MAGNETISM

Have you ever played with a magnet? If you have, i will know that it picks up things like paper clips and drawing pins, pulling them with the force of magnetism. I may have noticed that a magnet will only pick up certain things, mostly ones made of iron or steel. Magnets are usually made from iron because iron is the only common metal that is magnet.

Magnets do not always attract, or pull things towards them. Sometimes they repel things, or push them away. I can make this happen if i have two magnets. If i bring one end of the first magnet up to one end of the first magnet up to one end of the second magnet, the ends will either stick together (attract) or fly apart (repel).

Take one of your magnets and hang it from one piece of cotton tied round the middle. Do this several times. What happens? I should find that it always points in the same direction when it stops moving. One end points to the north, and the other to the South. We call the north-pointing end of a magnet, its north pole, and the south-pointing end, its south pole. It seems as if the earth has magnets at its north pole and south pole, which attract your magnet.

Wherever you go on Earth, you find that a swinging magnet always ends up pointing north and south. So if you carry a magnet about with you, you can can always tell which way is north. An easier way to do at this is to use a compass.

Gravity

The gravity of the world is very powerful. That is why it is difficult to get into Space. The space shuttle beats gravity by having very powerful rocket engines. They make it grow very much faster than a rifle bullet. In Space, it travels hundreds of kilometres every minute.

What happens when i throw a ball into the air? It goes up a little way and then falls back to the ground. When apples are ripe, they fall of a tree. If i jump up in the air, i soon come down again. Something is pulling you, the ball and the apple back to the ground. It is a force i call gravity. Gravity keeps people in the ground, the waters in the oceans, and the air in the atmosphere. It also goes out a long way in Space. It even keeps the Moon in place thousands and thousands of kilometres away!

Up in Space, astronauts do not seem to be affected by gravity. They feel weightless and just float about like this astronaut in the space shuttle's cargo bay.

It is gravity that gives me my weight. Weight is force with which the Earth pulls my body. It is not the same as my mass. Mass is the amount of a stuff in my body. This never changes. But my weight can change, if gravity changes.

If i went far out into Space, i would find that i seem to be weightless! I would just float about as if there was no gravity. Gravity is still there, but its pull on my is tiny because of the way my are travelling in Space.

Engines

At first people used their own strength to work the machines they built. Next they used animals. Then they found out how to use the power of the wind when it blows, and of water when it flows. They built machines to catch this power stores as engines to work their other machines. This power 'catchers' were the sails and waterwheels which drove the mills.

Soon people found out how to make steam work their engines. Steam engines were very powerful and could be used anywhere to drive bigger and better machines. Some steam engines were use in the first cars. But today our cars have a much more powerful engine, the petrol engine. It uses petrol as fuel. The engine uses the energy from burning petrol to turn the car wheels.

The petrol engine has hundreds of different parts. There are several pistons and cylinders. The petrol burns in the tops of the cylinders and make hot gases. The hot gases push the pistons down. This movement makes a rod, or shaft, turn. Then gearwheels and other shafts carry the movement to the wheels.

We use other kinds of engines to turn the machines that make our electricity. One spins when water flows through it and is called a water turbine.

Simple Machines

I use hundreds of different machines to help us with my work. Machines help us travel, farm the land, make things for us, type my letters, wash my clothes. Machines put forces to work. They help us to do things more easily and usually quickly. t is much faster to sew a dress with a sewing machine than it is by hand. Most machines are driven by engines or electric motors.



Some machines are very simple indeed. I use a hammer as a machine when i take out a nail with the prongs on its head, because me are using the hammer as a lever, which is one of the simplest machines. I often use levers to apply extra force to something. Garden spades, tweezers, and pliers are all kinds of lever. I use them as machines to help me do something more easily.


The screw and wedge are other simple machines. I can easily turn the screw of a workshop vice to make it grip something tightly. An axe has a head shaped like a wedge. The wedge has a thin edge to go into the wood easily, and then the sides of the wedge force the wood outwards so it splits.

Other simple machines use wheels. A pulley is a wheel with a rope running over it. By fastening loads to pulleys, i can make it easier to lift heavy things. I just have to pull on the other end of the rope. Another wheel machine is the wheel and axle, which is like a pedals and chain wheel on a bicycle.

I can make my bicycle go on pushing the pedals. A chain carries the force of my pedalling to the axle of the back wheel, and turns it round. The chain joins a gear wheel on the pedals to a smaller one on the back wheel. This smaller wheel turns faster than the pedal gear, and that makes my pedalling turn the bicycle wheel faster.

Happy Mother's Day

Don't Forget To Wish The Moms in Your Life "Happy Mother's Day" This Sunday!

M ... is for the million things she gave me,
O... means only that she's growing old,
T... is for the tears she shed to save me,
H... is for her heart of purest gold;
E... is for her eyes, with love-light shining,
R... means right, and right she'll always be.

Put them all together, they spell "MOTHER,"
A word that means the world to me.



Dear Mom,
Who is my mom? Is she good or bad? My Mom is ROSALITA G. MORENO. No.
She lways here to me. If i have a problem there is she. She love me so much. And She Love her so much.
Is she is important to me? Yes, because she is beside to me to all. She carry me when i was a baby AND now, there is she.. My only one MOTHER.

Forces at Work

Put a ball on the table so that it keeps still. If i don't touch it, it will stay where it is, and it will only start to move when i push it. A cart will stay on a flat place until a horse or tractor pulls it, then it starts moving. These pulls and pushes are called forces, and forces make things move. They can also all things down and stop them moving. When i put on the brakes on my bicycle, me airs applying forces to the wheels, which try to stop them moving.

In general, things are still stay still, and things that are moving stay moving, and it is hard to make them change. I say that they have inertia. I can use a big bowl full of water to show inertia. Put it on the ground outside and suddenly push the bowl hard. I will find that bowl moves, but the water inside stays there. Then what happens?

When i roll a table-tennis ball gently along the carpet, i find that it goes so far and then stops. Some force must be making it slow down. It is a force i call friction. There is friction when any objects moves and rubs against another. Rough surfaces have a lot of friction; Try rolling your ping-pong ball along a smooth floor to see how far it goes.

Friction also makes heat. I can find this out by rubbing my hands together.

Colour

In our colourful world, the commonest colour is green. Almost all plants have green leaves to help them make their food. Flowers may be any colour i can think of, and often then bright colours attract insects. Things i buy come in colours of all kinds, because the people who make them with dyes or paints to make them look nicer. Do i have a favourite colour?
Where do colours come from? The light that comes from the Sun is yellowish-white, but all the different colours i see are already in sunlight. This is because sunlight is really a mixture of all the colours of the rainbow. When sunlight splits up into its colours as it passes through raindrops, all the colours separate into a rainbow.

Here i see all the colours of the rainbow. There are seven colours from top to bottom. They are red, orange, yellow, green, blue, indigo, violet.
This explains why thing are coloured. I see a fire engine when sunlight is reflected from it into our eyes, but the paint covering the life engine takes in, or absorbs, all the colours in the sunlight except red. The red colour is reflected from the paint into my eyes, and i see the fire engine as red. White things reflect all the colours.

Not everyday can see colours properly. Some people cannot tell the difference between green and reds, or blues and yellows. Dogs and many other animals can't see any colours at all.
