The OLabs is based on the idea that lab experiments can be taught using the Internet, more efficiently and less expensively. The labs can also be made available to students with no access to physical labs or where equipment is not available owing to being scarce or costly. This helps them compete with students in better equipped schools and bridges the digital divide and geographical distances. The experiments can be accessed anytime and anywhere, overcoming the constraints on time felt when having access to the physical lab for only a short period of time.
The 'learning-enabled assessment' through OLabs facilitates in the assessment of; the procedural and manipulative skills of the experiment, the concepts and understanding of the experiment and a student's reporting and interpreting skills.
The development of OLabs includes the study and use of mathematical techniques to demonstrate the various complex functions in diverse areas of science. The labs make use of cutting edge simulation technology to create real world lab environments. Thorough study and research is done by research personnel for better understanding of the experimental procedures. Real lab scenarios are captured through live demonstration of the experiment so as to assimilate information on the procedures and lab equipment. Visualisation and development of the graphical symbols are done based on realistic situations and compared with the respective real equipment. Simulations are made interactive using various authoring tools, thus recreating and simulating a real lab environment.
The OLabs are hosted at www.olabs.edu.in. Access to OLabs is free for Schools upon registration.
A simulation to study the properties of acids using HCl solution and bases using NaOH solution by their reaction with Blue and Red Litmus solutions, Zinc metal and Solid sodium carbonate. The simulation and animations allow the student to perform the actual experiment online through the computer.
A simulation to determine the equivalent resistance of two resistors when connected in parallel. A student gets to study what resistance is, how it is measured and about resistance in a parallel combination. The simulation allows the student to perform the actual experiment online.
An interactive simulation that helps verify the first law (The incident wave, the normal to the reflecting surface and the reflected wave lie in one and the same plane) and the second law (The angle of incidence is equal to the angle of reflection) of the reflection (of light), which is relevant to sound waves as well.
Simulation that helps to make a right circular cylinder of given height and circumference of base. A cylinder is a geometric solid that is very common in everyday life, such as a soup can. If you take the cylinder apart you find it has two ends, called bases, which are usually circular.
the Pythagorean theorem is a relation in Euclidean geometry among the three sides of a right triangle (right-angled triangle). In terms of areas, it states: In any right-angled triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).
Present Perfect Continuous Tense : An action still continuing from the past to the present. In the Present Perfect Continuous tense, the action has been taking place for some time and is still ongoing. The duration for which the action has been going on is usually mentioned in the present perfect continuous tense.
