Yesterday and today A poem by Vasu Mittal VI H

just yesterday it seems,
the fields were full of grains,
just yesterday,the water,
came from heaven,
and the earth was not a thirsty,
but yesterday is five years gone,
and today is nought but rubble,
a wilderness of earth,
baked brown by the relentess,
desert sun..............................

Manmeet Kaur's poem

IT'S CHANGE


Mum i don't want to go to school today,
cause i fear our world is in decay.

I feel my teachers are part of the plot,
I'm the only one who sees through the rot.

Scientists are cloning pigs & sheep,
saying it's change-a quantum leap.

Biologists are making stem cells grow,
saying it's change - the way to go.

Geologists are finding cracks in our earth,
saying it's change - predicting it's birth.

Archaeologists are digging up fossils & bones,
saying it's change - time for clones.

Yes, scientists are causing me great concern,
giving us kids much to learn.

A poem by Megha Panjwani

Save the Environment

Save the environment,
To save yourself,
It is waste management,
That needs many arrangements.
Dispose all the waste,
To keep ourselves safe,
Use the twin-bins,
Which helps the cleanliness to win.
Keep the environment clean,
Think for the environment, what are you being,
Solid, Liquid & Gaseous wastes,
Make the environment so dirty.
We should take some safety measures,
To keep ourselves away from all the cunning garbage,
This waste management gives us the lesson of cleaning,
Makes our habit of daily cleaning.
Waste management is the part of environment,
It is stored inside the garbage department,
We have many duties for saving this green world,
We should follow each and control the extinction.
Waste management has a concept of garbage,
Explains the whole waste management package,
So this was the whole waste management and some safety arrangements,
So let’s start saving the precious environment.
Save the environment,
Save the environment……………..

weight management for kids

Health and Fitness Management for the students
A few guidelines by a science teacher!


At breakfast always offer some fruit with breakfast cereals or offer diluted fruit juice as a drink.

With cooked breakfasts include some mushrooms, tomatoes or baked beans.

Always offer at least one vegetable and one fruit at lunch and supper.

Crunchy raw vegetables such as carrot sticks and cucumber slices are popular in lunch boxes and with cold meals.

For simple puddings, serve fruit with yogurt, custard or ice cream.

Younger children often eat more fruit when it is cut up for them.

Choose cooked puddings containing fruit, eg fruit crumbles, tarts and souffles.

If serving cake or biscuits always serve them with some pieces of fruit Drinks.

Milk and water are the best drinks for children as they do not damage teeth.

Fruit juices are acidic and, although they provide nutrients, they can damage tooth enamel when offered between meals. Offer them well diluted at meal times to avoid this.

Sugary, fizzy drinks and squashes are also acidic and give calories but virtually no nutrients. Given frequently between meals they cause tooth decay.

Children’s appetites vary from day to day depending on how they feel and how active they are so keep an open mind on how much they will eat. Let them decide.Always offer 2 courses at lunch and supper – a savoury course and a pudding. This gives 2 opportunities for children to eat nutritious foods.

Children eat better when there is a routine of 3 meals with 1 or 2 nutritious snacks each day. Do not allow grazing on food throughout the day. It is important for children to feel hungry before a meal and then learn that feeling of having had enough and not needing any more.

Many overweight children have no idea when they feel comfortably full as they tend to graze on snacks throughout the day and have little experience of when they are hungry and when they are not. tites vary from day to day depending on how they feel and how active they are so keep an open mind on how much they will eat.

Building a periscope

REQUIREMENTS
• Two 1-quart milk cartons
• Two small pocket mirrors (flat, square ones work best)
• Utility knife or X-Acto knife
• Ruler
• Pencil or pen
• Masking tape

Use the knife to cut around the top of each milk carton, removing the peaked "roof."

Cut a hole at the bottom of the front of one milk carton. Leave about 1/4 inch of carton on each side of the hole.

Put the carton on its side and turn it so the hole you just cut is facing to your right. On the side that's facing up, measure 2 3/4 inches up the left edge of the carton, and use the pencil to make a mark there. Now, use your ruler to draw a diagonal line from the bottom right corner to the mark you made.

Starting at the bottom right corner, cut on that line. Don't cut all the way to the left edge of the carton-just make the cut as long as one side of your mirror. If your mirror is thick, widen the cut to fit.

Slide the mirror through the slot so the reflecting side faces the hole in the front of the carton. Tape the mirror loosely in place.

Hold the carton up to your eye and look through the hole that you cut. You should see your ceiling through the top of the carton. If what you see looks tilted, adjust the mirror and tape it again.

Repeat steps 2 through 6 with the second milk carton.

Stand one carton up on a table, with the hole facing you. Place the other carton upside-down, with the mirror on the top and the hole facing away from you.

Use your hand to pinch the open end of the upside-down carton just enough for it to slide into the other carton. Tape the two cartons together

Now you have a periscope! If you look through the bottom hole, you can see over fences that are taller than you. If you look through the top hole, you can see under tables. If you hold it sideways, you can see around corners.


Periscope comes from two Greek words, peri, meaning "around," and scopus, "to look." A periscope lets you look around walls, corners, or other obstacles. Sub-marines have periscopes so the sailors inside can see what's on the surface of the water, even if the ship itself is below the waves.
