Preparation for the OGE in physics online. Demonstration versions of the OGE in physics (grade 9)
According to statistics, physics is at the level high school without in-depth study of the subject, one of the most difficult disciplines. It is extremely difficult for students to pass it with a high score, since the subject is taught rarely (about 1-2 lessons per week), experiments and laboratory work– a rarity. But students can pass the tests successfully.
To get the maximum grade, you should not only study at school, but devote a lot of time to self-education, attend courses, take tests online - use all opportunities to consolidate knowledge.
The range of tasks includes various tasks, questions, tests of knowledge of theory, tasks for carrying out various calculations. This applies to the first part of the exam. The second part requires not only knowledge of the theory, but also the ability to use it experimentally. The subjects are offered several sets for experiments - you can choose any one on the topic that is closest to you (optics, mechanics, electricity).
Physics tasks are divided into three groups according to difficulty level - basic, advanced and high.
The highest number of points is awarded for the experiment. Difficulties may arise because students rarely do laboratory work at school.
- To begin with, we recommend that you carefully read P – this will allow you to competently plan the preparation process. Without a preparation plan, it is impossible to achieve a high score. Highlight for each topic a certain amount time, gradually move towards the goal. Regular preparation according to the plan allows you not only to assimilate knowledge well, but also to get rid of anxiety.
- Assessment of knowledge level
To do this, you can use two methods: the help of a teacher or tutor, taking an online test, which will reveal problematic topics. With the help of a specialist, you can quickly assess problems and create a plan to effectively eliminate them. Regularly passing training tests – required element successfully passing the exam. - Problem solving
The most important and difficult stage. At the level schooling It is important to remember the solution algorithms, but if the tasks are not easy, it is recommended to take the help of a mentor and regularly solve problems on your own. - “I’ll solve the OGE in physics” - the opportunity to take tests in online mode, consolidate knowledge, train to perform them for a while, memorize solution algorithms. Regular testing also helps identify weak points in knowledge and preparation.

Preparing for the OGE in physics: task No. 23
In the 9th grade, schoolchildren first encounter compulsory state exams. What does this mean for a teacher? Firstly, the task is to prepare children for intensive preparation for certification work. But the most important thing: not just to give complete knowledge of your subject, but to explain what kind of tasks need to be completed, analyze typical examples, errors and give students all the tools to successfully pass the exam.When preparing for the OGE, experimental task No. 23 raises the most questions. It is the most difficult, and accordingly, the most time is allocated to it - 30 minutes. And for its successful completion you can get the most points - 4. This task begins the second part of the work. If we look into the codifier, we will see that the controlled elements of content here are mechanical and electromagnetism phenomena. Students must demonstrate ability to work with physical instruments and measuring instruments.
There are 8 standard sets of equipment that may be needed for the exam. Which ones will be used becomes known a few days before the exam, so it is advisable to conduct additional training before the exam with those tools that will be used; Be sure to repeat how to take readings from instruments. If the exam is being held on the premises of another school, the teacher can travel there in advance to view the kits ready for use. A teacher preparing instruments for an exam should pay attention to their serviceability, especially those subject to wear. For example, using an old battery may result in the student simply not being able to set the required current.
It is necessary to check whether the devices match with specified values. If they do not match, then the true values are indicated on special forms, and not those recorded in the official sets.
The teacher responsible for conducting the exam may be assisted by a technical specialist. He also monitors compliance with safety regulations during the exam and can intervene in the progress of the task. Students should be reminded that if they notice any malfunction of any equipment while performing a task, they should report it immediately.
There are three types of experimental tasks found in the physics exam.
Type 1. “Indirect measurements of physical quantities.” Includes 12 topics:
- Density of matter
- Archimedes' force
- Sliding friction coefficient
- Spring stiffness
- Period and frequency of oscillations of a mathematical pendulum
- Moment of force acting on the lever
- Work elastic force when lifting a load using a movable or stationary block
- Work of friction force
- Optical power of the collecting lens
- Electrical resistance of the resistor
- Job electric current
- Electric current power.
Type 2. "Presentation" experimental results in the form of tables or graphs and formulation of a conclusion based on the experimental data obtained.” Includes 5 topics:
- Dependence of the elastic force arising in the spring on the degree of deformation of the spring
- Dependence of the oscillation period of a mathematical pendulum on the length of the thread
- Dependence of the current strength arising in the conductor on the voltage at the ends of the conductor
- Dependence of sliding friction force on force normal pressure
- Properties of an image obtained using a converging lens
Type 3. “Experimental verification of physical laws and consequences.” Includes 2 topics:
- Law serial connection resistors for electrical voltage
- The law of parallel connection of resistors for electric current
Preparing for the OGE in physics: tips for students
- It is important to very accurately write down everything that the rules require on the answer form. When checking your work, it’s worth taking another look to see if you missed anything: schematic drawing, formula for calculating the desired value, results of direct measurements, calculations, numeric value the desired value, conclusion, etc., depending on the conditions. The absence of at least one indicator will result in a decrease in score.
- For additional measurements entered into the form, the score is not reduced.
- Drawings must be done very carefully; sloppy diagrams will also take away points. It is important to learn to control the indication of all units of measurement
- When writing down the answer, the student should not indicate the error, but it is worth conveying to him the information that the examiner has criteria and the correct answer already contains the boundaries of the interval within which the correct result may be.
Preparation for the exam in general and for experimental task in particular cannot be spontaneous. Without constantly developing skills in working with laboratory equipment, it is almost impossible to complete tasks. Therefore, teachers are recommended to familiarize themselves with demo versions of the exam paper and analyze typical problems during laboratory tests.

