教學目的 Students will observe interactions between plants and pollinators in nature; students will understand the relationship between flower shape, color and smell to the type of pollinators they attract; students will create a hypothesis and then compare observed results using a graph
教學內容 1. Visit a garden or natural area and identify up to five flowers to observe. Write the name of the flowers on your data sheet. If you do not know the names, you may assign numbers to each plant. 2. Record the characteristics (color, shape, smell) of each flower on the data sheet using words and/or drawings. 3. Using the information from the pollinator syndrome worksheet, make a hypothesis as to which types of pollinators might visit each flower and record on your datasheet. 4. Quietly observe your flowers for 10 minutes each and record the types of visitors to your flowers on the data sheet, using words and/or drawings. 5. Create a bar graph demonstrating your individual observations. You may use color coding to represent different types of visitors. In groups, experiment with different ways to arrange data in graphs using different variables (ie color, shape). 6. As a group, discuss observations, data trends, and reflections. You may use the following questions as a guideline: a. Which of the pollinators were “generalist” pollinators, meaning that they visited multiple flower types? Which of the pollinators were specialized? b. Was every insect that visited your plant a pollinator? What else might insects use plants for? c. Do you think that the time of day could have affected your results? Why or why not? d. How might more plant diversity affect the number of visitors? What are some threats to plant or pollinator diversity?
