Life science students learn about flowers
Students make models, dissect fruit. . .

The Life science class has been busying study plants; as part of their studies, they have been learning about angiosperms (flowering plants). To help them better understand the flower parts and processes, student groups created a 3-D model of a flower. They had to have the four main parts of a flower (sepals, petals, stamen, pistil) as well as being able to describe the processes their plant used for pollination, fertilization, fruit production, and seed dispersal. Each group then presented to the other groups on their processes.
On another day, students entered the classroom to find “secret containers” on their desks. After much anticipation, they discovered that each container held a different fruit. They observed the outsides of the fruit, observing the nature of the fruit (dry, fleshy) and looking for marks such as the flower scar. They then predicted how many ovules (eggs) each flower their plant had initially had. They then all cut into their fruits and observed the seeds. Their ovule predictions were pretty close, as the fertilized eggs turn into seeds.
After they all observed everyone’s fruits, they then tasted the ovary walls. In eating the fruit, they also aided the plants with seed dispersal. And, if you get that last joke, you really know your angiosperms!
