Animating your chemistry classes
Ian Torrie
St Cuthbert’s College, Epsom, Auckland (ian.torrie@stcuthberts.school.nz)
Computer generated animations can illustrate concepts that would otherwise be difficult:
Note: You will need to download both the Adobe
Flash and Shockwave players – if you don’t already
have it take the time to download Adobe Acrobat
Reader also.
• Processes occurring at the molecular level, e.g.,
dissolving or melting.
How to use animations
Why use animations
• Processes that occur over very short or very long
time periods. e.g., continental drift.
• The impact of a wide range of variables very
quickly, e.g., effect on image of changing lens focal length.
• Processes that we cannot directly experience,
e.g., nuclear fusion, star formation.
They can also include 3-D concepts, e.g., shapes of
molecules, eclipses, retrograde motion.
They can be used to visually compare and contrast,
e.g., meiosis vs. mitosis
They can be used to introduce a concept or as revision or catch-up of a topic already covered.
They are better than movies because they do not
have to be delivered in a linear fashion and can be
interactive with the user changing variables, etc.
Students who have grown up used to special effects
and flash technology can relate to them.
Types of animations
There are a number of types of animations that can
be played on any web browser (such as Internet Explorer or Firefox or Safari) and are therefore platform independent. (i.e., PC or Mac):
• Simple animated GIFs (essentially a succession
of diagrams in GIF format).
• Javascript - a scripting language incorporated in
web pages.
• JavaApplets - requires Java support to be loaded
on your computer - usually pre-installed.
• Shockwave or Flash - self contained animations
that can play in any browser that has the appropriate “plug-ins” installed (available free from
http://www.adobe.com/downloads).
Both of the latter types allow more interactivity but
I tend to only focus on the last type now as they are
much easier to handle.
Teachers most commonly use these animations by
incorporating them into their teaching periods as illustrations of concepts, etc. The animations can be
displayed via a computer output onto a large screen
TV or monitor or displayed on a screen via a data
projector. However, because of their ability to be
used by most common web browsers, these animations can also be used by students directly using any
internet-capable browser. This can be set as class or
individual work at school, or as homework and can
be targeted towards students who missed some work
or need some revision. The easiest method of using
these animations for individual student use is to include the url addresses in a word document (perhaps
with some accompanying background, instructions
or questions) or to incorporate them as links (or the
actual files) on a school intranet site.
How to locate animations
Use a search engine such as www.google.com and
use key words relating to the specific topic of interest, e.g., +Chemistry +“Periodic Table” +Elements
and also include words such as +animation or +simulation. If looking specifically for a type of animation you can include words like +Flash or +Applet
or even use the suffixes on the files, e.g., .swf, .dcr,
.jar, .class, etc.
Sometimes a link will take you to an index page of
animations that will provide urls for a number of
other related animations. Examples of such sites are
given in the lists of addresses in the Appendix.
Once located, bookmark the page site that hosts it so
that you can return to it later or insert the url into a
word document (such as this) or as a link onto your
school Intranet so that you can quickly return to it.
Health warning – this can get addictive ( I currently
have access to close to 20,000 chemistry animations
-needless to say, I use only a tiny fraction of the best
examples of these!) so my advice is to set up a classification system (e.g., by topic or by achievement
standard) before you start.

Saving Flash Animations from the Internet to store and play locally (for Internet Explorer users)
To avoid the frustration when returning to a site
some months or a year later to find it no longer exists, it is possible to save a Flash animation to your
local hard drive and play it directly from your own
computer or network. This also eliminates the access speed problem for schools which have limited
external bandwidth capability. However, this has
copyright implications and attempts should be made
to gain approval from the site’s author or at the very
least the source site should be acknowledged. Downloading from commercial sites or those with specific
notices forbidding copying of material is obviously
not acceptable.
The instructions that follow are for downloading
Flash files (.swf, .dir, .dcr and .dxr file types) using
Internet Explorer on a Windows platform and would
need appropriate modification for other combinations.
1. Go to Start/Control Panel/Folder Options/View
and tick Show Hidden Files and Folders and untick the Hide protected operating system files.
2. Go to C:\Documents and Settings\Username\Local Settings, and
3. Right Click on Temporary Internet Files Folder
and create a shortcut of this folder on to your
desktop. Once you have this shortcut you can
reset the preferences set in step 1 above.
