Videos
Each day of the field trip, curriculum-rich videos are made which take students right up close to the action.
LEARNZ videos are in mp4 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).
