Plants: Supplemental Guide 3A | The Life Cycle of a Plant 79Introducing “The Life Cycle of a Plant”
- Tell students that in today’s lesson, they will learn about the life cycle
of a plant. - Explain that when something happens in a cycle, it happens over and
over again.
Making Connections - Ask students to think about what they do every day. Have them
consider what they do in the morning, afternoon, evening, and
nighttime. - A sample student’s daily cycle may be to wake up, eat breakfast, go
to school, come home, eat dinner, take a bath, and sleep. - To make the concept of cycle more concrete, have different students
stand in a line and act out each part of the daily cycle. After they
sleep, they wake up in the morning and start the cycle again. Have
the last student in the cycle loop back to the first student, forming a
circle. Have students repeat the cycle with you. Be sure to emphasize
that a cycle is something that happens over and over again.
