5E Inquiry Lesson Plan
Title: Fruit and Flower Dissection Lab with Microscopic Observation of the Lily Anther
And Ovulary
Grade level: 7th
National Standards:
National Science Education Standards for Life Science Content,
Standard C, grades 5 – 8 (structure and function in living systems, reproduction and
heredity).
ACOS:
SC 2005:
1. Describe characteristics common to living things, including growth and development,
reproduction, cellular organization, use of energy, exchange of gases, and response to
the environment.
2. Relate major tissues and organs of the skeletal, circulatory, reproductive, muscular,
respiratory, nervous, and digestive systems to their functions
3.Identify major differences between plants and animals, including internal structures,
external structures, methods of locomotion, methods of reproduction, and stages of
development.
Objectives:
1. Identify the sexual organs of angiosperms (flowering plants) including both male and
female reproductive structures.
2. Describe the functions of the major sexual organs of a flower.
3. Explain how a fertilized seed is formed within a flower from an egg combining with
pollen.
4. Distinguish between monocot and dicot plants.
5. Identify the various parts of a fruit.
6. Explain how a fruit is formed.
7. Explain why some flowers produce fruits.
8. Examine meiosis in the male and female reproductive structures of the lily by
examining microscope slides of the lily anther and the lily ovulary.
Procedures
Materials:
1. Flower Dissection: Groups of Four
