To illustrate many aspects of amaryllis and paperwhite narcissus growth. To make use of various sources of information (observation, journals, measurements) to create a life sized drawing of the plant at the beginning and end of the unit.

At the end of the unit, students were asked to create a life-sized drawing of the plant as it looked at the beginning of the unit and at the end. They were given measurements and paper strip records of initial and final heights, and they used their own journals to help them remember how the bulb and plant looked initially. Also, they were asked to include many details and features of the plants as they looked at the end of the unit.

In their drawings and paintings that showed the plant at the beginning and end of the life cycle, students generally represented many details of the plants. These included: actual size, features of the plants and flowers, and color. We noticed students measuring across the flowers and counting stamens. Most students represented final height accurately. In some cases, small details were shown, but proportions were not preserved. In general, students made good use of their own journals as a resource for how the plants looked at the beginning of the life cycle .
