Science teachers, lighten your load in the classroom and bring out the very best in your students with the incredible Shedding Light series.

We produce…

  • the highest-quality video resources;
  • a free online text book (just navigate to whichever topic you’re doing);
  • outstanding question sheets that accompany each video and;
  • awesome practical activities.

In combination, our resources make it easier for teachers to teach and easier for students to learn!

Teaching, at its most basic level, involves two equally important parts:

Part 1,
•  giving instructions,
•  explaining concepts,
•  demonstrating a skill etc.
Part 2,
guiding students as they
• try out,
• practise,
• acquire, and
• master new skills.

Our “Shedding Light” video series brilliantly help teachers take care of Part 1, and our student activity sheets, online text book, and practical activities brilliantly allow students to reach their full potential during Part 2.

Using video programs as a core part of teaching (rather than an afterthought or just for revision) is undeniably effective.


  • if your printed text book is a little too dry and uninspiring (not to mention wordy), and
  • if you have a lot of students who are visual learners and who learn best when they see animations and demonstrations, and
  • if you are tired of trying to find good online videos that are pitched at the right level and that cover the content that you need covering…

then our Shedding Light resources are for you.

Here are the seven Shedding Light series that we have produced so far.
Each series covers an entire unit of work.

The 8-part Shedding Light on Atoms series
The 8-part Shedding Light on Motion series
The 6-part Shedding Light on Light series
The 3-part Shedding Light on Energy series
The 6-part Shedding Light on Heat series
The 5-part Shedding Light on the Sun and Earth series
The 3-part Shedding Light on Electricity series

We invite you therefore to

  • browse our videos,
  • download our worksheets and prac sheets, and
  • read each program’s transcript

so that you can see for yourself what a difference they will make in your classroom.

The Shedding Light series are available to schools and institutions that have
Films on Demand, and
SAFARI Montage.
Just login and search for whatever video you want.

Schools without streaming services can order DVDs.

Individual programs can be ordered on each program’s dedicated page, but huge discounts apply if you order a whole series.
Even bigger discounts apply if you order 2 or more series.

Just visit the Orders page for details.


LEM has finally gone digital.
The Shedding Light on Energy series can now be purchased in digital format.
Stream anywhere,
stream anytime,
stream on any device…
on Vimeo!!

Simply go to https://vimeo.com/ondemand/sheddinglightonenergy,
sign up to Vimeo,
and then purchase.
DVDs are great and a lot of schools are still using them, but digital access is so much more convenient!!
So if you want to get hold of the Shedding Light on Energy series, head on over to Vimeo now!!
And don’t forget to sign up for notifications so that you can stay informed about new releases and special offers!!
We’ll be adding more programs to Vimeo in the coming weeks.

Every program comes with

  • outstanding student activity sheets so your students can immediately put what they’re learning into action;
  • answers to all the questions, which makes your life easier;
  • fully annotated transcripts that act as a text book for when students want to, for example, consult tables or read definitions;

In addition, all of our programs are broken up into small sections that are between 5 and 10 minutes long, which makes your lesson planning really easy.

For example, see our Heat Transfer page.

Sure you can find educational videos on video-sharing sites, but education is not just showing kids things, it’s more about getting kids to put what they’ve learned into practice. You would never show kids a video about how to play a guitar and then not actually give them a guitar to play!

Thousands of schools are now using our resources to bring out the best in their students.
And why is that?
Because they make teaching and learning much easier for everyone!

So lighten your load in the classroom and get hold of one or more Shedding Light series today!

Dear Spiro,
Thanks for the great resources on ClickView and your website.
I’ve used the “Periodic Table Table” with a year 8 class and it went really well.
Even better has been the “Shedding Light on Motion” series. Episode 6 on Newton’s First Law was great for my class to get a grip on inertia. The other videos and worksheets have been great too.
Warm regards,
P. Whitely | Teacher – Science & Religious Education
Our Lady of Sion College, Box Hill

Who We Are
Liacos Educational Media is made up of Yours Truly, Spiro Liacos, and my wife Georgina Liacos. We both work part-time as teachers, but I am very proud to say that, thanks to the thousands of teachers who liked what they saw when they came to our website, we have also become one of the premier producers of science-related educational materials in Australia.
I don’t consider our Shedding Light videos to be our “products” because I use them all with my own students. My colleagues all use them extensively as well, and my students (both the ones I actually teach and the other students at my school) are constantly telling me how much they enjoy watching them. They like the fact that every concept is explained in detail and that we also explain how the Science relates to them and to the world that they live in.
Using the Shedding Light videos in my classrooms makes it far easier to teach the topics of Motion, Chemistry, Light, Energy, and Heat and I have seen the levels of engagement and of achievement both really soar.
You can read more about us on our About Us page, but you’re probably better off previewing one or more of our Shedding Light series, because, ultimately, we just want to help students learn Science more effectively. And I’m guessing you do too.

I typically use the Shedding Light programs in three different ways.

Method 1: Regularly Pausing.
After distributing the worksheets, I pause the video regularly as the answers to the questions on the worksheet come up.

Method 2: Video and Online Text Book Combination.
I will often show a few sections of the program to my students (and occasionally the whole program) and then ask them to answer the worksheet questions by referring back to what I call the online text book on the LEM website. The online text book is basically a transcript of the program with screen shots. (Every Shedding Light program has its own page.) This allows the students to read over the material that they have already seen when they watched the video.

Method 3: Whiteboard Summaries.
This method is similar to Method 2. I sometimes show an entire program to my students but pause occasionally to write brief summary notes on the board. I then distribute the worksheet. The students can then use the LEM website and the summaries to answer the questions. For example, I recently showed the entire Shedding Light on Heat Episode 1: Temperature program to my students, but paused the video occasionally to write the following notes on the board:
Heat is a form of energy.
Temperature scales allow us to compare the temperature of different things. Eg. Human Body Temperature: 37°C.
When an object is hot, the atoms that make it up move and vibrate quickly. When an object is cold, the atoms that make it up move and vibrate slowly.
The unit for energy is the joule (J).
If 1 kg of water absorbs 4,200 J of energy, it’s temperature will increase by 1°C.

Which Method is Best?
I’m not sure which method is best. I have surveyed my students over the past few years and there’s no clear-cut winner. It’s probably good to vary it a little anyway. However, they all report that they learn a lot more from the videos than they do from the school’s prescribed text book. I think students (and adults) learn best when they see actual video and animations rather than static pictures from a text book.

Feel free to let us know how you use the Shedding Light programs in your class (including, if you’re a student, how your teacher uses the Shedding Light programs).

Teaching an entire unit using videos is a real game changer for teachers and students. Though text books and PowerPoints are fine, videos give students a much better understanding of the content being covered. So browse our website and then jump onto
