Welcome to Tomatosphere!

Over the past eight years, Tomatosphere has evolved into a regular component of the curriculum for more than 11 000 classrooms in Canada and the United States. The Tomatosphere Project Team will continue offering this stellar learning opportunity for 2010 and beyond.

Seeds for 2010 were on board the International Space Station, with CSA Astronaut, Dr. Robert Thirsk. They were taken into space by Julie Payette and returned to Earth later in the fall of 2009.

TEACHERS WISHING TO PARTICIPATE IN 2010 ARE ENCOURAGED TO REGISTER EARLY SINCE THE AVAILABILITY OF SEEDS IS LIMITED TO THE 13 000 SETS THAT WE HAVE DEVELOPED USING THE SEEDS FROM THE INTERNATIONAL SPACE STATION.

The basic experiment of Tomatosphere will remain for the two year; a 'blind test' in which you and your students will not know the treatment of the seeds until completion of the germination process and submission of results. Students will learn how to conduct a scientific experiment and compare the germination rates of the seeds. They may also report on the growth and development of their plants... and may be inspired to pursue further education in science and technology.

Watching these seeds grow will encourage classroom dialogue about the elements of life support requirements for space missions - food, water, oxygen and the need to consume carbon dioxide exhaled by crewmembers. Traveling to and from Mars - the closest planet to Earth - could take almost three years. It's imperative to know how to grow food for the journey there, the stay on Mars and the return journey. The results from your science experiments will help scientists to understand some of the issues related to long-term space travel.

Tomatoes are practical and valuable plants for space applications. They provide wholesome nourishment, as well as purified water through evaporation from their leaves. Today's students are the plant specialists, space scientists and Mars explorers of the future! The technical support staff and even the astronauts for future space travel may be in your classroom today! You and your students will not be disappointed in being part of a REAL science project that will be of assistance to future space travel.


The partners in Tomatosphere have developed new optional units for teachers and students - new components that are science-related but also linked to other areas in the curriculum:
