    potato plant and parts of a potato.
   This activity also makes you aware of the
    students knowledge of the subject.
   Students could each grow a plant with a
    potato in water to see the plant and its

Activity 2
Potato Soup
   The students would be able to
    learn measuring and the process
    involved in making potato soup.
   Students would be able to try a
    product they have made from the
    plant they would be studying.
   They may be tasting a new food
   This could also allow for discussion
    of all the varieties of potatoes.

    potatoes change in different
    solutions.
   Allows students to see how the
    texture and form of potatoes
    change when introduced to other
    elements.

   Iodine changes color to blue or
    black.
   Have students explain how this
    could be important or how they
