Demonstration versions of the OGE in physics (grade 9).

This page contains demo versions of the OGE in physics for grade 9 for 2009 - 2019.

Demo options OGE in physics contain two types of tasks: tasks where you need to give a short answer, and tasks where you need to give a detailed answer.

To all tasks of all demonstration versions of the OGE in physics Answers are provided, and long-response items have detailed solutions and grading instructions.

To complete some tasks, you need to assemble an experimental setup based on standard kits for front-line work in physics. We also post a list of necessary laboratory equipment.

Changes in physics demos

Demonstration versions of the OGE in physics 2009 - 2014 consisted of 3 parts: tasks with a choice of answers, tasks with a short answer, tasks with a detailed answer.

In 2013 in demo version of the OGE in physics the following were introduced changes:

  • 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 did not change, 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 multiple-choice tasks has been changed: the answer now needs to be written down number with the number of the correct answer(rather than circling).

In 2016 in demo version of the OGE in physics happened significant changes:

  • Total number of jobs reduced to 26.
  • Number of short answer questions increased to 8
  • Maximum score for all the work did not change(still - 40 points).

IN demo versions of the OGE 2017 - 2019 in physics compared to demo version 2016 there were no changes.

MECHANICAL PHENOMENA.
Mechanical movement. Trajectory. Path. Moving.
Mechanical motion is the change in the position of a body in space relative to other bodies over time. Exist different kinds mechanical movement.

If all points of the body move equally and any straight line drawn in the body remains parallel to itself during its movement, then such a movement is called translational.
The points of a rotating wheel describe circles relative to the axis of this wheel. The wheel as a whole and all its points perform rotational motion.
If a body, for example a ball suspended on a thread, deviates from a vertical position first in one direction or the other, then its motion is oscillatory.

The definition of the concept of mechanical motion includes the words “relative to other bodies.” They mean that a given body can be at rest relative to some bodies and move relative to other bodies. Thus, a passenger sitting on a bus moving relative to buildings also moves relative to them, but is at rest relative to the bus. A raft floating along a river is stationary relative to the water, but moves relative to the shore. Thus, when speaking about the mechanical movement of a body, it is necessary to indicate the body relative to which this body is moving or at rest. Such a body is called a reference body. In the above example with a moving bus, a house, or a tree, or a pillar near a bus stop can be chosen as a reference body.

Preparation for the OGE and the Unified State Exam

Basics general education

Line UMK A.V. Peryshkin. Physics (7-9)

Preparing for the OGE in physics: task No. 23

In the 9th grade, schoolchildren are faced with mandatory state exams for the first time. 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 provide 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, so it takes the most time - 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 held on the territory of another school, the teacher can visit 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 the specified values. If they do not match, then in special forms indicate true values, and not those recorded in 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
  • Work of electric current
  • Electric current power.

Type 2. “Presenting experimental results in the form of tables or graphs and formulating 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 of series connection of 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 is worth looking again to see if anything is missing: a schematic drawing, a formula for calculating the required value, the results of direct measurements, calculations, the numerical value of 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 the 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.
