Background – Agricultural Connections

Iowa farmers plant soybeans in late April and May.  They monitor the crops throughout the summer, and sometimes spray insecticides, fungicides, or herbicides to protect the plants from insects, diseases, or weeds.  When the seeds have matured in the fall, the upright plant begins to shrivel and the leaves fall away.  All harvesting is done by machines. Farmers use combines that cut the stalk, thresh the plant residue, and separate the beans from the pod. After harvesting the beans, farmers either transport their crops to a commercial grain elevator or store the beans in their own grain bins to sell later.  After the soybeans are sold, they are transported to processing plants or sold to other countries.

Soybeans are used to make many products that we eat or use every day.  Some of these products include feed for animals, food products, biodiesel, vegetable oils, cleaning products, and crayons.

Interest Approach or Motivator

Ask the students the following questions:

  • Do you know any farmers? 
  • What crops do they grow? 
  • What tasks do they do in spring, summer, and fall to care for the crops? 


Activity 1: Key Details
  1. Read My Family’s Soybean Farm aloud as a class, or in small groups. 
  2. After reading ask, “What was the book about?”
    • Students may say soybeans or Alexander and Isaac’s farm. 
    • Soybeans is the overall topic of the book, but there are many things that happened during the story.
      1. Next, ask them for more specific things that happened during the story and what time of year these things took place? Develop a list on the board.  As a class, identify 2-4 main events that took place in each season.   
      2. Distribute the What Happened Worksheet or ask them to write “Spring, Summer, and Fall” on three pages in a science Journal or notebook. 
      3. Give them a few minutes to think about and list details that they remember about each event on the worksheet.  Ask students big-picture questions, like those below, to help recall details. 
        • How did the soybean plants change in each season?
        • What did the Alexander, Isaac, and their dad do?
        • What happened to the soybeans after harvest?  
      4. Display the Vocabulary List , and ask the students to try to add those words in their description of the events. 
      5. Next, use the Seasons Pictures PDF to display pictures from the book that portray each season. Showing one season at a time, ask the students to use the pictures to help recall more detail about the events in the story.  
        • The pictures are from the pages below of the book:
          • Spring: pages 6-9
          • Summer: pages 10-13
          • Fall: pages 14-20
      6. Display the Vocabulary Definitions to help the students expand and refine their descriptions.
Activity 2:   Creative Writing  
  1. Ask the students to re-write the story from the perspective of a soybean. 
    • Encourage them to use their notes from Activity 1, and include all of the vocabulary words in their story.  You may display or distribute the vocabulary sheet, or have students refer to the book’s glossary.
    • Ask them to include language that pertains to time, sequence and cause/effect (first, before, next, then, and last, etc.). 

Essential Files (maps, charts, pictures, or documents)

Did you know? (Ag facts)

  • Iowa is the top soybean producing state in the U.S.
  • Soybeans are used in many common household items, including plastic, crayons, inks, and more.
  • Soybeans are used to make a protein-rich feed for livestock, such as pigs, turkeys, and chickens.
  • Most school buses in Iowa run on biodiesel, a renewable fuel made from soybeans. 

Extension Activities

  • Ask students to read their creative writing pieces aloud to the class.
  • Post the creative writing pieces around the room and do a ‘gallery walk’ and ask each student to read at least three other stories.
  • Ask students to take their writing pieces home and read them to a parent or family member. Have the students interview their family member about the way that soybeans are grown and harvested.
  • Ask students to draw a picture of their soybean what happens during one season of the year. The picture should reflect their creative writing piece.
  • Plant and grow soybeans as a class.
