A Field of Sun (p. 180)


Step 1. Questions

Sunflowers react to their environment. They face east to protect themselves from the Sun. When they grow, they follow the Sun as it moves across the sky. Did you know that other plants react to their environments, too? Daisies close their petals at night. Cactus plants fill themselves with water when it rains and then save the water to use during many hot, dry days.

Choose a plant and write a description about how that plant reacts to its environment. Begin by researching plants and their environments. Here are some questions to guide your research:
  • How do different plants react to the Sun?
  • What plants react to the seasons and the weather?
  • Do plants react to insects or animals?
Are you ready? Begin by visiting the Web sites listed in Step 2. Look for answers to the questions above, and write down what you learn in the note-taking boxes.

With teacher supervision, you may use search engines to research other Web sites. You also can research plants and their environments at the library. When you are ready, follow Steps 3 and 4 to write your description.



Step 2. Research

Research answers for the questions you were asked in Step 1. Visit these Web sites. Take notes about them on this page, too!