- was Added task 8 with multiple choice- for thermal effects,
- was added task 23 with short answer– to understand and analyze experimental data presented in the form of a table, graph or figure (diagram),
- was the number of tasks with a detailed answer has been increased to five: to the four tasks with a detailed answer of part 3, task 19 of part 1 was added - on the application of information from the text of physical content.
In 2014 demo version of the OGE in physics 2014 in relation to the previous year in structure and content hasn't changed, however, there were criteria changed grading tasks with a detailed answer.
In 2015 there was variant structure changed:
- The option became consist of two parts.
- Numbering tasks became through throughout the entire version without letter designations A, B, C.
- The form for recording the answer in tasks with a choice of answers has been changed: the answer now needs to be written down number with the number of the correct answer(not circled).
In 2016 in demo version of the OGE in physics happened significant changes:
- Total number of tasks reduced to 26.
- Number of short answer questions increased to 8
- Maximum score for all the work hasn't changed(still - 40 points).
IN demo versions of the OGE 2017 - 2019 in physics compared to demo version 2016 there were no changes.

Fog
Under certain conditions, water vapor in the air partially condenses, resulting in water droplets of fog. Water droplets have a diameter from 0.5 microns to 100 microns.
Take a vessel, fill it halfway with water and close the lid. The fastest water molecules, overcoming the attraction from other molecules, jump out of the water and form steam above the surface of the water. This process is called water evaporation. On the other hand, water vapor molecules, colliding with each other and with other air molecules, can randomly end up at the surface of the water and turn back into liquid. This is steam condensation. Ultimately, at a given temperature, the processes of evaporation and condensation are mutually compensated, that is, a state of thermodynamic equilibrium is established. The water vapor located in this case above the surface of the liquid is called saturated.
If the temperature is increased, the rate of evaporation increases and equilibrium is established at a higher density of water vapor. Thus, the density of saturated steam increases with increasing temperature (see figure). 
Dependence of saturated water vapor density on temperature.
For fog to occur, the steam must become not just saturated, but supersaturated. Water vapor becomes saturated (and supersaturated) with sufficient cooling (AB process) or during additional evaporation of water (AC process). Accordingly, the falling fog is called cooling fog and evaporation fog.
The second condition necessary for the formation of fog is the presence of condensation nuclei (centers). The role of nuclei can be played by ions, tiny droplets of water, dust particles, soot particles and other small contaminants. The more air pollution, the denser the fog.
16.
The graph in the figure shows that at a temperature of 20 °C the density of saturated water vapor is 17.3 g/m 3
. This means that at 20 °C
1) at 1 m 3 air contains 17.3 g of water vapor
2) at 17.3 m 3 air contains 1 g of water vapor
3) relative air humidity is 17.3%
4) air density is 17.3 g/m 3
17.
For which processes indicated in the figure can evaporation fog be observed?
1) AB only 2) AC only 3) AB and AC 4) neither AB nor AC
18.
Which statements about fogs are true? A.
Urban fogs, compared to fogs in mountainous areas, are characterized by a higher density. B.
Fogs are observed when the air temperature rises sharply.
1) only A is true 2) only B is true 3) both statements are true 4) both statements are false
19. Match between technical devices(devices) and physical laws underlying the principle of their operation.
20. Establish a correspondence between physical quantities and the formulas by which these quantities are determined.
