Process


You will be working in a group of three. Each of you will have a specific role in the group. The roles are:

The Investigator Scientist

It is your job to answer the question:

What is Tomatosphere?

Go to the Tomatosphere website and watch the video "Tomatoes in Space" - look for it in the sidebar on the right.

While viewing the video, use the worksheet (click here) and record answers to the following questions:
  1. What is Tomatosphere?
  2. Who can participate in Tomatosphere?
  3. Why did the Project Team choose tomatoes for this experiment?
  4. What will the Project Team do with the data collected?
  5. Why don't the astronauts eat packaged food? Why do they need fresh food?

*Hint: Remember to pause the video while you are watching and record your information.

 Now that you have completed your research, please teach the other members of your group about the Tomatosphere project.


The Regulator Scientist

It is your job to answer this question:

What is an experiment and how is it done?


Scientists use the scientific method when they want to do an investigation. The scientific method is a way to ask and answer scientific questions by making observations and doing experiments. The steps of the scientific method are:

  1. Question - Scientists write down what they want to learn.
  2. Hypothesis - After doing research, scientists try to predict the answer to the problem. Another term for hypothesis is "educated guess". This is usually stated like "If I ...(do something) then ... (this will occur)".
  3. Experiment - The fun part! Scientists design a test or procedure to find out if their hypothesis is correct. They write down exactly what must be done for their experiment step by step. It is important for any experiment to be a fair test. A "fair test" occurs when you change only one factor (variable) and keep all other conditions the same.
  4. Observation - Record what happened during the experiment. This is also known as "data collection".
  5. Conclusion - Review the data and check to see if the hypothesis was correct. It is not "bad" if the hypothesis was wrong, because the scientist still discovered something!

 Now that you have finished your research on experiments, download the worksheet (click here) and record your information. 

 Next, please share your information with the other members of your group and teach them about experiments.



The Explorer Scientist

It is your job to answer this question:

Why are scientists doing this experiment?

Go to the Tomatosphere website and watch the video "Tomatoes in Space" - look for it in the sidebar on the right.
While viewing the video, use the worksheet (click here) and record answers to the following questions:

  1. Why is this experiment being done?
  2. What do tomato seeds and astronauts have in common?
  3. What different areas of science are needed to get people to Mars?
  4. Why was Mars chosen as the place to be in space?
  5. How long will it take to get to Mars?
  6. Is there somewhere closer to go?

 Now that you have completed your research, please teach the other members of your group about why the Tomatosphere experiment is being done.

Group Research



Before you begin creating your report and publishing the information you have collected, you need to do a bit more research about conducting the experiment. Go to the links below to find answers to the following questions:

  1. What materials do we need for our experiment?
  2. Where will we keep our germination centre?
  3. When should we plant the seeds?
  4. How do we plant the seeds?
  5. How will we make sure the seeds don't get mixed up?
  6. What is germination?
  7. How do we record the data we collect?

Remember, you are working together on this part of the quest - you only need one worksheet for your group.
