CATCHING THE PARTICLES PRESENT IN AIR!

Let's make a device to catch the particles in the air!!


Materials:


A microscope or a magnifying glass


Elastic Band


A paper tissue


Empty Glass Jar

Instructions

Slightly damp the tissue paper in water.

Attach the damp tissue paper on the empty glass jar

Go outdoors and set the jar at a high, open and windy place, and leave it there for a day.

Then bring it inside and examine the tissue paper with a microscope or a magnifying glass.

The tissue will have collected various bits and pieces of

material. Some, like pollen from flowers, will be natural. 

Others, like particles of soot, will be artificial waste products.

You can try this experiment in different weather condition!

TO INFLATE A BALLOON USING VINEGAR AND BAKING SODA!

Let's use vinegar and baking soda to blow a balloon!!


Materials:


A balloon


Water


Baking soda


Lemon juice or a lemon (vinegar works best)


Drinking straw


Small soda bottle (12 ounce or 20ounce)

Instructions

Take the small balloon in your hands and stretch it out a bit to make it a little easier to inflate.

Pour about 1 ounce of water of into the bottom of a small baking soda

Dissolve 1 teaspoon of baking soda into the water with the help of drinking straw.

Pour 3 tablespoon of lemon juice or the lemon juice found in 1 lemon.


Quickly put the mouth of the stretched balloon over the mouth of the soda bottle.

  What is happening???

The balloon slowly inflates due to the presence of carbon-dioxide formed by the reaction of water, baking soda and lemon juice/vinegar
