Agricultural Literacy Curriculum Matrix

Students identify the importance of plants to human life by surveying their home and neighborhood for plant products used for medicine, aesthetics, fuel products, fiber, and food. Grades 9-12

crop regions: certain crops grow in specific regions of the United States based on influencing environmental factors (frost free periods, mean average temperature and rainfall)

hardiness zone: a geographically-defined zone in which a specific category of plant life is capable of growing, as defined by temperature hardiness, or ability to withstand the minimum temperatures of the zone

Plants are vital to all life on Earth. They mean survival. Plants are the base of food for all humans and animals. They can harvest energy from the sun and exchange gas. (Plants use carbon dioxide from the air and convert it into oxygen.) Plants use the energy from sunlight to convert raw materials from the Earth into carbohydrates, fats, and oils. Humans depend on plant materials for food, feed for livestock, fiber, fuel, medicine, aesthetic value, and much more.

Plants are affected by environmental factors, including frost-free periods or growing season, mean average temperature or growing degree days, and rainfall. These factors create unique growing conditions across the United States and throughout the world.

1. Ask student to think about the many times a day they touch or eat things that come from plant materials. Our world consists of an unimaginable number of products originating with plants. Students are likely touching several as they sit in a chair and take notes in their notebooks. Plants are a major part of daily life in several forms.
2. As a class, make a list of plant products found in the classroom.
3. Inform students that in this lesson they will:
   • Identify why plants are critical for all life on Earth.
   • List plant products found in your everyday world.
   • Explain why certain plants are grown in certain regions of the United States.
   • Compare and contrast the growing conditions in various areas of the country.

Summary of Content and Teaching Strategies

1. Present and discuss Teacher Material- Surrounded by Plants. Have students brainstorm examples for each of the ways humans use plant material.
2. Distribute a copy of Handout A- Surrounded by Plants to each student. Review the handout and answer any questions. Have students complete the triangle in Figure 1. In Part 2 of the activity, students will research the common growing regions for one crop from each category in Figure 1. The directions instruct students to print off a United States map from the 50states.com website. Using this map, students shade growth regions using colored pencils for one crop from each use category. Use a different color for each crop and label the colors in a map legend. Students must incorporate the "TODALS" (title, orientation, date, author, legend and scale) map basics into the map they create.
   • For forestry products, the USDA Forest Service database is provided.
   • Students will need to research medicinal crops separately. The following are common medicinal crops to consider providing to students who need assistance in this category:
     • aloe
     • aspirin
     • castor bean
     • Echinacea
     • ginkgo
     • hemp
     • Saint John’s Wort
3. Once Part 2 is completed, students access hardiness zone and precipitation websites to determine the climate correlations to the production regions shaded on their maps. This activity provides an understanding of why certain crops are grown in certain regions due to their dependence upon climate conditions.
