1. MOTIVATION:

The teacher gives a brief description about computer and its tasks. Then he focuses on human brain. Then the teacher asks

the following question to arouse motivation among the students.

1. What are the specialties of human brain?

3

2. What are the parts involved in the

3. Among all, which one gives beauty to the plant?

4. How many types of flowers are present based on colour?

5. Have you ever thought of how these flowers are classified?

Then the teacher announces the aim of the lesson and writes title of the lesson on the blackboard as BRAIN.

2. PRESENTATION

CONTENT SPECIFICATION LEARNING EXPERIENCE BLACKBOARD WORK EVALUATION

Parts of a Nervous System

recalls

The teacher asks the students what are the parts of a nervous system. Few students answer the teacher based on what they know. The teacher asks other students to write the answers on the Black board. The teacher collects all the answers and finally consolidates them.

Parts of a Nervous System:

1. Central Nervous System (CNS)

2. Peripheral Nervous System (PNS)

3. Autonomic Nervous System (ANS)

What are the parts of a Nervous System?

CNS, PNS & ANS

distinguishes

The teacher compares the three parts of the nervous system and their components while students are distinguish its components and functions.

Brain

CNS

Spinal Cord

Nerves from brain

PNS

Spinal Cord

Visceral organs

State the parts of the CNS. CNS connected with what? What is PNS? Differentiate CNS & PNS.

Brain locates

The teacher locates the brain which found inside the skull or cranium. Inside the skull the brain is covered by meninges. While all the students are carefully follow the teacher and they locate the brain and its cover.

Skull or Cranium

Cover – Meninges

Which one covers the brain?

5

Weight of Brain

estimates

The teacher enumerates that, the brain weighs around 1300 g or 3 pounds in adults and in new born baby it is around 380 g. The weight of the brain is directly proportional to age. The growth of the brain may happen up to the age of 20. With this idea students estimate the weight of the brain.

Adult - 1300 g / 3 pounds

New born baby – 380 g

Up to age 20

What is the weight of the brain in matured human?

Component of Brain

enumerates

The teacher says that, the basic component of the brain is nerve cells. The nerve cells also called neuron. The brain is made up of nearly 12,000 million neurons. Students enumerate and spell out the neurons.

Nerve Cell – Neuron

12,000 million

Which one is the basic unit of brain?

Parts of the Brain

classifies

The teacher says to the students the brain is classified in to 3 regions namely, Forebrain, Midbrain and Hindbrain followed by the students make them clear.

3 regions

1. Forebrain,

2. Midbrain and

3. Hindbrain

What are the parts of brain?

Cross-Section of the brain

draws

The teacher draws diagram of brain step by step with colour chalk and the students also draw the same gradually in their note book with the help of colour sketch or pencil.

Draw the diagram of brain.

6

The Forebrain elucidates

The teacher makes clear that the forebrain is made up of 3 region, they are cerebrum, two olfactory lobes and diencephalon. Now the students elucidate about the parts of the forebrain.

3 regions

1. cerebrum,

2. two olfactory lobes

3. diencephalon

What are the parts of forebrain?

Cerebrum explains

The teacher explains that, cerebrum is the major part of the forebrain which is divided into two hemispheres. The two hemispheres are connected by a sheet of nerve fibres called corpus collosum at the base. The outer surface of cerebrum is called cerebral cortex. The inner region is called cerebral medulla. The central cortex has sulci and gyri. The students grasp enlighten explanation of the teacher.

Cerebrum:

Two hemispheres

Connection - Corpus collosum

Outer - Cerebral cortex

Inner - Cerebral medulla

Central cortex - Sulci & gyri

Which one connects the two hemispheres?

Cerebral cortex and Cerebral medulla

observe the differences

The teacher shows the model and differentiates cerebral cortex and cerebral medulla based on location, colour, etc. The students observe the differences and follow the same and note it.

Cerebral cortex Cerebral

medulla

Outer surface of cerebrum

Inner region of cerebrum

Grey in colour White in colour

Also called grey matter

Also called white matter

Differentiate Cerebral cortex and Cerebral medulla.

Cerebral Hemispheres

distinguishes

The teacher shows the picture and distinguishes the four different lobes of the cerebral hemispheres. They are frontal, parietal, temporal and occipital lobes. Now the students distinguish the different lobes.

Four lobes: 1. frontal, 2. parietal, 3. temporal and 4. occipital

How many lobes present in cerebral hemispheres? What are they?

Olfactory Lobes

grasps

The teacher shows the model and says that olfactory lobes are two small projections formed from the frontal lobe of the cerebrum and these are not noticeable in man. The students grasp and make a note.

Two small projections

Not noticeable in man

From where are the olfactory lobes formed?

Diencephalon locates

The teacher explains about that, the diencephalon in found deep inside of the cerebrum which consists of two regions namely thalamus and hypothalamus. The student locates the diencephalon in the picture that he draws.

Diencephalon : deep inside of the cerebrum

1. Thalamus

2. Hypothalamus

Where diencephalon is found?

What are the regions of diencephalon?

Infundibulum isolates

The teacher explain that, the hypothalamus bears an infundibulum, having the most important Pituitary gland at its tip and ask the students to isolate the pituitary gland with different colour while all the students isolate the pituitary gland with different colour that he draws.

Infundibulum

Pituitary gland

Where is pituitary gland found?

3. REVIEW / RECAPITULATION

1. List out the parts of the brain.

2. Briefly explain the structure of the brain?

3. Differentiate: cerebral cortex and cerebral medulla.

4. What are the parts of diencephalon?

4. HOME ASSIGNMENT

1. Draw the diagram of a coloured human brain and label it.

2. Collect and preserve the various pictures of human brain.

Signature of the Mentor Signature of the Student Teacher

The Midbrain locates

The teacher explains that, the midbrain is found in the middle of the forebrain and the hindbrain. Students locate the midbrain in the picture.

Forebrain

Midbrain

Hindbrain

Where is midbrain found?

The Hindbrain

realizes the importance

The teacher explains the hindbrain that, this is the posterior part of the brain. This is made up of pons virolii, medulla oblongata and cerebellum. It is an enlarge portion of the spinal cord. The nerves of ANS are associated with this region. The students are carefully followed the teacher and realizes the importance of hindbrain.

Hindbrain - posterior part

Pons virolii

Medulla oblongata

Cerebellum.

Nerves of ANS.

How is the hindbrain made of?
