Each Simulation Pack in the list below contains the following:
A video snippet that explains basic concepts of the concerned topic, and touches upon operational controls of the simulation
One or more Interactive 3D simulations
Assessment questions (MCQs)
Objective here is to help a user explain (or understand) the difference between conventional direction of current versus direction of flow of electrons in a conductor. Students also get to understand why the brightness of a bulb changes when we change an external resistor in the circuit. Interactive aspects include ability to change the conductor, and resistors to see the impact of those changes in the circuit.
Objective here is to show the workings of a DC motor, and explain what makes a coil to rotate, as well as change its speed. Fleming’s Left Hand is used to explain the direction of motion of the coil, in conjunction with force acting upon the coil. A user is allowed to “play with” the DC motor parts and understand the impact of changes they make to those parts.
Objective is to understand how sound travels in different medium. A sound producing device is used that sends out a beep every second. Watch how sound waves travel in Air. When sound is sucked out of a bell jar containing the sound device, watch what happens to the volume of sound. Does sound propagate in vacuum ? Compare speed of Sound waves in air with that in water and in a solid steel rod.
Objective is to demonstrate how light bends (due to refraction or reflection) when it travels from medium to another. Explore what happens when light moves from rarer to denser medium, and vice-versa. Understand when does refraction take place, versus total internal reflection. Snell's law comes in handy to understand the concept of bending of light. Additionally learn how a change of medium causes an impact to bending of light. Concept of refractive index is elucidated. Watch what happens to the angle of refraction when medium is changed.
Objective here is to help understand the forces acting on an object traveling in a circular motion. A common real life example is taken to depict this scenario. A person standing on a merry-go-round without any support, tries to balance himself in the ride. A curious mind will wonder what causes such a person to slip and fall away from the ride due to various forces acting on him.