4. Open Internet Explorer and Google “Flash animation topic” where topic could be titration
curve etc. Open one of the found pages. If you
like the animation and want to save it, leave the
web page open and go to your Temporary internet Files Folder and locate near the bottom of
the list any file that ends in .swf (or sometimes
.dir or .dcr). Click on this file and CtrlC to copy
it. Open the folder you want to store it in (e.g.,
K:\Science\ScienceAnimations\Chemistry\
AtomicStructure) and Ctrl V to save it into the
folder. You will find the name of the file has an
extra [1] inserted into it which is best to remove
manually from the name.
5. To run the animation at any time in the future just
go to where you have saved it, double click on
the specific file you want and it will automatically open and run in your default browser, e.g.,
Internet Explorer. Note: The very first time you
play an animation of a new type such as a .dir
file you may get a prompt box asking what the
computer should use to open this file. Choose
browser from list and select internet Explorer
18
and tick the box that says “Always use to open
this type of file” and it will always work for any
animation in the future.
6. Return to Google and choose next possibility
on list or do new search. Repeat #4. Note you
will need to refresh the Temporary internet Files
Folder to show the new animation just loaded.
You can use the Up and Back folder option icons
to do this.
Saving animations for Mozilla users:
Because the above process can be a little tedious, if
instead of using IE you use Firefox as your browser,
you can download an add-on extension that will allow you to automatically download any embedded
flash files at the click of a button. (Go to Tools tab
and select add-ons and click on Get Extensions and
search as required).
I use “Download embedded” which can be found
at
https://addons.mozilla.org/en-US/firefox/addon/1993
You can also get helpers that will automatically
download video files from streaming sites such as
YouTube, although these are downloaded as a .flv
file which will then need to be converted into a file
format such as .avi or .mov or .qt which is then playable by Media player or QuickTime respectively).
A free piece of software that will do this conversion
is called “Free flv to avi converter” which is available from http://www.nbxsoft.com/files/flvconverter.
exe
If you want to explore what is available as podcasts
you can search the iTunes store either under the Podcast category or the new iTunes U category which is
podcasts made available to students from tertiary institutes. Some are audio only, others are video, e.g.,
for senior chemistry search under iTunes U for the
“Chemistry Comes Alive” series by the Chemical
Education Digital Library. (Many others are appallingly boring!)
Podcasts can also include PowerPoint presentations,
e.g., search under podcasts for “The Periodic Law
Onscreen Tutorial” by Eagle Chemistry.

How to insert Director files (.dcr) into
Powerpoints
7. On the Alphabetic tab, click the Movie property.
Go to http://office.microsoft.com/en-us/powerpoint/
HA011168811033.aspx (details in the Appendix).
8. In the value column (the blank cell next to Movie), type the full drive path including the file
name (for example, C\:My Documents\MyFile.
swf) or Uniform Resource Locator (URL) to the
Flash file that you want to play.
Appendix
A - How to play a Macromedia Flash
animation in PowerPoint for Microsoft
Office PowerPoint 2002-03
If you have an animated graphic that was created
with Macromedia Flash and saved as a Shockwave
file (.swf file extension), you should be able to play
it in a PowerPoint presentation using a specific ActiveX control and the Macromedia Flash Player. To
run the Flash file, you add an ActiveX control to
the PowerPoint slide and create a link from it to the
Flash file. You also have the option of embedding
the file in the presentation.
Important
• The ActiveX control, called Shockwave Flash
Object, must be “registered” on your computer
for you to play the Flash file within PowerPoint.
If it is registered, it will appear in the list of controls opened from the Control Toolbox (detailed
in the steps below). If it is not registered, download the latest version of the Macromedia Flash
Player from the Macromedia Web site; this will
register the control on your computer.
• Older versions of the Shockwave Flash Object
may be registered on your computer. To guarantee that complex animations run properly, we
recommend that you install the latest version of
the Macromedia Flash Player.
To play a Flash file in your presentation, follow
these steps:
1. Install the Macromedia Flash Player on your
computer.
2. In normal view in PowerPoint, display the slide
on which you want to play the animation.
3. On the View menu, point to Toolbars, and then
click Control Toolbox.
4. In the Control Toolbox, click More Controls
(the button with the hammer and wrench icon).
5. In the list, scroll down and click Shockwave
Flash Object, then drag on the slide to draw the
control. You can resize the control at any point
by dragging the sizing handles if you need to adjust it to the size of the animation.
6. Right-click the Shockwave Flash Object, and
then click Properties.
9. To set specific options for how the animation
plays, do the following, and when you’re done,
close the Properties dialog box:
10. Make sure the Playing property is set to True.
This plays the file automatically when the slide
is displayed. If the Flash file has a Start/Rewind
control built into it, the Playing setting can be
set to False.
