    What?!!!

    A fish can live without water…!!!

    Yes, kids. This how wonderful our earth is.

    Let me introduce you to Mr. Lungfish.

    A South American Lungfisg. Found this from http://www.ucmp.berkeley.edu/vertebrates/sarco/dipnoi.html

    A South American Lungfisg. Found this from http://www.ucmp.berkeley.edu/vertebrates/sarco/dipnoi.html

    Today, we can fonly find lungfish in Africa, South America and Australia.

    So, what make this fish so special that is can survive without water.Some lungfish can survive in dried up rivers for weeks or months.

    Well, in waters lungfish use their gill to respirate or breathe. If the rivers dried up, the air will go throughh a lunglike organ called a swim bladder. This is because the swim bladder consist a lot of tiny blood capilary or in general terms blood vessels which act as lungs. (As we all know, 😉 exchanges of oxygen and carbon dioxide happen in our lungs). Thus gas exchanges happen in this swim bladder thingy and our lungfish friend can keep pon surving without waters.

    Kids, do you know that the skin is the biggest organ in our body? And, do you also know that our skin cells can live for three weeks.

    Today, we gonna have some fun with our skin.

    The materials required are:-

    1. Our body 😉
    2. Paper clips, you need at least two.
    Hi Kids...

    Hi Kids...

    Steps:-

    1.Shape you paper clip like this (One Paper Clip)
    By now you should know what do I meant by One Paper Clip...

    By now you should know what do I meant by One Paper Clip...

    and like this (Two Paper Clip)
    Is just two pointed metal

    Is just two pointed metal

    2. Ask a friend to close his eyes. Prick the palm of his hand with one paper clip. Prick his palm again, this time with two paper clips. Record the results (whether the stimulus was felt or not) in table below
    3. Repeat step 2 to test the skin in different partsof the body such as fingertips, arms, neck and knee.

    You should get the results something like this:-
    (√) shows that the skin can detect the stimulus

    (X) shows that the skin cannot detect the stimulus

    Parts of the body Prick with one paper clip Prick with two paper clip
    Palm X
    Fingertip
    Neck
    Knee X X X
    Arm X X X

    Explanations:-
    After this experiments, you will find out that different part of out body have different sensitivity and the skin around the neck and the fingertips is more sensitive than the skin on the palm, knee and arms. This is because sensitivity of our skin depands on:-
    a) the thickness of our skin
    b) the number of sensory receptors (will be wirtting a more simple version on this soon…for please refer to Wikipedia for now)

    Children come from fusion of (or make simple meet up with) mama’s ovum and dad’s sperm known as zygote. So, how does ovum and sperm meet in the first place?

    Race of the Sperms

    Through sexual intercourse, sperms in dad’s reprodcutive organ will flow into mama’s reproductive organ (into the Ovari, which release a ovum). There will 200 – 300 million sperms rushing to the ovum, only one race winner will meet up with ovum to form zygote.

    Sperms Rushing Towards Ovum

    Sperms Rushing Towards Ovum

    Only one sperm can go into ovum to complete the fusion.
    There is only one winner

    There can only one winner

    To become a embryo, zygote divide into two, then two become four,and it keeps repeatedly divide, and being push to the uterus at the same time.
    Zygote Starts To Dividing

    Zygote Starts To Dividing

    Until the eighth day, the dividing zygote implants itself on the wall of the uterus and make a home there.
    Zygote sticks itself onto uterus wall

    Zygote sticks itself onto uterus wall

    Next, zygote become an embryo. Withins 3 weeks, embryo can grow up to 2mm long
    Zygote Turns Into Embryo

    Zygote Turns Into Embryo

    Four weeks later, embryo becomes 1 cm long, and bones and brain is developed.
    Next, embryo starts to grow bones and brain

    Next, embryo starts to grow bones and brain

    Eight weeks later, embryo grows up to 4cm long, it starts to grow limbs and organs….becoming a feotus.
    Embryo grows limbs and organs

    Embryo grows limbs and organs

    3 months later, feotus starts to grow hair.
    Hair starts to grow on foetus

    Hair starts to grow on foetus

    Come the fourth month, we will know is it a boy or a girl?
    Time to know...Boy or Girl?

    Time to know...Boy or Girl?

    Starting from the fourth month, mama will feel the moving feotus in her stomach
    Mama can feel her baby moving

    Mama can feel her baby moving

    Seventh month, feotus will turn in the uterus and it will keep the up side down position until it is borned… the feotus’s body is filling up the whole uterus.
    Almost time to come out!

    Almost time to come out!

    By the tenth month, mama will giving birth to a new born baby!
    A baby is born!

    A baby is born!
