Usually up to 100.  This will depend on the venue but smaller is definitely better as students are closer to the action and we will have a better interaction.   We do reserve the right to limit the number of students for safety reasons.  For Science Nights and special events the attendee number can be higher. 

Yes. The minimum fee per visit is the cost equivalent of two sessions (2 x $530 plus GST).  If you are from a small school (less than 70 students in the cohort) then please try to find another Year group to take up the second session.  There may be a small fee depending on the selection of their topic.  Please discuss with your colleagues.

We have a new item on offer!  Our Science in a Box, is a box packed with 7 science toys that will engage and teach while the students are having fun.  The content is selected for students 6 to 12 years and is offered at a price so each one can have his own box.  

Students take their boxes home as it has full instructions and scientific-play ideas so the learning can be extended.  All drafted by Prof Bunsen Science.
