Welcome to Tomatosphere!

Over the past ten years, Tomatosphere has evolved into a regular component of the curriculum for more than 13,700 classrooms in Canada and the United States. The Tomatosphere Project Team will continue offering this stellar learning opportunity through to 2014. The project currently has 600 000 tomato seeds on board the International Space Station.

Some of the seeds for 2012 have been primed. This process is outlined in the Teacher's Guide – Seed Treatment for 2012. Information about the priming process is included here. The second set of seeds is the control group.

The planet MarsThe basic experiment of Tomatosphere will remain for the this 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. Data collection for this year and for 2013 has been changed. Teachers will need to examine this area before proceeding.

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, 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 Canadian scientists to understand some of the issues related to long-term space travel.

Mariner on the planet MarsOptional units are also available for grade 6 and 9, dealing with weather, nutrition and life on Mars.

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 involves them in providing assistance for 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:
