What are virtual labs?

There's an old expression that says

'a picture's worth a thousand words!'

I wish some of my college professors had heard that! Basic educational psychology has confirmed what the originator of that expression had figured out long before anyone knew about learning modalities. From a pedagogical science perspective, the rationale for use of Virtual Labs is much like the same for actual lab activities.

  • Tell me. I may not get it, I'm sure to forget it.
  • Show me. I may get it, I'll remember it for a little while.
  • Have me do it. I'll understand it, it may stick for awhile.

Anyone who has seriously taught anything knows...

  • Have me teach it. I'll really know it, I'll remeber it for a long time.
  • And, anyone that has every written programs to model something has learned...
  • Have me program it. Guru. Can you say eternity!

An excellent strategy for differentiating instruction is the use of Virtual Labs where students can do everything from merely exercise existing ones to designing and programming their own unique applications. From my own experience with computer graphics, programming applications requires even more rigorous study of the application than does teaching it.

Computers are far more particular to the accuracy of your explanations (algorithms) and are far less forgiving!

examples of virtual labs




use the regular google search with the topic you are looking for and add any or all of the following words to your search

 applet  simulation  Java  physlet   virtual    'virtual lab'   'virtual labs'   animation  application

tip: if you use only one of the keywords above put a plus sign in front of the it (i.e. +applet) to return only sites with 'applet' in them.

don't put a plus in front of too many keywords or you will narrow your search too much

Use the following to search for fluid density virtual labs. Press the 'PHYSICS' button  when you are ready to search the web.


A new window with the Google search results should pop up when the search is done.

(if it doesn't work check if you are blocking pop-ups! and try pasting the same string into a Google search page.).

The last time I tried that search I got 975 sites back. Try it  again with '+virtual labs'


this one returned 11,100 hits

Now let;s try it with the name of one of the principles


this one really narrowed it down but still got 185 hits

Virtual labs are software tools that make it possible to experience the essential aspects of a real world activity through the use of software tools and the world wide web.

VIRTUAL LABS are software tools  that make it possible to observe and how real world systems behave under a variety of user controlled conditions without having the real thing or a physical model of it.

Many simulations found on the web, while interesting to look at and helpful in visualization, are merely animations. They lack interactivity and the provision for variation or the independent variables that one would want to modify.

Virtual Labs are INTERACTIVE SIMULATIONS that allow the user to modify the input variables, re-run the simulation with the modified inputs, and observe the results of those changes

ideally the user will be provided with data in addition to animation so that empirical analysis can be made

They are called different things from applets, to simulations, to plug-ins

Virtual Labs can be applets, animations, simulations, plug-ins, standalone application, calculators, etc.

Applets, animations, simulations, plug-ins, standalone application, calculators, etc. are not all Virtual Labs

They can be both web based or off-line tools

They are created with a variety of software tools & methods