11. If you don’t want the animation to play repeatedly, in the Loop property, select False (click the
cell to get a down arrow, click the arrow, and
select False).
12. To embed the Flash file so you can pass this
presentation on to others, in the EmbedMovie
property, click True. (In order for the Flash file
to run, however, the Shockwave Flash Object
control must be registered on any computer that
runs this presentation.).
13. To run the animation: With the slide displayed in
normal view, click the Slide Show button in the
lower left of the PowerPoint window (or press
F5, or, on the Slide Show menu, click View
Show).
14. To exit the slide show and return to normal view,
press ESC.
B - How to insert Director files into PowerPoint 2002-03 presentations
Both PowerPoint and Director have complex and
numerous file formats. Director formats include
.dir, .dxr, .exe., and .dcr files; PowerPoint formats
include .ppt, .pot, .pps, .html, and .mht files (the last
two for Web presentations).
The editing format in Director is a .dir file. After you
have a complete project, you can choose to save it
as a protected .dxr file, create a stand-alone .exe file
(or projector, in Director parlance), or convert to
the ShockWave Director format, a .dcr file, which is
used mainly to deliver content online.
The default format for PowerPoint is the .ppt file.
A .pot file is a PowerPoint Design Template format,
and a .pps file is the PowerPoint Show extension.
(The .pps extension is actually the same format as
.ppt, but it tells PowerPoint to open the file as a slide
show, instead of in editing view.) In addition, since
19
Chemistry Eduction in New Zealand August 2010
the 2000 version, PowerPoint has an .html and .mht
file format, rendered satisfactorily by Microsoft Internet Explorer 5.0 or later.
1. Open or create a new PowerPoint presentation,
and then save it in the same folder as your .dcr
file.
Finally, third-party tools enable you to export an
entire PowerPoint presentation to the Flash .swf
file format; and you can export presentations to the
QuickTime .mov file format by using PowerPoint on
the Macintosh. Both .swf and .mov files can be imported straightaway into Director.
2. On the View menu, point to Toolbars, and then
click Control Toolbox to open the Control toolbar.
The .dcr file format: For incorporating
Director content into PowerPoint
Director uses the .dcr file format to deliver Web content. It’s similar to - although more advanced than
- the other Macromedia Web file format, .swf, which
belongs to its Flash program.
The only way to incorporate Director content into
PowerPoint is to use .dcr files from Director. To
convert your Director content to the .dcr file format,
you can refer to your Director manual or Help menu.
Also, the Macromedia Web site includes an excellent introduction to Shockwave Publishing.
Make sure that you have the Shockwave
ActiveX Control
Many systems that have the Shockwave Flash control installed also have another, similar control installed as well. This is actually the Macromedia Director Shockwave control, known as the Shockwave
ActiveX® Control.
The prerequisites and techniques for using both controls are strikingly similar—all you need to realize is
that the Director control is separate from the Flash
control.
To install or update your Director control, visit the
Adobe Shockwave site.
After you’ve installed the control, you can preview
any .dcr file just by dragging it from Windows® Explorer into an open Internet Explorer window.
Insert Director content into PowerPoint
Before you begin inserting Director .dcr file content
into PowerPoint, save the .dcr file in the same folder
as the actual PowerPoint .ppt file. This way, you will
not have to enter the full path later.
20
3. Near the bottom of the Control toolbar, click
the More Controls button, represented by a
hammer and a wrench, to see a list of available
ActiveX controls.
4. In the list, click the Shockwave ActiveX option.
The pointer becomes a cross-hair.
5. Draw a rectangle anywhere on the screen.
6. Don’t bother about the size and location now;
you’ll take care of that later. Your rectangle is
invisible because it’s only a placeholder. If you
haven’t clicked anywhere, you’ll see that it’s
surrounded by eight sizing handles.
7. Right-click anywhere inside the rectangle, and
then click Properties on the shortcut menu.
8. In the Properties dialog box, click the blank cell
next to the SRC option, and then type the name
of your .dcr file.
9. You don’t need to enter any path because the .dcr
file is saved in the same folder as the presentation.
10.Note: Unfortunately, the control automatically
picks up the full path of the file, so you will have
to edit the path if you change folders, drives, or
computers. You’ll notice that the control does
pick up the actual length and width coordinates
of your .dcr file in the Properties dialog box, although these are not reflected on the actual slide.
11.Position and resize the control as required on the
actual slide.
12.You’re done! You may want to try out the many
other options included in the Properties dialog
box.
The following sections provide a small sample of url
addresses for a varied sample of animations.
Note: As it is an old list, some of the urls of course
may no longer exist at these addresses.
