Description of Unit

In this project, grade 2 students will research fruits and vegetables that grow well in their region and area. Students will determine which plants would grow well together based on their needs (e.g., sunlight, water, space). Students will then map out a space for this garden using perimeter and area, design a yearlong planting/harvesting calendar, and create a budget for the materials they would need.

This guide links the How Does Your Garden Grow? unit to the Texas Essential Knowledge and Skills (TEKS) for second graders. How Does Your Garden Grow? is a science unit that allows students to study how plants grow and plan a garden. How Does Your Garden Grow? also has interdisciplinary connections to English language arts, mathematics, and social studies disciplines. For example, students will follow a research plan for gathering relevant information, as outlined in the English Language Arts and Reading TEKS; and students will identify ways humans are both producers and consumers, as described in the Social Studies TEKS. The following document includes the applicable TEKS and the details of the How Does Your Garden Grow? unit. The final section of this document presents the applicable Texas College and Career Readiness Standards adopted by the Texas Higher Education Coordinating Board (THECB) on January 24, 2008.

Phase I. Learning Experiences

  1. Read a book about garden vegetables to the class. Examples include The Vegetables We Eat by Gail Gibbons or Planting a Rainbow by Lois Ehlert. Discuss plant needs with students by posing questions:
    • What do plants need to survive?
    • What are the parts of a plant that help it get what it needs?
    • Do all plants grow in all places? Why or why not?
  2. Organize students into groups of four and lead them on a weed walk. Try to find a weed that can be pulled up by the root for each group, and let the students take these weeds back to class. Students will record their observations/illustrations in a journal. Students will draw and label the plant with the correct terms and functions. Explain what a root is and what its function is for the plant. Then have the students dissect the root from the weed. Explain what a leaf is to the students and its function for the plant. Have the students dissect the leaf from the plant. Repeat these steps for the flower (if there is one) and the stem.
  3. Bring in (or have students bring in) examples of fruits and vegetables (e.g., carrot, spinach, potato, onion, lettuce, pumpkin, celery, apple, orange, strawberry). Discuss the different parts of the plant with students. Give each group of students a fruit or vegetable and have them determine if they would be eating the root, stem, leaves, or flower of the plant when eating this item. Students will brainstorm a list of how they could find out more information on the fruit or vegetable they are examining. Discuss the use of the Internet, library books, and other resources. Provide access to websites and resources to allow student to find interesting facts about their fruit or vegetable. Have student illustrate their fruit or vegetable and share what they have learned with their classmates in a one- or two-minute presentation. Students will document their sources.
  4. Invite guest speakers from local plant nurseries or landscaping businesses to speak to students about what types of plants grow well in their area, how to care for plants, and how to start a garden. Speakers may also discuss the importance of these plants in the world. Students will take notes on what they learned from the guest speaker. Students will record new vocabulary or language that this professional used in their presentation.
  5. Students will look at pictures of different gardens. Gardens come in many shapes and sizes, such as triangles, squares, rectangles, or circles. Have students practice creating these shapes on graph paper and measuring the perimeter of these gardens.

Phase II. Independent Research

A. Research process

  1. Selecting a topic. Students will work individually or in a small group to research what types of fruits, vegetables, or flowers grow well in their area. They may use Internet resources or advice from guest speakers to make their choices.
  2. Asking guiding questions. Once students have selected between three and five plants, they will come up with three guiding questions that they will research for each plant. Examples include the following:
    • What does this plant need to survive (e.g., soil, space, fertilizer)?
    • What type of environment would you need to plant it in (e.g., sunny, shady)?
    • When is the best time to plant seeds and harvest this plant?
    • How does this plant change over time?
    • What similar patterns in growth and development do you see in the different plants?
    • How could changes in the weather affect the plant growth?
  3. Creating a research proposal. Students will describe how they will find the answers to their guiding questions and how they will record their notes and information. See the attached research notes page that can be used as a guide.
  4. Conducting the research. Students will use Internet resources, books, and other sources to gather information about their chosen plants and how these plants will best grow. Students will take notes on their findings in order to complete the project.
  5. Sharing findings. As part of their research, students will create a map of their garden. The map will include how big the garden would be, how many of each type of plant would be in the space, and where they would be located. The students will also show a monthly schedule of when they would plant each plant and when the plant would be ready to harvest.
  6. B. The product

    Each student will write a report or description explaining which plants they chose and what the plants need to survive. The report will include a map of their proposed garden and a planting schedule. Students will document which resources they used for the report. If physical resources are available, students can actually plant their garden in the school area and use pictures and products of the garden in their report/presentation.

    C. Communication

    Each student will present to the class and invited guests (possibly including local gardeners, nursery owners, etc.) what he or she has learned. The presentation will include the completed report, a planting schedule, and a map of the garden. The audience should be given time for questions and answers. The Q&A session should be unscripted in order to reflect student learning accurately.

    D. A completed project consists of

    1. the research proposal,
    2. research notes in a chart format,
    3. a written report,
    4. a monthly schedule of planting and harvesting,
    5. a map of the garden, and
    6. a presentation to the class and invited guests.
