    Interactive and Integrative Lesson PlanLife Cycle Reproduction of Animals

    (Date)

    I. Objectives

    Cognitive : Infer that all animals develop from fertilized egg.

    Identify animals hatched from eggs.

    Identify animals born as baby animals.

    Infer that an offspring learns to do what it has to do from its parents.

    Describe how animals grow and develop.

    Psychomotor : Match a baby animal with its parent.Affective : Recognize that some persons are born with special talents, while others have to learn and develop

    them.

    II . Integration

    A. Values: Talents and learning from others.. !a"abayan: Family relationship between parents and children.

    2. Concepts'Related Ideas

    /. ll animals come from a fertilized egg. In some animals, fertilization ta&es place inside the female0s body by amale0s sperm. 1ell!lar reprod!ction ta&es place and an embryo is formed.

    2. In higher animals, the embryo develops inside the mother0s body3 and when it is f!lly developed, it is born liveloo&ing li&e its parents.

    . In some animals, the embryo is formed inside an eggshell that is laid by the mother3 and when it is f!llydeveloped, it is hatched from the eggshell loo&ing li&e its parents.

    '. In other animals, the offspring that hatches from the eggshell does not loo& li&e its parents. 4!t as it grows, itchanges in form and becomes an ad!lt that loo&s li&e them.

    +. (ometimes, fertilization ta&es place o!tside the female0s body. The female lays eggs witho!t shells in the water,

    where the male fertilizes them. The zygote develops into an embryo that develops into an offspring that may ormay not loo& li&e its parents. 4!t even those that are hatched with no resemblance with their parent will changein form, and event!ally loo& li&e them. In other words, all offspring will develop and grow into an ad!lt loo&ingli&e their parents . . . whether they are born live or hatched from an egg.

    5. 6very baby animal will grow to live the way its parent live. It will h!nt food, eat, so!nd, and play li&e no others.6ach baby animal learns from its father and mother many things abo!t being what it sho!ld be in order to stayalive.

    If a chicken comes from an egg where does a cat come from?

    3. Presentation

    !ll organisms whether plants or animals that reproduce by se"ual reproduction come from an egg. #he difference betweena chicken and a cat is that the chicken is laid as an egg while a cat is born li$e.

    In today%s lesson we shall identify animals that are born li$e and animals that are hatched from an egg.

    4. Concept )ormation

    1. &pen your books to page '(.

    2. !ll animals come from a fertili)ed egg. *"plain what fertili)ation is.

    3. In some animals fertili)ation takes place inside the female%s body by a male%s sperm. What takes place after fertili)ation?

    4. What do you call the baby animal before it is born or hatched?

    '. Where does the embryo de$elop and how is it born?+. #hose animals that are born li$e how do they look?

    ,. #o be born li$e means to be born as baby animals looking like their parents. -i$e e"amples of animals that are born li$e.

    . #hose animals that are hatched from an egg do they all look like their parents?

    /. -i$e an e"ample of an animal hatched from an egg looking like its parents.

    1(. -i$e an e"ample of an animal hatched from an egg not looking like its parents.11. 0ut as the offspring grows does it changes in form and become an adult that looks like its parents?

    12. ometimes fertili)ation takes place outside the female%s body. How does this happen?

    13. In all animals the )ygote de$elops into an embryo then into an offspring that may or may not look like its parents. Whether

    they are born li$e or hatched from an egg will the offsprings grow into adults looking like their parents?

    14. In acti$ity 3 on pages '('1 you will identify from the pictures of the animals in ig. 3.2 which are born li$e and which

    are hatched from an egg. #hen in ig. 3.3 you will match the letter of each baby animal with the number of its parent.!llow 2( minutes for the acti$ity.5

    1'. #urn to page '2. How do animals grow? How will it hunt food eat sound mo$e and play? rom whom will it learn to do

    all the things that it has to do in order to stay ali$e?

    1+. Why will a cat ne$er learn to bark?1,. Why will a dog ne$er scratch the ground for food?

    1. Why will a duck ne$er crow in the morning?

    1/. Why will a rooster ne$er learn to sho$el the mud with its beak in search for food?

    2(. In acti$ity 4 you will identify the animals from ig. 3.4 on page '2 which are described by the characteristics stated on

    page '3. !llow 1' minutes for the acti$ity5

    6. ,enerali-ations

    How are animals born?How do baby animals learn to do what they ha$e to do?

    7. Application'Integration

    Some animals are born live, others are hatched from eggs. The same is true with talents. Some men are born with

    outright gifts of talents. But for many, talents are hidden in shells. They have to discover them, nourish them, and make use of

    them.

    We all learn from the examples of others, especially our parents and teachers.

    8. *valuation

    Multiple Choice Test. 6hoose the correct answer.

    1. Most animals reproduce from the union of an egg cell of a female animal with the sperm cell of a male animal of the samekind. his union of the two cells is called

    a5 fertili)ation. c5 o$ulation.

    b5 metamorphosis. d5 incubation.

    2. All living things come from other living things of their own kind. A !a!y animal can only come from a grown"up animallike itself. #or e$ample% a kitten comes from a cat& a puppy comes from a dog& a tadpole comes from a frog& a chick comes

    from a hen& a caterpillar comes from a !utterfly. 'ome animals are !orn live while others are hatched from eggs. hich of

    the following groups of animals are all hatched from eggs

    a5 bird turtle snake dog c5 bee fish li)ard crocodile

    b5 frog chicken bat elephant d5 cow dog alligator monkey
