Objective(s):

This lesson is designed for freshman level biology, but it is easily adaptable for lower grades.

Students will be able to identify the parts of a flower.

Students will be able to distinguish between a perfect and imperfect flower.

Students will improve coordination and dexterity.

Materials:

Flowers (preferably ones with both male and female sex organs)

Tweezers

Paper

Scotch tape

Scalpel if desired

Strategy:

This may be used as a culminating activity or as an introductory activity. Have students obtain a flower, tweezers, tape and scalpel if desired. Students will remove the parts of the flower (petal, sepal, stamen, pistil or carpel) and tape the parts to a sheet of paper. Students will then label each part and the parts of the stamen and the pistil or carpel.

Performance Assessment:

Students will turn in the paper they just finished taping and labeling. This assignment can be an easy and fast assessment.

Conclusions:

Students should, when complete, be able to identify the parts of a flower and tell whether or not the flower has both male and female sex organs (perfect) or just one sex organ (imperfect).

Any freshman biology text will aid in identification of parts.
