Learning Guide

Step-by-step guidance. No preparation required.

  1. 1

    Introduction5 Min

    • Ask the big question: "Why did the Wampanoag plant corn, beans and squash together in the same small hill?"
    • Move on when Child offers an initial theory or hypothesis about why the three plants might be grown together.
  2. 2

    Explore & Plan8 Min

    • Place the three types of 'seeds' on the table for observation.
    • Discuss what each plant needs: "What does a tall corn stalk need to grow upright?"
    • Ask for predictions: "If you plant them all together, what do you predict will happen?"
    • Move on when Child describes basic needs for each plant type and makes a prediction about their interaction when planted together.
  3. 3

    Discussion6 Min

    • Explain symbiosis: "Symbiosis means living together for mutual benefit, like a team!"
    • Describe each plant's role: "The corn is a pole, the beans feed the soil, and the squash keeps weeds away."
    • Ask for deeper understanding: "Can you think of other ways nature shows teamwork?"
    • Move on when Child can explain the role of each 'sister' plant and understand the concept of symbiosis.
