Plants for Food and Fibre
Overview: 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 plant varieties and for maximizing their growth by modifying growing environments. Long-term sustainability requires an awareness of the practices humans use and an examination of the impacts of these practices on the larger environment.
Focusing Questions: How do we produce useful plant products? What techniques do we use, what knowledge are these techniques based on, and how do we apply these techniques in a sustainable way?
Key Concepts
The following concepts are developed in this unit and may also be addressed in other units at other grade levels. The intended level and scope of treatment is defined by the outcomes below.
− needs and uses of plants − plant propagation and reproduction − life processes and structure of plants
− fertilizers and soil nutrients − chemical and biological controls − plant varieties
− selective breeding − monocultures − resource management
− sustainability
Outcomes
Students will:
1. Investigate plant uses; and identify links among needs, technologies, products and impacts
2. Investigate life processes and structures of plants, and needs of plants in a local environment
3. Analyze plant environments
4. Identify and interpret relationships among human needs, technologies, environments, and the culture and use of living things as sources of food and fibre
