The document describes developing a digital lesson plan on excretion in humans using ICT tools like PowerPoint. It discusses how visual media like videos and images help students learn and remember topics better compared to just audio. The lesson plan covers the structure and working of the kidney, nephron, and formation of urine. Interactive tools like questions, diagrams, and multimedia are used to enhance understanding and engagement. The goal is to pique students' interest in biology topics and help them learn scientifically using innovative digital methods.

2.  Visual perceptions remains in the brain for longer time
then what we hear.
 With pictures and videos we can understand in a better
way.
 Videos shown are printed in our mind . we can have
visual perspective and can remember longer.
 We can see the points that we miss while hearing.
 Playing animation and sound effects adds little more to
effective teaching.
 Since it is interesting, we will not fall a sleep.

5.  To develop the interest and curiosity among pupil about
“Biology’’ through ppt - ICT tool.
 To think and learn scientifically the terms, concepts,
principles, laws and theories of “Biology” using
Multimedia approach.
 To develop awareness and critical thinking among the
pupil towards the subject “Biology” through innovative
digital lesson.
 To develop reasoning power in “Biology” through
creative preparation of slides.

6. KNOWIEDGE:

Q1) Name some of the important system of human being ?
ANS: Digestive system, repiratory system, reproductive system.
Q2) Which organ helps in digestion ?
ANS: Stomach helps in digestion.
Q3) Which organ helps in respiration ?
ANS: Lungs helps in respiration.
Q4) Which internal organ helps in excretion ?
ANS: Kidney helps in excretion.
Q5) Removal of waist products is called as ?
ANS: Excretion.
STATEMENT OF AIM.
Let us study aboutLet us study about “Excretion In Human”.“Excretion In Human”.

11.  Like otheranimals humans have
a systemthat excretes Nitrogen
wastes as Urea, Salts and Water.
EXCRETION:-
 The removal of Nitrogeneous
waste from the body is called
Excretion..

12. Excretory systemconsist ofExcretory systemconsist of
1.A Pairof kidney.
2.A Pairof Ureter.
3.Urinary Bladder.
4.Urethra.

13. Kidney are been shaped struture about
10cmlong. They are located just above
the waist on eitherside of the backbone.
The right kidney is placed slightly above
the left.
A Narrow tube called the Ureterruns from
the innerside of each kidney. The Ureter
inturns are connected to a large sac like
structure called Urinary bladder.
Leading from Urinary bladderis
anothermusculartube called Urethra.
STRUCTURE OF KIDNEYSTRUCTURE OF KIDNEY

14. A longitudinal section of a kidney reveal an
outercortex and innermedulla. The
medulla consist of 8-18 pyramids like
structures.
At the end of pyramid there are minutes
opening called renal papillae. Pyramids
project into the innerhallow peluis,
Ureterstarts fromthe peluis.
Each kidney consists of about one million
Nephrons, Blood cappillaries and
connective Tissue.

17. Student teacher will ask the below question.Student teacher will ask the below question.
Q1)) Define excretion ?
ANS: The removal of nitrogeneous waste fromthe body is
called excretion.
Q2) Explain the shape and size of kidney ?
ANS: Kidneys are bean shaped structure darkreddish
brown in colour, about 10 cm long.
Q3) How many nephrons are present in each kidney ?
ANS: Each kidney consist of about one million nephron.

Black Board Summary.
The nitrogeneous waste of human are urea, salt and water. The
excretory system consist of a pair of kidney, a pair of urater,
urinary bladdder, urethra.kidney is located just above the
waist on either side of the back bone.kidney consist of about
one million nephron, blood capillaries and connective tissue.
Urine is formed by three steps,glomerular filtration,
tubular/selective reabsorbtion, tubular secrition.
