Benefits of ChemCollective Vlabs

00:21 Play video clippings of ChemCollective Vlabs tutorials available on our website.
00:27 To record this tutorial I am using,

Mac OS version 10.10.5

00:34 ChemCollective Vlabs version 2.1.0-3D
00:40 Java version 1.8.0
00:44 We need Java Runtime Environment to run Vlabs offline version.
00:49 To Install Java, please use the link shown.
00:53 To follow this tutorial learner should have knowledge of, high School Chemistry.
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.

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.
