ABSORPTION

Many objects in our daily life are made of different materials. Some of these materials can absorb water and some cannot. When we are wet, we need a towel to dry ourselves. Do you know other things which can absorb water ? Lets check them out ! 

LESSON 1 : Materials That Can Absorb Water

 Materials that can absorb water are called absorbent materials.
These are the examples of absorbent materials:



toilet paper





washing sponge









 

 



                                                                        handkerchief

 

 



pillows



cloth







                                                                  

How Can The Water Absorb In These Materials ?    

        This is how water absorb in the absorbent materials ( tissue  

          paper ).       

LESSON 2: Materials That Cannot Absorb Water

Materials that cannot absorb water that called non-absorbent materials. These are the examples of non-absorbent:      

glass

 



spoon

                       



umbrella



pebbles

rubber gloves

                                   

LESSON 3 : Why Is Absorption Important ?

The ability of some materials to absorb water is very useful in our daily life.

MAGNETS

LESSON 1 : Types of Magnets 
These are some of the different shapes of magnets.



bar magnet



cylindrical magnet



 

 



 

circular magnet

ring magnet



horseshoe magnet

 

U-shape magnet

Magnet has North pole and south pole. Letter "N" represent north pole and letter "S" represent south pole.


LESSON 2: Attract or Repel

When we put two magnets close to each other, they can either attract or repel each other.

Different poles of magnets attract. Same poles of magnets repel.

a) South pole repels South pole.
b) North pole repels North pole.
c) South pole attracts South pole.




LESSON 3: Handling Magnets

             



This is how we handle magnets properly.

LESSON 4: Magnets Attract Some Materials

Objects which are made of iron are attracted to magnets. They are called magnetic objects.
Objects which are not attracted to magnets are called non-magnetic objects.


 ( i )These are some examples of magnetic objects:
                                          
 

   

 

screws                                         sciccors










metal ruler

 

 

paper clips



  











These are the ways the magnets attract the objects:

                                               

( ii ) These are some examples of non-magnetic objects :

chopsticks

washing sponge

                                                

soft toy

                                                                         

pencils

plastic bottles

LESSON 5: Uses Of Magnets

Magnets are used in many things such as in refrigerator, pencil case and compass.

Magnetic strip is used to close the refrigerator door firmly.

The magnetic needles help to show directions in the compass.

The magnetic bar is used to close the pencil case tightly.

   
       

ANIMALS

LESSON 1: External Features Of Animals



An elephant has four legs,
a trunk , a pair of tusks and a pair of eyes.
It also has a pair of big ears and a big body.

A fish has a pair of eyes, a pair of fins and a tail.
It is also has scales covering its whole body.
It uses its scales to balance when it is swimming in the river and the sea.

A bird has a pair of eyes, a pair of wings and a pair of claws.
It also has a beak and a tail.
It has feathers covering its body.
It uses its wings to fly in the sky.

A goat has a pair of eyes, a pair of ears and a pair of horns.
It also has a tail and four legs.
It has hair covering its body.
It uses its horn to defend itself.

LESSON 2: Grouping Of Animals

Animals can be grouped according to their similarities.
a) animals groups by  four legs



cow

 

deer



 

 





   





  



dog



donkey



 





  



  






   

hippopotamus

   

elephant

                           

 A hippopotamus has four legs and it is also has horns. So, it can group by animal with four legs and animal which has horn.




b) Animals group by two legs


 

penguin

  





turkey

                
          






 

ostrich

             
 



 

eagle 


c) Animals group by scales 



fish

 


snake

 

           crocodile


 A crocodile has four legs and it is also has scales cover its body. So, it can group by animal with four legs and animal which has scales.
