Lesson Plan of Parts of Plant

General Science

Grade IV

Students` Learning Outcomes

Demonstrate the plant
Differentiate between parts of the plant.
Define the roots, flower, stem, leaves, fruit and seeds.

Information for Teachers

Teacher knows that:

Parts of plants: A plant has roots, stem, leaves, flowers, fruits and seeds.
System of parts of the plant: These parts of the plants form two systems which work together. These systems are root systems and shoot systems.
Root systems: Root systems consist of stem and its branches, leavers, flowers, fruits and seeds.
Functions of roots:

1. Root fixes the plant firmly in the soil.
2. Roots absorb water and dissolved salts from soil.

Importance of roots in our daily life

We use many roots as food for example radish, carrot, turnip etc.

Types of Stem:

1. 1. Woody stem
  2. Soft stem
  3. Weak stem
  4. Underground stem

Functions of stem:

1. 1. Stem provides support to the plant.
  2. A stem conducts water and minerals from roots to leaves.
  3. Some stems for example sugar-cane, potato and ginger store food in the.

Importance of stem in daily life:

We use woods as fuel.
Woody stems are excellent for making furniture, doors, windows and many useful things.

Simple and Compound Leaves:

Simple Leaves: Leaf blade of many plants in one piece, such leaves are called simple leaves as people, mango, and banyan`s leaves.
Compound Leaves: Leaves of rose, keekar and amaltas have their leaves blade cut into many small leaves. These leaves are called compound leaves.

Functions of Leaves:

Leaves are mostly green in colour. They contain chlorophyll in them. With the help of chlorophyll, leaves capture light and use it to prepare food by combining water and carbon dioxide. Oxygen is released in this process.

Different parts of a flower:

The floral parts are arranged in four circles. These are:

1. 1. Sepals
  2. Petals
  3. Stamens
  4. Carpals
  5. Sepals: sepals form the outermost circle. They are green in colour.
  6. Petals: The second circle is made up of coloured leaves. They are called petals.
  7. Stamens: Stamens are the male part of the plant.
  8. Carpals: The central part is made up of carpals. They are female’s parts of the flower.

Introduction

Teacher shall ask the students:

Dear students have you visit the garden?
There what you saw? (Expected answer may be as; then students will tell that they saw there different kinds of plants, flowers, leaves, fruits, etc.)
Now teacher will tell the students that today we will read about the parts of the plants, such as roots, stems, flowers, leaves, fruits and seeds.

Development

Activity 1

Select a small plant in school garden and water it.
When the soil becomes soft, pull out plant very carefully so that the plant parts remain in contact.
Now observe the parts of the parts of the plants, root and shoot system of the plants.

Activity 2

Now show the students different roots of the plant.
Mark the Tap root and Fibrous root
Tell the name of roots that we are eaten

Activity 3

Cut a shoot from a flowering plant with white flower.
Place this shoot in a beaker of red coloured water.
Observe the stem, leaves and flowers after a few minutes and inquire from the students such types of question:
Do you notice any change?
Are there any red lines in the stem, leaves and flowers?
What does this tell you?

Activity 4

Show the students different types of stem, for example Grass, Sheesham, keeker, Rose, potato, and ginger.
After that explain the woody stem, weak stems, soft stems and underground stems.

Activity 5

A few leaves for example Mango, Keekar, rose and peepal.
After that explain the simple and compound leaves.

Activity 6

Collect different flowers from home or school and show them to the students their shape, colour, size and its smell.
After that observed the flower to the students and tell them the parts of the flower such as; Sepal, Petals, Stamens and carpals.

Assessment

Teacher asked the students the following questions:

How many parts of the plants?
What is root system?
What is shoot system?
What is function of the root?
What is the importance of roots in our daily life?
How many types of stem?
What is the function of stem?
What is the importance of stem in our daily life?
Describe the simple leaves.
Describe the compound leaves.
What are the functions of leaves?
How many parts of flower?
Describe different parts of flower.

Follow up

Ask the students to write in 4-5 lines about the topics on the writing board.
