Students observe each stage in the life cycle of
a simple plant. Working with Wisconsin Fast Plants® (Brassica rapa),
which germinate, mature, and go to seed within a 40-day period, students plant
seeds and watch the seedlings emerge. Later, they thin and transplant seedlings.
As they watch their plants grow, students learn that plants need nutrients from
the soil, as well as water and light, to thrive. As the unit expands to focus on
the interdependence of living things, students cross-pollinate the flowers with
dried honeybees. Finally, they harvest mature seeds and determine seed yields.
These experiences deepen students’ understanding of the characteristics of
living organisms and their relationship with and dependence on their
environment.
