| 00:01 | Welcome to this spoken tutorial on Overview of ChemCollective Vlabs. |
| 00:07 | In this tutorial we will learn, About ChemCollective Vlabs |
| 00:13 | About ChemCollective Vlabs offline interface
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. |
| 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. |
