To record this tutorial I am using, Mac OS version 10.10.5
ChemCollective Vlabs version 2.1.0-3D
Java version 1.8.0
We need Java Runtime Environment to run Vlabs offline version.
To Install Java, please use the link shown.
To follow this tutorial learner should have knowledge of, high School Chemistry.
The ChemCollective Vlabs is a simulation of a chemistry lab. It is available in both online and offline modes.
It is available free of charge to all educators and students.
ChemCollective Virtual labs are a part of National Science Digital Library(NSDL).
I have opened the ChemCollective Vlabs interface.
The interface has standard menu items like File, Edit, Tools, View and Help.
I will click on Glassware drop-down and select 250 mL Beaker.
Right-click on 250 mL Beaker.
Its context menu opens. This menu includes Edit menu options along with other options.
Click on View menu and select Themes.
A sub-menu opens with the following options.
By default Metal theme is selected. I will select Presentation theme.
Click on Help menu and select Contents.
Virtual Lab Help opens. It has Table of Contents.
Each heading has information about how to use Vlabs.
Some of the benefits of Vlabs are listed here.
Vlabs allow careful observation and safe measurement of parameters
Useful in experiments that involve risks to the health and physical integrity of learners.
Students can experiment without limitations of space or time.
Vlabs are cheaper, faster, less risky and more affordable than the real process.
Teachers can use Vlabs as pre-lab exercise.
Vlabs will help students learn basic laboratory techniques.
Vlabs can be used as in-class activities for individuals or teams.
