Space Tomatoes Arriving Home
We are at the end of our experiment involving tomatoes and space. Now, I know you are probably wondering what the two have in common. The Canadian Space Agency is involving schools in a very real experiment to test whether or not it is possible for plants to grow food in space – in zero gravity environments. This is the only way we are going to get astronauts to places like Mars as there is not enough space to carry the amount of food needed to reach there and back without being able to grow our own food. 
As part of the experiment, we grew two types of seeds; seeds that have actually been in space – and thus have been exposed to zero gravity – and ordinary seeds. However, we did not know which ones were which as the Agency does not the results to be biased.
Over the past few weeks, we have been watching our plants grow, or not! Students drew and wrote about their tomatoes. To be successful, the tomato plant needed to produce at least 2 leaves. Most of the plants did but there were a couple that did not!
Today was our last observation and conclusion to the experiment. Students took both the x and y tomato plants back to their seats in cups and drew their final observations, as well as recording in words what they saw, felt and smelled. They also wrote some conclusions to questions about the experiment. Finally, it was time to submit the results and see which tomatoes were the seeds that had gone to space. And the space tomatoes were…….
THE Y SEEDS!!!!!

This was very unexpected to the students! Most of them chose the x seeds as being the ones to have been exposed to zero gravity. We all had a lot of fun with growing the seeds. The students were fascinated by the process. Every morning they would gather around the plant trays and see how their plants were doing.
Students also got to take their tomatoes home today so you may be seeing some cups with plants in them. You’re welcome! đ The plants will need to be transferred to a slightly larger container and have some more soil added to them. They can live on a windowsill or other sunny spot until they can be planted outside. You may be able to keep them planted inside but will likely need a larger pot and some way to stabilize the stem as it gets taller. I look forward to hearing whether any tomatoes actually come from the vines!
