WALKING WATER

              WALKING WATER

Materials Required:

Tissues

Glasses

Food dyes

Water

Introduction :

     This is an experiment which explains the capillary action and how the water walks from one glass to another. 

Procedure:

Step -1:

              Take 5 glasses and pour water.                       into 1, 3 & 5 glasses and leave the                 other glasses empty .

Step-2:

Add different food colours in water in the glasses.

Step-3:

       

Fold the tissue paper and immerse the tissue paper half in the first glass connecting the second glass and so on.. 


Step-4:

             After few minutes we can                             observe the water being                                  absorbed     by the tissue.

Step-5:

     

After some time we can observe the water walking i. e; passing through tissues from the one glass to the other glasses i. e;  empty glasses..

WATER RISING EXPERIMENT

          WATER RISING EXPERIMENT

Introduction :

     This is an experiment  which explains how the water rises when the candle puts off.

Materials Required :

Glass or tumbler

Candle

Tray

Food colour

Procedure:

Step-1:
              Pour  some water into the plate and               add some food colour in water..
Step-2:

Place the candle in centre of the plate in water and lit up the candle.
Step-3:

Invert the container on the candle.

Step-4:

         The candle puts off  and the water rises up into the container.



Conclusion :

     This happens because, when we cover the lit of the candle, it heats the air inside the container.The heated air expands and tries to come out. when the flame puts off the air in the container starts cooling down. As it cools the air contracts inside the container and pulls the water from outside the plate into the inverted container. In 5-10mins the water completely rises into the container.

Oxygen is needed for burning

           OXYGEN IS NEEDED FOR                                  BURNING.

Introduction :

        This is an experiment to show how oxygen is needed for things to burn.

Materials Needed:

Glass

Plate or tray

Candle

Procedure:

Step-1:

              Take a candle and place it in a bowl.

Step-2:

                 Now light the candle and let it burn for few seconds.

Step-3:

Cover the candle with an inverted glass.



             We can observe that the candle blows out after some time.


Conclusion :

            Oxygen helps in burning. when the oxygen inside the glass is used up.,the candle puts off and the  candle which wont be covered still  going on burning due to the  presence of Oxygen.

Absorption by Roots

        Absorption by Roots

Introduction :
 
          By this experiment, we can show how the absorption takes place  in the plants through roots.

Materials Needed:

 Carrot,  A glass of water, Blue food dye

Carrot

Blue food dye

Water

Procedure:

Step-1:

            Pour water into the glass and add some blue food dye into the water.

Step-2:

         put a carrot in the glass of water.

Step-3:

          Leave the carrot in water for some.          days. 

Step-4:

          Then cut the carrot into half length wise and look inside the carrot.
     We can observe the blue colour inside the carrot.

Conclusion :

           The blue coloured water is absorbed by the carrot from the tip of the carrot to the  up and inside of the carrot changes into blue colour.

🌈 RAINBOW ROSES 🌈

                      🌈   RAINBOW ROSES 🌈 

       

Introduction :

              In this experiment,  we will see how the conduction in stem takes place  and how the  Flower changes its colour.

Materials needed:

White flowers

Food colours

Water

 Procedure

step-1:

         pour water  into the glass and add.                some red food colour ln water.             and stir it well.
Step-2:

           Now the cut  the  stem of the.                   flower into the  half(lengthwise).
step-3:

            Slowly, the stem of the flower starts absorbing the red coloured water.

        If we observe, after one day  the  flower changes into red colour.

Conclusion :

The change in the  colour of the flower shows the  conduction  in stem and how the plants or the flowers absorb the water or the minerals from the soil. 

INSTANT SNOW EXPERIMENT

          INSTANT  SNOW EXPERIMENT   

     

 Introduction :
             This is an experiment for kids,they love and enjoyy a lot by doing this experiment.

Materials Needed:

Glass

SAP

Water

Procedure:

Step-1:
            SAP is nothing but super Absorbent.              Polymer ,which we can get from the.              kids diapers.
Step-2:
     
           Take a transparent drinking glass                   and put some SAP into the glass.
Step-3:

          Pour water into the glass. SAP bulges.
          And increases 90% more. And it                      looks same like SNOW.

TEST FOR THE PRESENCE OF SUGAR

     TEST FOR THE PRESENCE OF                            SUGAR

          

Introduction :

    By doing this experiment  we can know the food item which we eat contains how much the sugar content is...

Materials  Needed:

Test tube

Dropper

Benedict's solution 

Procedure:

Step-1:
Take a small amount of food sample, crush if the food sample is in solid form and put it in the test tube.

Step-2:
Add some water to test tube and shake it.

Step-3:
Add a few drops of Benedict's solution to the test tube. Heat it for about  one minute.

                   We can observe the changes occur depending on the sugar content present  in the taken food sample.
         Actually the Benedict's solutuon will be blue in colour
          

 If the food sample contains low sugar content it turns into green colour. 
  If the food sample contains medium sugar content it turns into yellow colour. 
    If the food sample  contains high sugar  content  it turns into brick-red colour.

Conclusion :
  The change in colour confirms the presence of sugar.
