|00:58|| 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.|
