They say the sky is the limit but Colo Vale Public School students are looking to space.
The One Giant Leap Australia Foundation is sending native golden wattle seeds to the International Space Station in early December.
In collaboration with the Japan Aerospace Exploration Agency and with support from the Australian Space Agency, the seeds will live in space for six months and will return to Australia in time for Science Week 2021.
Colo Vale Public School was among 150 schools, scout groups and Australian Air Force Cadets selected for the historic initiative.
A panel judged applications from across Australia, which involved a 200-word statement and a short video.
Year six students and environment committee members Takoa and Nash wished the astronauts well on their journey into space.
"Good luck and don't kill our seeds," Nash said.
"Keep our seeds safe," Takoa said.
The students also thanked Wariapendi Native Plant Nursery employees for their support and advice.
Colo Vale Public School entered a submission to showcase students' passion for the environment and surprise principal Nina Culleton.
The school's submission was titled 'From Little Things, Big Things Grow'.
Chosen schools around Australia have arranged to receive wattle seeds that have flown to space as well as seeds that have not.
The seeds are from the same seed lot. Students will germinate and grow their seeds then record the data.
Data will be uploaded to the 'What'll happen to the wattle?' mobile phone app.
Throughout the programme, One Giant Leap Australia Foundation will run teleconferences and provide educational support to participating groups.
The 12-month to two year project will result in the creation of a nationwide map identifying the location of Australia's 'space wattle' trees.
