Experiment

Shoe Box Potato Maze
This experiment requires a sturdy shoe box with a tight fitting lid.
You will also need a sprouting potato planted in a tea cup. Use toothpicks to hold the potato approximately one centimetre above the bottom of the tea cup and add water.
Try not to spill or splash water in the shoe box since water will eventually cause the cardboard to disintegrate.
Phototropism

Installing the light baffles
Open the box and install three light baffles as shown in the diagram to the left.
It is essential that these baffles be absolutely light-tight along all edges and against the lid when it is fitted. If the baffles are glued in place their edges should be light-sealed with a couple of layers of black duct tape.
Finally, cut a circular hole in the end of the box to admit light into the interior.
Phototropism


Installing the cover
It is important to prevent light from leaking over the top of the baffles where they come in contact with the lid. Two methods have proved useful.
  1. Cut a thin sheet of foam padding to fit exactly inside the lid.
  2. Cut three or four thickness of heavy felt to fit exactly inside the lid.
Carefully install the lid and gently weight it down so that it compresses the padding against the baffles and edges of the box.
Phototropism




Running the experiment
If the box is properly assembled, the only opportunity for light to enter the box is through the hole in the end of the box. Covering the box (leaving the hole exposed) with a black cloth provides additional protection from the effects of unwanted light entering the box.





Phototropism

Observations

This response is known as a phototropic response. The effect is called phototropism .



Phototropism

Explanation

The green leaves of some plants are very sensitive to light. These plants have evolved to spontaneously grow towards a source of light.

The reflection and absorption of sound
1.   When sound waves are blocked by an object, they may be reflected or absorbed by the object.
2.   An object which has hard and smooth surfaces is a good sound reflector.
      Examples : Plank, glass, metal.
3.   Reflected sound is known as an echo(gema). Echo does not occur in a small room because sound is
      reflected very quickly.
4.   An object which has soft and rough surfaces is a good sound absorber. Therefore, soft materias are
      normally used reduce echo especially in a hall. Actions to reduce echo are :
      (a)   The floor of a hall is covered by carpets.
      (b)   Soft cushions and curtains are put in a hall or big room.
      (c)   The walls are lined by sponge or cardboard punched with holes.
5.   Some equipments are invented using the principle of echo to benefit mankind.

     

6.   Echo is used to prevent ships from colliding with rocks under the sea. Echo is also used to trace
      fishes in the ocean and to determine the depth of the ocean.

     

 
Hearing Defect
1.   The most common hearing defects are the inability to detect sound and the difficulty of hearing with
      with ease.
2.   Deafness may be caused by several factors :
      (a)   Damage of the ossicles.
      (b)   Damage of the eardrums.
      (c)   Damage of the cochlea.
      (d)   Damage of the auditory nerve.
3.   Bacterial or viral infections and high fever may lead to damage of the inner ear.
4.   Long exposure to loud sound may increase the chance of becoming deaf.
5.   Some of the hearing limitations can be corrected by using modern devices.
      (a)   Hearing aids can be used to help people with hearing problems.
      (b)   Surgery can be carried out to replace damaged ossicles and to repair damaged eardrums.
      (c)   Implantation of electronic gadgets into the ears can help deaf people to hear again.
6.   Nonetheless, a severe damage of the auditory nerves cannot be corrected.
7.   Looking after the ears :
      (a)   Prevent the ears from being exposed to loud sound, especially while listening to music.
      (b)   Avoid digging the ears with sharp objects.
      (c)   Avoid from inflicting tight slaps onto the ears.
      (d) Clean up the ears with cotton buds regularly so that the ear canal is not blocked.

Stereophonic hearing 

(a)   Hearing by using both sides of the ears is known as stereophonic hearing. 
(b)   Stereophonic hearing allows us to determine the direction of sound accurately.
        i.   A sound coming from the right side will stimulate the right ear first.
       ii.   The sound waves will then, reach the left ear. the impulses are sent to the brain to be
             interpreted earlier than the left ear.
       iii.  The right ear will hear the sound louder than the left ear.
       iv.  The differences in the loudness or speed of the sound that reaches the ears allows us to
             determine the direction or the source of sound.
(c)   The direction of sound is difficult to determine using only one ear.
 

Salam utk semua.!!

Sambil cgu upload gambar..cgu tambahkan sedikit bahan utk bacaan ttg topik yg sedang kita pelajari..jgn lupa ye homework dalam buku SPS page 33-38...standby utk coming exam..!!Another execises will be updated later....

OK..let's begin ..!

SOUND

Sound is a vibration. When something makes a noise it is vibrating, and this causes air molecules around it to vibrate too. These vibrations are transmitted through the air, to our ears, where we perceive them as sound.

You can actually see the effect of sound vibrations with an easy experiment. Get a bowl and cover the top with plastic sandwich wrap. Pull the plastic tight across the top in all directions until it is flat and smooth; tape it tight if necessary. Then sprinkle some salt onto the plastic.
Now get a pot and spoon; hold them near the bowl and hit the bottom of the pot hard with the spoon. You should see the salt jump on the plastic. Try yelling loudly next to the bowl, and you may be able to make the salt jump using the vibrations from your voice.

The loud noise you make is a vibration, which is transmitted through the air, to your ear and also to the plastic. The plastic vibrates, and makes the salt crystals jump! Let's examine how sounds from a vibrating object turn into sound you hear.

So ini cgu berikan notes tambahan utk you all baca.

Eye Problems

Short Sightedness (Myopia) This occurs when light focuses in front of the retina and causes a blur in the distance. It often develops during the early teenage years and is often noticed when the blackboard becomes difficult to read.

 


What happens in short sighted eyes?
Myopia



Long Sightedness (Hypermetropia) This occurs when the eye naturally can't focus light onto the retina and its point of focus is behind the retina. Most young children are longsighted but often grow out of it. Headaches after concentrated work are often a sign that someone is long sighted and may benefit from glasses.
 

What happens in long sighted eyes?


 


Astigmatism
This occurs when the front of the eye is shaped more like a rugby ball rather than a football. People who suffer from this type of refractive error may screw up their eyes or be sensitive to light.


 


Well..ini sahaja extra notes utk you all baca..ada banyak lagi bahan2 bacaan dalam website..search imej utk short or long sightedness..then pilih web yg anda suka..

See you all next week...with luv...bye!

Salam.

Hari nie..biarlah lirik lagu ini menerangkan segala-galanye..!! hayati dan fahamilah ia..!!

Glitter Words
[Glitterfy.com - *Glitter Words*]

Biarku menjadi lilin
Memberikan cahaya
Terangi sekeliling dengan diri terbakar
Tak siapa yang sedar
Disaat kegelapan rela aku berkorban
Demi satu harapan

Biar masa berlari
Dan kau terus mendaki
Aku tenang disini dengan sabar menanti
Tanpa dendam dan benci
Andainya kau terjatuh terluka dan tersungkur
Kurawat biar sembuh

Aku tak kan bertanya
Apakah nanti balasannya
Setiap pengorbanan setiap pemberian
Demi satu ikatan

Keikhlasan dihati
Walaupun kau ragui
Pada suatu masa dan suatu ketika
Akan ketara jua

Biarku menjadi lilin
Memberikan cahaya
Saat kau kesepian saat kau kegelapan
Kurela menerangkan

Aku senang begini dapat terus berbakti
Dengan cara sendiri
