Class 9
Experiments for Class IX in physical science that facilitate and improve the learning experience with a set of simulators, practical content and assessment. They are aligned to the CBSE syllabus and describe the working of real world experimentation concepts. The experiments cover various areas such as: sound, understanding physical properties of matter, etc.

 Force required to move a wooden blockNewton’s second law of motion precisely says the relation between force and acceleration. Newton's Third law of MotionAccording to Newton’s third law of motion, ‘ To every action there is an equal and opposite reaction. It must be remembered that action and reaction always act on different objects. Bell Jar ExperimentTo demonstrate that the sound wave requires a material medium for its propagation. Pressure Exerted by a Solid Iron Cuboid on SandTo observe and compare the pressure exerted by a solid iron cuboid on sand while resting on its three different faces and to calculate the pressure exerted in the three different cases. Verification of Archimedes' PrincipleTo establish the relation between the loss in weight of a solid when fully immersed in: a. tap water or b. strongly salty water, with the weight of water displaced by it by taking at least two different solids. Laws of Reflection of SoundAn experiment to verify the first law and the second law of the reflection of sound. Determination of Density of SolidTo determine the density of solid that is denser than water, using a spring balance and a measuring cylinder. Verification of Newton's Second LawNewton’s second law states that the acceleration a of a body is parallel and directly proportional to the net force F and inversely proportional to the mass m, i.e., F = ma. Velocity of a Pulse Propagated Through a SlinkyTo determine the velocity of a pulse propagated through a slinky.
