Planning Index: Plants for Food & Fibre | Print |

Grade 7 Science Unit Plan
Unit B - Plants for Food & Fibre
(emphasis on Social and Environmental context)

Grade 7 Unit Overview (Alberta)
Humans have always depended on plants as a source of food and fibre, and to meet a variety of other needs. To better meet these needs, technologies have been developed for selecting and breeding productive varieties, and to maximize their growth by modifying growing environments. (Plant Biotechnology Resource) Long-term sustainability requires that we become aware of the practices we use, and examine impacts of these practices on the larger environment. Alberta Environment (Website)

Concepts Covered and Developed through Instruction

What do the students already know?

What are plants used for?
How does technology help us use plants for many purposes?

What must they Learn?

Processes which transform plants into food and fibre products in a sustainable way.
