Tomatosphere - Mission to Mars An Educational Outreach Project for Primary and Secondary Schools
Bibliographic record
Abstract
The concept for Tomatosphere originated in late 1999 and the project held its first formal meeting on February 7, 2000. The project was formally activated when 200,000 Heinz tomato seeds went into space on November 30, 2000, with Canadian astronaut, Dr. Marc Garneau. The seeds were part of an experiment designed to test the effects of short- term space travel on seed germination and interaction with new techniques designed to enhance germination rates. An equal number of seeds stayed behind on Earth and the two lots, space-flown and Earth-bound, were further sub-divided into two treatments using new Infra Red and Red light technology developed at the University of Guelph. The resulting four treatments were packaged and sent to almost 2700 classrooms across Canada, along with posters and a teacher's guide matched to the Pan-Canadian Protocol for Collaboration on School Curriculum, a framework of Science Learning Outcomes developed by the Council of Ministers of Education, Canada. The emphasis for the curriculum connections was from grade 3 (plants and soil) to grade six (space). The project met with an overwhelming response from educators and students. As such, in 2003, the project expanded to involve more than 5 000 classrooms across Canada; the scope of the project was also expanded from the original grade 3 - 6 focus to include grades 8 - 10. The scope of the curriculum in grades 8 - 10 allows for the incorporation of several objectives relative to the ISS mission objectives, the overall concept of humans in space, and the application of knowledge from space programs to the well-being of humankind on Earth.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
