ONLINE LABS

The Online Labs 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 features include :
   * Content aligned to NCERT/CBSE and State Board Syllabus.
   * Physics, Chemistry, Biology Labs from Class 9 to Class 12. English and
     Maths lessons for Class 9 and 10.
   * Interactive simulations, animations and lab videos.
   * The concepts and understanding of the experiment.
   * The ability to perform, record and learn experiments - anywhere, anytime,
     and individualised practice in all areas of experimentation.

The 'learning-enabled assessment' through Online Labs 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 online labs 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 online labs are hosted at www.olabs.edu.in. Access to Online Labs is free
for Schools upon registration.


FEATURED SIMULATION

Properties of acid and bases



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.

 

Equivalent resistance



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.

 

Laws of reflection of sound



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.

 

Right Circular Cylinder



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.

 

Pythagoras theorem



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).

 

Tense conversion



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.

 

Direct and Indirect Speech



Direct Speech: In direct speech, we convey the message of the speaker in his own
actual words without any change to another person. Indirect Speech: In indirect
speech, we convey the message of the speaker in our own words to another person.
