Students at Caroline Chisholm Catholic College were walking on clouds last week.
As part of the school’s Science Week activities, a year 11 chemistry class used dry ice to turn a classroom into a cloud.
College science head of learning Marnie Bates said it was an opportunity to have some fun.
“The idea is to give students something really fun to celebrate science,” she said.
“The students loved the affect the dry ice has.”
Ms Bates said she hoped the experiment would open the students eyes to bigger things.
“We want students to be encouraged to get into science fields because there’s so many careers available,” she said.
While the visual result of the experiment was startling, Ms Bates said the science behind it is simple.
“The science behind this is sublimation, which is when we have a solid going directly to a gas with no liquid phase,” she said.
“The kids can come in and walk on ice and enjoy themselves in celebration of Science Week.”
The school capped of its Science Week festivities with a year seven science fair.
“Our students worked on a long term project investigating something they’d always wondered about science,” Ms Bates said.
“Then we had a night where they brought their parents along and spoke to the public about their work.”
