Facts  The main food of hydra comprises small insects, larva.
 Hydra is found in water.
 Hydra is carnivorous.
 Hydra captured food through tentacles.
 The prey caught by the tentacle, is taken into the body
through the mouth.
 Digestion was completed in food vacuole.
 Hydra has partially intracellular and extracellular digestion.
 Tapeworm is seen in the small intestine of man.
 Tapeworm does not have a complete alimentary canal.
 Enzymatic chemical process of digestion is not found in the
tapeworm.
Concept Hydra and tapeworm both are fresh water living organism.

2. Learning
outcomes in
terms of
specification.
Enables the pupils to acquire following ideas:-
 Factual knowledge about the nutrition’s in other organisms.
1. Recalling new terms like larva, carnivorous, tentacle,
mucus etc.
2. Recognizing the peculiarities of digestion in tapeworm.
 Conceptual knowledge about nutrition’s in hydra and
tapeworm.

2. Explaining the mechanism of feeding of tapeworm.
 Procedural knowledge about the nutrition’s in hydra.
1. Implementing practical knowledge about the process of
digestion in hydra and tapeworm.
 Meta cognition knowledge about the nutrition in hydra and
tapeworm.
1. Differentiating the functions of interior part of small
intestine.
 Scientific attitude towards organisms and their digestion.
1. Showing interest to know more about the process of
digestion in hydra.
 Process skills like,
1. Explaining the importance of villi in small intestine.
2. Explaining the importance of digestive process in hydra.

Video clipping showing hydra.
A flow chart showing the importances of tap worm.

3. Class room interaction procedure Expected pupil response
INTRODUCTION
1. What do you have eaten today?
2. Do human beings only need food?
3. Do all animals need food?
We know that animals are of
different level.
4. Do name some animals with small size?
PRESENTATION
Activity-I
Teacher divides the pupils into group
and shows the video clipping of hydra
and told them to write the answers of
given indication.
1. Puttu, dosha
2. No, animals also need food.
3. Yes
4. Cat, dog, amoeba, hydra,
tapeworm.
Tentacle

4. Indicators
1. Name the organism you seen in the
chart?
2. Name the part in which the capture its
food?
3. Is hydra is carnivorous?
Group discussion lead by the
teacher
Hydra is an organism found in water and
the hydra is carnivorous. Hydra captured
its food using tentacles. The prey caught
by the tentacle is taken into the body
through the mouth.
Activity-II
Teacher divides the pupils into groups and
gives the flash card and told them to write
the answers of given indicators.
Hydra
Tentacle
Yes, hydra is carnivorous.

5. Tapeworm
The tapeworm is an endoparasite seen
in the small intestine of man. Tapeworm
does not have a complete alimentary
canal. It absorbs simple nutrients from
the small intestine of man directly
through body surface the enzymatic
process of digestion is not found in the
tapeworm.
Indicator
1. Where the tapeworm is found?
2. How the tapeworm absorbs the
nutrients from the small intestine?
3. Is tapeworm having alimentary canal?
Group discussion lead by the
teacher
Tapeworm is an endoparasite seen in
the small intestine in man. It does not
have an alimentary canal. It absorbs
nutrients from the small intestine of the
man directly through body surface. The
enzymatic chemical process of digestion is
not found in the tapeworm.
In the small intestine of man
Through body surface
No

6. Review
1. What is meant by endoparasite?
2. How digestion is takes place in hydra?
3. Where does the digestion completed?
4. Where the tapeworm is found?
Follow up activity
Draw the picture of hydra and describe the process of digestion?
