CONCEPT: Plants reproduce and grow in various ways.
CONTENT OBJECTIVE: 3F2.00 To understand the functions of the parts of a flowering plant
INSTRUCTIONAL OBJECTIVES: The learner will:
2.01 label the parts of flowering plants.
2.02 describe the functions of each part of a flowering plant.
OUTLINE OF CONTENT:
I. Parts of a flowering plant
II. Functions of parts of a flowering plant
TN COMPONENT OF SCIENCE: Unifying Concepts of Science
To enable students to acquire scientific knowledge by applying concepts, theories, principles and laws from life/environmental, physical, and earth/space science.
2.3 ORGANIZATION - Everything is organized as related
systems within systems.
TN STANDARD(S): The learner will understand that:
2.3a Natural phenomena display a wide variety of similarities and differences.
BENCHMARK: There are variations among individuals within all systems.
BENCHMARK: Things can be sorted into groups according to their similarities and differences.
2.3b Groupings are based on similarities related to structure and function.
BENCHMARK: Organisms are separated into groups according to identifying characteristics.
BENCHMARK: Some individuals operate independently of the system, while others operate as a collective group.

This classroom connector addresses Instructional Objective 2.01.
Today, boys and girls, we are going to study the parts of a flowering plant. Let's name some plants with flowers. (responses written on board) What is your favorite? (response) Picture your favorite flowering plant. (pause) Tell me your favorite flowering plant. (The teacher will create a table as favorite plants are listed. The most popular flowering plant will be announced.)
(Hold up a real flowering plant or a picture of a flowering plant. Point to the flower, then each part in turn.) This is a flower. This is a stem. This is a leaf. This is a root.
MONITOR AND ADJUST:
Name each part as I point to it. (Show an orange) What part of a plant is this? (Fruit) Where would we be able to find seeds? (In the orange) (Cut the orange open)
Let students eat an orange slice and try to find the seeds. Name other examples of seeds and fruits.
Think with me one more time. What are the six parts of a flowering plant? (pause) Turn to your neighbor. Name the parts for each other. Now sketch a flowering plant and label the parts.
This classroom connector addresses Instructional Objective 2.02.
Class, let's think about the six parts of a flowering plant. Let's name them again. (root, stem, leaves, flower, fruit, and seed) Today we will learn what job each part does for the plant? (pause) Let's think together about that now.
(Point to each part on a diagram as discussed.) Let's think about the root. It holds the plant in place and gets water and minerals from the soil for the plant to use. The stem is the plant's highway where water and minerals move. The stem also holds the plant upright. The leaves are the plant's food factory. It is in the leaves that food for the plant is made. The flower is special, because that is where the seed begins to grow. The flower can be very pretty to look at. The flower changes and develops the fruit. The fruit grows around and protects the seeds. A new plant comes from the seed. (Show an apple or orange tree close-up picture of a blossom and its changes as it begins to develop into fruit.)
MONITOR AND ADJUST:
(Make a set of index cards for each student using the words: root, stem, leaves, flower, fruit, and seed. Teacher reads the definition of the function of each part of the flowering plant. Students hold up the corresponding card.
1. A root - holds the plant, gets water from soil
2. A stem - water highway
3. The leaves - food factory
4. The flower - blossom, and seed producer
5. The fruit - seed protector
6. The seed - makes new plant
(Have partners count the seeds in an apple, and eat the apple. Compare the results.) Each group of two will record the number of seeds. An average will be found by the teacher.
(1. If in the Autumn, predict the number of seeds in a pumpkin. Count, toast, and eat.
2. Each child should choose a flowering plant and do a one page report. (Allow one week for this.) The report will be presented to the class.
Tell your neighbor what a root does, (pause) a stem, (pause) a leaf, (pause) a flower (pause) a seed, (pause) a fruit. (pause)
