Corn: Structurally Speaking

Entire lesson below.  Also available is the printable PDF version.

This unit, which focuses on plant structures and functions, is spread over several weeks in order to grow corn plants in the classroom to be used in the last lesson.  In the first lesson, students plant corn seeds in order to sprout plants to be used three weeks later.  They also set up their science notebooks to record ongoing observations.  In the second lesson, which involves observations over 3-5 days, students investigate how a seed germinates, with structures and functions of seeds being emphasized.  The third lesson culminates in students observing and drawing a full corn plant, identifying structures and functions of the plant.  These lessons can be modified so that instead of growing the plants in the classroom, full corn stalks are brought into the classroom for the final lesson.
