|| The ChemCollective Vlabs is a simulation of a chemistry lab. 

It is available in both online and offline modes. 

|- 
|| 01:07
|| It is available free of charge to all educators and students. 

|- 
|| 01:13
||'''ChemCollective Virtual''' labs are a part of '''National Science Digital Library'''(NSDL). 

|- 
||01:19
|| I have opened the '''ChemCollective Vlabs''' interface. 

|- 
|| 01:23
|| The interface has standard menu items like 

'''File''', '''Edit''', '''Tools''', '''View''' and '''Help'''. 

|- 
|| 01:37
|| I will click on '''Glassware''' drop-down and select '''250 mL Beaker'''. 

|- 
|| 01:43
|| Right-click on '''250 mL Beaker'''. 

|- 
|| 01:47
|| Its context menu opens. 

This menu includes '''Edit menu''' options along with other options. 

|- 
|| 01:56
|| Click on '''View''' menu and select '''Themes'''. 

|- 
|| 02:00
|| A sub-menu opens with the following options. 

|- 
|| 02:04
|| By default '''Metal''' theme is selected. 

I will select '''Presentation''' theme. 

|- 
|| 02:11
|| Click on '''Help''' menu and select '''Contents'''. 

|- 
|| 02:15
|| ''' Virtual Lab Help''' opens. It has '''Table of Contents'''. 

|- 
|| 02:21
|| Each heading has information about how to use '''Vlabs'''. 

|- 
||02:30
|| Some of the benefits of Vlabs are listed here. 

|- 
|| 02:34
||  '''Vlabs''' allow careful observation and safe measurement of parameters 

|- 
|| 02:40
||  Useful in experiments that involve risks to the health and physical integrity of learners. 

|- 
|| 02:47
|| Students can experiment without limitations of space or time. 

|- 
|| 02:52
||  '''Vlabs''' are cheaper, faster, less risky and more affordable than the real process. 

|- 
|| 02:59
||  Teachers can use '''Vlabs''' as pre-lab exercise. 

|- 
||03:03
|| '''Vlabs''' will help students learn basic laboratory techniques. 

|- 
|| 03:08
||  '''Vlabs''' can be used as in-class activities for individuals or teams.
