this stage, a differentiated approach to learning is implemented.

1.         What is a field? What types of fields do you know?

2.         What laws are subject to the movement of bodies in a gravitational field? electric field?

3.         What characteristics of the fields are known to you?

4.         What do gravitational and electric fields have in common?

5.Will the force of interaction between electrons change if they are transferred from the gravitational field to the electric one?

During the discussion, clearly show how to organize information, such as charts and tables.

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

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

Health and safety check

Formative assessment

Mutual evaluation

Self-esteem

All these types will help students to build the right trajectory to the goal

Differentiation will be realized in the use of tasks .Most of the students will cope with the tasks and will advise other students who are experiencing difficulties .The teacher will support the students during the lesson

Safety briefing and rules of behavior in the study of physics.
