Nothing Gold Can Stay - Poem by Robert Frost

Nothing Gold Can Stay


     - by Robert Frost

Nature's first green is gold, 
Her hardest hue to hold.

Her early leaf's a flower;
But only so an hour.

Then leaf subsides to leaf.
So Eden sank to grief,

So dawn goes down to day.
Nothing gold can stay.

A Patch of Snow - Poem by Robert Frost

A Patch of Snow


      -  By Robert Frost

There's a patch of old snow in a corner
That I should have guessed
Was a blow-away paper the rain
Had brought to rest.

It is speckled with grime as if
Small print overspread it,
The news of a day I've forgotten --
If I ever read it.

Dust Of Snow - Poem by Robert Frost

Dust Of Snow

    - By Robert Frost

The way a crow 
Shook down on me
The dust of snow
From a hemlock tree.

Has given my heart
A change of mood
And saved some part
Of a day I had rued.

How to Make a Solar Water Purifier for Science Project

School projects demand various models and devices to be made. This could be for festivals, art or science activity. Making Solar Water Purifier is one such science project kids are asked to make. The following DIY science project of solar water purifier is a simple activity made with materials easily available at home. Kids can easily make it and present it in school as part of a DIY project or even as a activity to understand how solar power works!


Material for making a Solar Water Purifier


Large bowl - 1
Glass cup - 1, shorter than the bowl
Cling wrap / plastic wrap
Cellophane tape
Water - 2 glasses
Salt - 1 tsp
Spoon
Coin or a pebble

Method for making a Solar Water Purifier

1


Pour two glasses of water in a large bowl and add salt to it. Allow the salt to dissolve completely by stirring with a spoon.

2


Place the small glass cup in the center of bowl. Make sure that the glass cup is taller than the water level in the bowl.

3


Cover the bowl with the cling wrap completely and seal the edges with a cellophane tape. See that the edges are tightly sealed.

4


Place the coin or the pebble right on the top of the cling wrap exactly over the small cup.

5


Place this bowl in area of direct sunlight, near a window or on a balcony for several hours.

6


Once done you will find that water is collected in the glass cup. Open the wrap and taste the water! This process of purification can also be tried with sea water as a part of science project.

How this works?


The solar purifier works with the concept of evaporation and condensation. When the salt water is placed in the sun, it gets evaporated. Thus due to evaporation the water converts into vapors and salt deposits back in the bowl. But these vapors when rise to move out of the bowl, get trapped due to the cling film and condense into water droplets. These water droplets gather towards the weight, i.e. the pebble or the stone and gall and get collected in the glass cup.

A Minor Bird - Poem by Robert Frost

A Minor Bird


         - By Robert Frost

I have wished a bird would fly away,
And not sing by my house all day;

Have clapped my hands at him from the door
When it seemed as if I could bear no more.

The fault must partly have been in me.
The bird was not to blame for his key.

And of course there must be something wrong
In wanting to silence any song.

How to Make a Simple Solar Oven at Home - DIY Science Projects for Kids

Making a solar oven with a pizza box is one of the simplest way of trying your hands on creating a DIY Science project of simple solar oven. It is a fun experiment which can help your kids enjoy summers by making and testing the solar oven out on a hot day! The simple solar oven is made with materials which are easily available at home and the kids can easily make them by following instructions and being careful with sciessors.

Materials for making a Simple Solar Oven


Large Pizza box - 1, if not available than a cardboard box would do!
Pencil
Big Ruler
Aluminium foil
Chart paper (black color)
Cling wrap / plastic wrap
Transparent Plastic bag
Scissors

Method for making a Simple Solar Oven


1


Draw a square on the flap of the pizza box by leaving at least an inch of space from the edges on the sides of the flap.

2


With the help of the scissor or a cutter cut along the three sides of the square leaving the top side folded along the uncut lines. With help of glue, line the folded flap with an aluminium foil. This aluminium foil would work as a reflector. You could also line the aluminium foil and fold the edges which could then be sealed with cellophane tape.

3


Place and line the insides of the pizza box with an aluminium foil, leaving no gaps throughout. Once done, cover it with a chart paper.

4


Place on this a transparent plastic bag on which you could place the plate in which food can be warmed.

5


Cover the window which was made by cutting the square on the top of the pizza box with two layers of the cling wrap.

6


Place the simple solar oven in a place which receives direct sunlight. Adjust the reflected such that maximum sunlight would reflect off the foil.

7


Test you simple solar oven by trying to melt butter or cheese on a bread slice. Once successful try other foods. The process of using this simple solar oven takes a longer time to cook and hence some patience is required on your part! But always remember that this way of cooking is about using a clean source of renewable energy and hence one should be proud of the results!

How this works?


The energy that is radiated from the sun is harvested by the solar oven to cook food. The aluminium foil lined on the flap works as a reflector and reflects the rays of sun directly on the are where food is placed. The black chart paper absorbs the heat and the plastic sheet placed beneath the food plate helps to retain the heat and cook.

Fire And Ice - Poem by Robert Frost

Fire And Ice

                - By Robert Frost


  Some say the world will end in fire,
  Some say in ice.
  From what I've tasted of desire
  I hold with those who favor fire.

  But if it had to perish twice,
  I think I know enough of hate
  To know that for destruction ice
  Is also great
  And would suffice.
