 UNIT 6 : WOMEN INVENTORS

UNIT 6 : SARAH BOONE AND JOHN ALBERT BURR

Dressmaker Sarah Boone made her name by inventing an improvement to the ironing board in 1892 that would make it easier to press sleeves without introducing unwanted creases.  In her patent application, she wrote as quoted by biography.com that the purpose of her invention was “to produce a cheap, simple, convenient and highly effective device, particularly adapted to be used in ironing the sleeves and bodies of ladies’ garments.”

On May 9, 1899, John Albert Burr patented an improved rotary blade lawn mower. Burr designed a lawn mower with traction wheels and a rotary blade that was designed to not easily get plugged up from lawn clippings. John Albert Burr also improved the design of lawn mowers by making it possible to mow closer to building and wall edges.

UNIT 5 : EXPERIMENT ABOUT REFRACTION

When we look at a straw in a glass of water, the straw appears to bend when it hits the water's surface. This is because water and air have different densities.

UNIT 5 : CONDUCTORS AND INSULATORS

Thermal insulators don't transfer heat very effectively. Materials such as wood, wool and plastic are good thermal insulators.

Thermal conductors  are materials that can transfer heat quickly and effectively. Metals such as iron, copper and aluminium are good heat conductors.

UNIT 5:  LIGHT PROPERTIES: REFLECTION AND REFRACTION


Reflection  occurs when light hits an object and bounces back.
Refraction occurs when light changes direction because it passes from one substance to another.

STEPHEN HAWKINS

Last Wednesday we lost one of the most important scientists in the world: Stephen Hawking. He studied the black holes and continued with the studies of Albert Einstein. Here is one of his quotes.

El último miércoles perdimos a uno de nuestros científicos más importantes: Stephen Hawking. Estudió los agujeros negros y continuó con los estudios de Albert Einstein. Aquí os dejo una de sus citas:

"Remember to look up at the stars and not down at your feet . Try to make sense   of what you see  and wonder about  what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up."

UNIT 5 : ISAAC NEWTON

Isaac Newton was born in 1643 and became famous for his work on gravity and his three laws of motion. He was also well known for his work on light and colour, and what is now called calculus (a branch of mathematics).

Isaac Newton nació en 1643 y fue famoso por su trabajo sobre la gravedad y las tres leyes del movimiento. También fue conocido por sus trabajos sobre la luz y el color, y por lo que ahora llamamos cálculo (una rama de las matemáticas)

UNIT 4 : NON - RENEWABLE ENERGIES


Non- renew able energy sources are limited. It is practically impossible to regenerate them. Fossil fuels  and uranium  are non renewable energy sources.

FOSSIL FUELS : COAL AND OIL

Coal is a non renewable and a pollutant but it produces large quantities of energy.

UNIT 3 : THE BIOSPHERE

                        "  All things are connected like the blood that unites us all" 

Here you have the letter that Chief Seattle sent to the President of the United States saying what he thought about the land where they lived and the idea of selling and leaving their land.  Here is the key of our lesson " All creatures are interconnected"

CHIEF SEATTLE'S LETTER

"The President in Washington sends word that he wishes to buy our land. But how can you buy or sell the sky? the land? The idea is strange to us. If we do not own the freshness of the air and the sparkle of the water, how can you buy them?
Every part of the earth is sacred to my people. Every shining pine needle, every sandy shore, every mist in the dark woods, every meadow, every humming insect. All are holy in the memory and experience of my people.
We know the sap which courses through the trees as we know the blood that courses through our veins. We are part of the earth and it is part of us. The perfumed flowers are our sisters. The bear, the deer, the great eagle, these are our brothers. The rocky crests, the dew in the meadow, the body heat of the pony, and man all belong to the same family.
The shining water that moves in the streams and rivers is not just water, but the blood of our ancestors. If we sell you our land, you must remember that it is sacred. Each glossy reflection in the clear waters of the lakes tells of events and memories in the life of my people. The water's murmur is the voice of my father's father.
The rivers are our brothers. They quench our thirst. They carry our canoes and feed our children. So you must give the rivers the kindness that you would give any brother.
If we sell you our land, remember that the air is precious to us, that the air shares its spirit with all the life that it supports. The wind that gave our grandfather his first breath also received his last sigh. The wind also gives our children the spirit of life. So if we sell our land, you must keep it apart and sacred, as a place where man can go to taste the wind that is sweetened by the meadow flowers.
Will you teach your children what we have taught our children? That the earth is our mother? What befalls the earth befalls all the sons of the earth.
This we know: the earth does not belong to man, man belongs to the earth. All things are connected like the blood that unites us all. Man did not weave the web of life, he is merely a strand in it. Whatever he does to the web, he does to himself.
One thing we know: our God is also your God. The earth is precious to him and to harm the earth is to heap contempt on its creator.
Your destiny is a mystery to us. What will happen when the buffalo are all slaughtered? The wild horses tamed? What will happen when the secret corners of the forest are heavy with the scent of many men and the view of the ripe hills is blotted with talking wires? Where will the thicket be? Gone! Where will the eagle be? Gone! And what is to say goodbye to the swift pony and then hunt? The end of living and the beginning of survival.
When the last red man has vanished with this wilderness, and his memory is only the shadow of a cloud moving across the prairie, will these shores and forests still be here? Will there be any of the spirit of my people left?
We love this earth as a newborn loves its mother's heartbeat. So, if we sell you our land, love it as we have loved it. Care for it, as we have cared for it. Hold in your mind the memory of the land as it is when you receive it. Preserve the land for all children, and love it, as God loves us.
As we are part of the land, you too are part of the land. This earth is precious to us. It is also precious to you.
One thing we know - there is only one God. No man, be he Red man or White man, can be apart. We ARE all brothers after all."
