Each day of the field trip, curriculum-rich videos are made which take students right up close to the action.

Starting in 2012, LEARNZ videos are in mp4 format (rather than in wmv format) and are able to be played on almost all computers. If the videos don't play we recommend you download and install appropriate software such as Quicktime 7 (or better) or Windows Media Player (however most computers already have either or both of these installed).

Some simple instructions

We suggest if your connection to the Internet is slow or if you intend playing any video more than once, that you download the file to your local machine or network

  • PC users - Internet Explorer left-click on a link and follow prompt to Save, for other browsers right-click on a link and "Save Link As"
  • Mac users - hold down Ctrl and click on a link then "Download Linked File"
  • Once downloaded, double-click the file to play it or open your media player first, click File...Open and navigate to the file
