Youngsters from the school in Middle Swan were among 1600 students selected to receive an award recognising their ability and passion for science-based learning activities.
The two top science students in Year 6 from participating schools received a Woodside Scitech Science Award last month.
More than 820 primary schools across the state registered for the awards in 2015, up from 795 last year.
Scitech professional learning manager Michael Peter said more schools were tackling problems of science, technology, engineering and maths (STEM) disengagement among students.
“We hope that through this award, students will be encouraged to continue developing their science investigation skills in high school and beyond and maybe go on to achieve great things,” Mr Peter said.
Nanobiology researcher and Australian hockey player Tristan Clemons and Woodside innovation capability vice-president Brian Haggerty addressed students on the importance of STEM studies.
