    Should we eat strawberries in
            the winter?

•   When will different parts of the world
    be able to grow strawberries?
•   When can we buy them in the shops?
•   Look at the fruit in the shops now.
•   Where do they come from?
   Where does the fruit on our
  supermarket shelf come from?

• Look at the range of fruit in the
  classroom and note which country they
  are from
• Estimate the distance the fruit has
  travelled using the tables on the next
  slides

    Writing up your case study.
           To start with ..
Why are some strawberries that we eat
being grown abroad? What factors are going
to be important for growing delicious
strawberries. Use your scientific knowledge
and understanding of how plants make their
own food.
When will different parts of the world be
able to grow strawberries? When can we buy
them in the shops? Look at the fruit in the
shops now. Where do they come from?
          Food miles

• Sometimes fruit is transported
  to Britain from countries far
  away. Is this a problem? What
  environmental damage does mass
  transport cause?
• Use information from the internet and
  books to find out about the damage
  caused by transporting fruit over
  these distances.
•    Don’t forget to reference any
  information.
•    See if you can get some actual
  evidence (e.g. data, tables, graphs…)
       Arguments against..

• Make an argument against eating
  strawberries in the winter.
• Find some quotes to back up your
  ideas.
• Evaluate this claim. Is your
  information based on evidence or is it
  just opinion.
             Arguments for
• Is there a good reason for transporting
  fruits and vegetables over such great
  distances? Do they taste better? Does it
  help the country they come from?
• Make an argument for eating strawberries
  in the winter.
• Can you find a quote or some data to back
  up your claim?
• Evaluate this claim. Is it based on evidence
  or opinion
• You may want to do a comparison of
  fruits from several different
  countries as shown on the next slide
           Strawberry testing
• You could carry out      Criteria   Comments   Mark
  blind testing of         Mass (g)
