Harrop said the trip meant the students would be able to look at physics not available in New Zealand, including the tokamak - a nuclear fusion reactor.
To participate in the hands-on experiments, the students had to study to ensure they were prepared for this part of the trip, Harrop said.
"Some of the learning will be valuable for their NCEA internal and external assessment, and other learning will be a rather large extension for them," she said.
Harrop attended a few workshops at the S'Cool Lab building as part of her trip to CERN last year.
"I was really keen to try and provide the opportunity for students to make their own cloud chamber and be involved in physics educational research," she said.
Otumoetai College student Aria Smart was particularly excited to see the modern science of a nuclear fusion reactor.
"That is present science, it is brand new, groundbreaking even," she said.
"We get to see that up close and it is really exciting. We don't get to see stuff like that in New Zealand because we are nuclear free."
Fellow student Sam Reeder was also excited to gain awareness of science overseas.
"I am looking forward to meeting lots of new scientists and seeing their backgrounds and how they got to where they are today and be inspired by them."
