Wimmera primary schools came together on Wednesday for a day of discovery with a visit from the Commonwealth Scientific and Industrial Research Organisation.
The day at Laharum Primary School included junior students from Haven and Natimuk primary schools.
Laharum principal Jane McLean said CSIRO's activities were focused around physics.
"We had an activity on the seasons and two on forces," she said.
"One was on simple machines and we had a group activity on designing a parachute against the force of gravity."
CSIRO also took its star lab a portable planetarium to the day.
Mrs McLean said students were enthusiastic about the activities.
"They were absolutely captivated because it was hands-on," she said.
"They were constantly making things and testing things.
"They were all engaged and I think the staff were too."
Mrs McLean said the schools were fortunate to have CSIRO visit, as such events were coming to an end due to funding cuts.
The day was one of four each year when the schools meet.
Mrs McLean said the day established important links for students at smaller schools.
"It's a wonderful experience for the students as they get to know fellow peers in similar schools," she said.
