ICSE Syllabus Class 9 Physics 2024-25
CISCE has designed the Physics syllabus with the objective that students gain knowledge and understand the key concepts, laws, and principles of physics, alongside developing practical skills such as using equipment, noting observations, and creating diagrams and graphs. This involves understanding terms, facts, concepts, definitions, and processes in physics, while also inculcating the ability to apply this knowledge in practical scenarios.

Physics Paper

Total Marks: 80

Time: 2 Hours

The paper will be divided into two sections, Section I (40 marks) and Section II (40 marks). Section I (compulsory) will consist of short answer questions. Section II will consist of six questions out of which candidates will be required to answer any four questions.

Note: Unless otherwise specified, only SI Units are allowed to answer questions.

Physics Class 9 ICSE Syllabus: Internal Assessment
Candidates will conduct experiments according to the given instructions. The experiment could be from topics not mentioned in the syllabus but their theoretical knowledge is also not necessary while performing the experiments. Students should follow instructions, record readings accurately, and present them neatly. Graphs may be required. Understanding concepts like least count, significant figures, and basic error handling is important.

In the Physics ICSE Syllabus Class 9, a comprehensive list of the experiments as mentioned by CISCE is presented.

Internal Assessment of Practical Work
The following are the experiments that a student should perform.

Determine the least count of the Vernier calipers and measure the length and diameter of a small cylinder (average of three sets) – maybe a metal rod of length 2 to 3 cm and diameter 1 to 2 cm.
Determine the pitch and least count of the given screw gauge and measure the mean radius of the given wire, taking three.
Measure the length, breadth, and thickness of a glass block using a meter rule (each reading correct to an mm), taking the mean of three readings in each case. Calculate the volume of the block in cm3 and m3. Determine the mass (not weight) of the block using any convenient balance in g and kg. Calculate the density of glass in cgs and SI units using mass and volume in the respective units. Obtain the relation between the two density units.
Measure the volume of a metal bob (the one used in simple pendulum experiments) from the readings of water level in a measuring cylinder using the displacement method. Also, calculate the same volume from the radius measured using Vernier calipers. Comment on the accuracies.
Obtain five sets of readings of the time taken for 20 oscillations of a simple pendulum of lengths about 70, 80, 90, 100, and 110 cm; calculate the time periods (T) and their squares (T2 ) for each length (l). Plot a graph of l vs. T2. Draw the best-fit straight-line graph. Also, obtain its slope. Calculate the value of g in the laboratory. It is 4π2 x slope.
Take a beaker of water. Place it on the wire gauze on a tripod stand. Suspend two thermometers – one with Celsius and the other with Fahrenheit scale. Record the thermometer readings at 5 to 7 different temperatures. You may start with ice-cold water, then allow it to warm up, and then heat it slowly, taking the temperature (at regular intervals) as high as possible. Plot a graph of TF vs. TC. Obtain the slope. Compare with the theoretical value. Read the intercept on the TF axis for TC = 0.
Using a plane mirror strip mounted vertically on a board, obtain the reflected rays for three rays incident at different angles. Measure the angles of incidence and angles of reflection. See if these angles are equal.
Place three object pins at different distances on a line perpendicular to a plane mirror fixed vertically on a board. Obtain two reflected rays (for each pin), fixing two pins in line with the image. Obtain the positions of the images in each case by extending backward (using dashed lines) the lines representing reflected rays. Measure the object distances and image distances in the three cases. Tabulate. Are they equal? Generalize the result.
Obtain the focal length of a concave mirror (a) by distant object method, focusing its real image on a screen or wall, and (b) by one needle method removing parallax or focusing the image of the illuminated wire gauze attached to a ray box. One could also improvise with a candle and a screen. Enter your observations in numbered rows.
Connect a suitable dc source (two dry cells or an acid cell), a key, and a bulb (maybe a small one used in torches) in series. Close the circuit by inserting the plug in the key. Observe the bulb as it lights up. Now open the circuit, and connect another identical bulb in between the first bulb and the cell so that the two bulbs are in series. Close the key. Observe the lighted bulbs. How does the light from any one bulb compare with that in the first case when you had only one bulb? Disconnect the second bulb. Reconnect the circuit as in the first experiment. Now connect the second bulb across the first bulb. The two bulbs are connected in parallel. Observe the brightness of any one bulb. Compare with previous results. Draw your own conclusions regarding the current and resistance in the three cases.
Plot the magnetic field lines of Earth (without any magnet nearby) using a small compass needle. On another sheet of paper, place a bar magnet with its axis parallel to the magnetic lines of the earth, i.e., along the magnetic meridian or magnetic north-south. Plot the magnetic field in the region around the magnet. Identify the regions where the combined magnetic field of the magnet and the earth is (a) strongest, (b) very weak but not zero, and (c) zero. Why is the neutral point so-called?
Using a spring balance, obtain the weight (in N) of a metal ball in the air and then completely immerse it in water in a measuring cylinder. Note the volume of the ball from the volume of the water displaced. Calculate the upthrust from the first two weights. Also, calculate the mass and then the weight of the water displaced by the bob M=V.ρ, W=mg). Use the above result to verify Archimedes’ principle.
Tips to Prepare for the ICSE Class 9 Physics Exam
The following are some tips to prepare for the ICSE class 9 Physics exam.

Prepare a Timetable
Once you know the ICSE Class 9 Physics Syllabus, prepare a study timetable. Divide one and a half hours every day for the physics subject. Dedicate some extra time for more difficult topics in the ICSE Class 9 Physics Syllabus.

Also, take some frequent breaks between studying. This helps relax your mind and lets you focus on the concepts clearly.

Refer to the Good Study Materials
Referring to good study material for ICSE Class 9 Physics Syllabus is important. This is because good study material will solve half of your mark as the concepts will be clear and precise to the point. Also, select the study materials that come with a sample paper so that you will know the question type.

Practice More
Once you are done with a topic from the ICSE Class 9 Physics Syllabus, practice more questions from that topic. This helps you to understand the questions better, and you will remember them for a long time. Moreover, speed and accuracy are very important for solving Physics problems which will be improved from practice.

Solve Previous Year’s Question Papers
Once you are done with the ICSE Class 9 Physics Syllabus, solve the previous year’s question papers. This will help you to get a grip on the Physics subject. When you solve the actual question paper, you will know how you performed for each question.

Also, you should analyze your mistakes after solving the previous year’s question paper. This should be done on that day itself so that you will realize the mistakes made and will not repeat them.

Attempt Mock Tests
Attempting a mock test is one of the efficient ways to practice for the test. Go for mock tests that have the latest ICSE Class 9 Physics Syllabus. This way, the questions will be on the latest topics. This also reduces stress and promotes your preparation level.
