♣ Good to have virtual experiences of real lab experiments~Babu Lal Mali, Demonstration Multipurpose School, Ajmer. ♣ It is good for students for visual learning.Good for the schools also ~ Rakesh Khandelwal, St.Mary's Convent Sr Sec School, Ajmer. Schools Feedback Students can access the lab activities at home as well & revise ~ Avijeet Sengupta, Mahaveer Public School Jaipur. ![]() The OLabs are hosted at Access to OLabs is free for Schools upon registration. Simulations are made interactive using various authoring tools, thus recreating and simulating a real lab environment. Visualisation and development of the graphical symbols are done based on realistic situations and compared with the respective real equipment. Real lab scenarios are captured through live demonstration of the experiment so as to assimilate information on the procedures and lab equipment. Thorough study and research is done by research personnel for better understanding of the experimental procedures. The labs make use of cutting edge simulation technology to create real world lab environments. The development of OLabs includes the study and use of mathematical techniques to demonstrate the various complex functions in diverse areas of science. 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 ability to perform, record and learn experiments - anywhere, anytime, and individualised practice in all areas of experimentation.The concepts and understanding of the experiment.Interactive simulations, animations and lab videos.English and Maths lessons for Class 9 and 10. Physics, Chemistry, Biology Labs from Class 9 to Class 12.Content aligned to NCERT/CBSE and State Board Syllabus.How much an object's temperature increases depends on how intense the light striking its surface is, how long the light shines on the object, and how much of the light is absorbed. Light and other electromagnetic waves can warm objects. Light energy is associated with the frequency of electromagnetic waves. Electrical energy is associated with an electric current in a circuit. Chemical energy is associated with the composition of a substance. Elastic energy is associated with the stretching or compressing of an elastic object. ![]() Gravitational energy is associated with the height of an object above a reference point. Thermal energy is associated with the temperature of an object. Motion energy is associated with the speed of an object. Energy appears in different forms and can be transformed within a system. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one 2) mechanically, when two objects push or pull on each other over a distance 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device or 4) by electromagnetic waves. Sometimes when energy appears to be lost, it actually has been transferred to a system that is so large that the effect of the transferred energy is imperceptible. ![]() ![]() Whenever energy is lost from somewhere, it must have gone somewhere else. Whenever energy appears in one place, it must have disappeared from another. When warmer things are put with cooler ones, heat is transferred from the warmer ones to the cooler ones. When warmer things are put with cooler ones, the warmer things get cooler and the cooler things get warmer until they all are the same temperature.
