Direct ISS science
Open registration
Tomatosphere
Students grow two groups of tomato seeds without knowing which
group was exposed to space conditions. They measure germination and
growth, then submit results online to support research into plants,
food systems, and long-duration space travel.
CSA classroom activities
Resources open
Junior Astronauts - CSA
The CSA Junior Astronauts activity bank gives schools ready-made
lessons in science and technology, fitness and nutrition, and
teamwork. ISS-linked activities include living in space, food,
false alarms, working in space, and environmental monitoring.
Coding on the ISS
Annual / seasonal
Astro Pi Challenge
Students write code for Astro Pi computers aboard the ISS. Mission
Zero is beginner-friendly; Mission Space Lab lets teams design a
scientific experiment, with selected projects run on the station.
Canadian students are eligible through Canada's ESA cooperation.
Design challenge
Resource pack open
Little Inventors - Inventions for Space
Students imagine inventions that could make astronauts' lives in
space easier or more fun. The original Canadian submission
challenge has ended, but the NSERC/CSA classroom resource pack is
still available for schools to run the activity.
Student-designed experiment
Mission 22 planning
Student Spaceflight Experiments Program (SSEP)
School communities design microgravity experiments that fit within
a mini-lab compatible with ISS experiment racks. A local review
process selects a flight experiment. Mission 22 lists an
experiment design phase in fall 2026 and ISS flight in spring 2027.
ISS data analysis
Free enrollment
Orion's Quest
Students act as classroom research assistants for ISS
investigations. Missions use downlinked photos, video, and data
from station experiments so students can analyze findings and send
results back to scientists.
Student research payloads
Global provider
DreamUp
DreamUp offers space-based education and student research pathways
from classroom curriculum to experiments and code that can operate
on ISS hardware. Voyager describes DreamUp as serving students
globally and having brought hundreds of student research payloads
to the station.
ISS plant science
Kit / challenge
Magnitude.io ExoLab
Students grow plants in a classroom or home ExoLab while following
a related ISS experiment. They compare ground data with station
imagery and sensor data to investigate plant biology, microgravity,
legumes, and food sustainability.
ISS experiment platform
Global K-12
Quest for Space - Quest for Excellence
Students run or design experiments that compare classroom data
with experiments on the ISS. Advanced teams can conceptualize,
document, code, and prepare experiments for NASA approval and ISS
operation.
ISS classroom resource
Free resource
Story Time From Space
Astronauts aboard the ISS read children's books and demonstrate
related science concepts. It is not a flight experiment submission
program, but it is a free ISS-based classroom activity available
to Quebec students online.
Live ISS contact
Apply by region
ARISS - Amateur Radio on the ISS
Schools prepare a STEM and amateur radio project, then apply for a
scheduled direct, telebridge, or virtual telebridge contact with an
ISS crew member. Students ask questions live while learning radio
science, satellite communication, and life in orbit.
ISS Earth imaging
Mission-based
Sally Ride EarthKAM
During EarthKAM missions, teachers register students to request
images of Earth from a camera on the ISS. Students choose targets,
submit image requests, then analyze the images they receive.
Health and space science
Open worldwide
Mission X - Train Like an Astronaut
Teams complete physical and scientific activities inspired by
astronaut training and submit progress for the Walk to the Moon
Challenge. The 2025-2026 challenge is open worldwide and runs
through August 14, 2026.
Canadian design challenge
Resources open
Space Brain Hack - CSA
Students propose solutions for real space-sector challenges,
including astronaut mental health and isolation, food production
for long missions, and sustainable satellite missions. It is a good
Canadian bridge into ISS life-support and exploration topics.

CSA Activities and Experiments
This is the broad Canadian classroom hub for ISS, space food,
robotics, astronaut health, Earth observation, Moon, and Gateway
activities. For Quebec teachers, it is the easiest place to find
French-ready classroom materials and grade-level alignment.
