The roadshow is in its 21st year of operation and, as well as receiving funding from Fonterra, the show is funded by the Ministry of Education Learning Experiences Outside the Classroom programme.
This year the roadshow travelled to more than 90 communities and was visited by 700 schools.
The aim of the roadshow is to give pupils a chance for hands-on learning.
The themes for this year's roadshow are how things work, gravity, investigating life, astronomy, measurement and reflections.
East Gore Primary School deputy principal Dana Turnbull said the roadshow was excellent because pupils could try a wide variety of practical exhibits, all of which were well received.
Roadshow manager Andrew Beale said there were 60 to 65 exhibits at the roadshow.
The roadshow catered for children aged between eight and 13, Mr Beale said.
