DEVELOPMENT OF A SUIT OF VIRTUAL EXPERIMENS FOR PHYSICS ANDCHEMISTRY UNDERGRADUATE LABORATORIES.Inadequate funding and lack of equipment is a bane of undergraduate laboratory practicein Physics and Chemistry. If it is possible for students to have virtual equivalents of theseexperiments, they can easily perform them on-line thereby increasing their understandingand speed of completion if and when they get to the real lab.Using Physics and Chemistry laboratory manuals of freshmen at a university, the authorshave developed virtual laboratories for selected experiments. These include Calorimetry,Specific Heat Capacity, Latent Heat Capacity, Ohm’s law, pH measurement and Acidbase Titration. The idea is to eventually upgrade these in future to a MOOCs suit that anumber of universities can use. This work involves a synergy of faculties in Physics,Chemistry, Electronics and Computer Engineering.The design process used by authors is purely graphical; it involves the use of imageswhich are given certain properties programmatically to behave like the liveequipment when interacted with by the students on their computers using their keyboardsand mice.An apparatus bench containing the materials and equipment for each experiment ispresented with adequate prompts for each step to be taken by students. A help guidedescribing the theory and procedure for performing each experiment in real laboratoryThe programming sequence (algorithms) is implemented using flash or HTML5. HTML5in particular is a potential candidate for cross-platform mobile applications. Many of itsfeatures have been built with the consideration of being able to run on low-powereddevices such as smart phones and tablets.Comparison of performances of students who had previously done the virtual labs beforetaking the real lab and those who had not will be carried out.
