1 Lesson Plan – Biology 10 th Class Topic- Control & Co-Ordination Sub Topic-Nervous System In Humans
2 General Objectives To develop scientific attitude among students. To inculcate leadership quality.To inculcate spirit of inquiring.To develop habit of working in group.To co-relate knowledge with the environment.
3 Specific ObjectivesTo impart knowledge about control & coordination in human beingsStructures & function of Nerve cells.Importance of synapses.

5 P K TESTING What happen when you step on banana (kele ka chhilka)? Teacher will ask to hold tightly wrist of another student and ask question?Why you pull of your leg when a thorn prick you?Why your mouth watered when you see or think of about delicious food?Why do you plug your ears during loud sound of fire crackers?
6 What is this ?What is the function of this Organ?
7 Name the AnimalWhat is he doing?Which Organ is responsible for this ?
8 What is cow doing?What is the function of this organ?
9 What is happening in this picture? Which organ is responsible for this event ?
12 There are two Major Systems in The Body Which controls & coordinates the body activities Such as: Digestion Respiration, Excretion, Movements etc. along with all these five sense Organs.
13 In animals Nervous system & Hormonal system plays an important role in control & co-ordination. TEACHER SHOULD ASK QUESTION TO STUDENTS ABOUT TWO SYSTEM OF CONTROL AND COORDINATION
14 HUMAN NERVOUS SYSTEM WHAT DO YOU SEE IN THE PICTURE? POINT OUT TWO PARTS OF HUMAN NERVOUS SYSTEMWHAT ARE THE FUNCTIONS OF NERVOUS SYSTEM?
15 Nervous systemreceives and responds to information about what happens inside and outside of bodyStimulus - any change that brings about a response (reaction)maintains homeostasis
16 Central nervous system (CNS) - made up of brain and spinal cord The brain is the control center of the body
17 Spinal cord - links brain with peripheral nervous system Spinal cord - links brain with peripheral nervous system. Controls reflexes. Protected by vertebrae.
18 Peripheral nervous system (PNS) – nerves branch from CNS (brain/spinal cord) to body Somatic N.S: voluntary actions- Autonomic N.S: involuntary actions (reflexes)
19 Both the part of nervous system (CNS & PNS) formed of some specific cell. Can you tell me the name of those cells?
20 NEURONSTRUCTURAL AND FUNCTIONAL UNIT OF NERVOUS SYSTEM
21 Neuron – cell that carries information (nerve impulse) through the body Has three parts: 1 .Cell body – contains nucleus 2 . Dendrite – carries impulse toward cell body 3 . Axon – carries impulse away from cell bodyStudents should be asked to draw structure and mention its parts
22 Three types of neurons: -Sensory neuron – receives information from senses -Interneuron – carries impulse from sensory neuron to motor neuron -Motor neuron – sends impulse to muscle for actionStudents should be asked to draw structure and mention its partsWhat are the function of each part?
23 There are millions of neurons in human nervous system These neurons are connected to each otherNote:- Ask about the connection between the two neurons i.e. Synapse.
24 Synapse-The junction between two neurons or with muscles is called synapse.
25 STRUCTURE OF SYNAPSE Synapse have three parts 1 Axon terminal 2 Gape junction3 Dendrite of another neuronSynapse transfer information from one neuron to another through chemicals.
26 PATHWAY OF NERVE IMPULSE Draw the flow chart and find the pathway of flow of nerve impulses.
27 Identify the parts of nervous system and labble them.
28 Name the two system of control and coordination.
29 MATCH THE COLUMN A B 1 organ of sight 2 Nerve cell 3 Controlling Centre4 Synapse5 Sensory Neuron1 Neuron2 Junction between neurons3 carry information to Brain4 Eye5 Brain
31 Group FormationAccording to the strength of class (usually 5-6 students in a group)
32 Group Activities GROUP -1 Prepare a list of example of control and coordination in animals.GROUP-2Prepare a chart showing structure of Neuron.GROUP-3Draw a flow chart of information between environment and nervous system.GROUP-4List the sense organs and find out their functions.
33 Presentation Of Group Based Activities Students will present their activities
34 Assignment /Feedback Organ of hearing……………………………………………………………. Basic structural and Functional unit of nervous system is………………………………… receives information from surroundingsWhich part of neuron receives informationName the site where conversion of electric signal to chemical signal occurs in a neuronName the sense organ found in your body.Why do we constrict our eyes during bright light?Director of Body is (a) Heart (b) Kidney (c) Brain (d) Lungs.The connection between two neuron is called (a) dendrites (b) synapse (c) Axon (d) impulseSensory neuron carries information from Sense organ. (Yes / No).Name two types of system which is responsible for control & coordination.
35 HOME ASSIGNMENT Write down the function of nervous system. Prepare model of a Neuron.What is a Synapse? Discuss its functions.Differentiate sensory and motor neuron.
