Primary school students were engaged in all aspects of Science, Technology, Engineering and Mathematics (STEM) at Edward John Eyre High School's STEM Expo on Thursday.
The expo featured a variety of activities based on the core aspects of STEM run by high school students between years 8 and 11.
Those included using Virtual Reality headsets, laser cutting, drones, remote control cars, K'NEX blocks, escape rooms, and much more.
Whyalla High School STEM Coordinator David Fargher said the aim of the expo was to give primary school students a STEM experience they may not have had previously.
"We want to give them a chance to use their skills in problem solving, critical and creative thinking, and digital literacy," he said.
Mr Fargher said the feedback from students about the day had been very positive.
"The students are loving it...a majority of them walk in with smiles and they walk out with even bigger ones," he said.
"All the teachers are really positive about it and all the staff that have come over have been excellent. The school groups that have come through have had a fantastic time.
"A majority of the Whyalla High School students have experienced STEM expos in the past, enjoyed it, and have come back to present it to the primary school students because they know how worthwhile it actually is."
