Of different fruits (sesame, olive, Abu Kado)

Generations elementary school - summarize grade science winsteam third

The world of inanimate objects: - a term that includes all the things winsteam that do not belong to organisms such as air, water, table, book any products and materials that do not move or breathe and do not proliferate and do not feed and do not breathe and do not place a call.

Such as: Iron - Aluminum - Copper
When these materials Enkerb magnets These materials are attracted to magnets. Recipe we take advantage of the magnetic in several things, for example, winsteam to hang sheets on the fridge, in medicine also use magnets in getting iron fragment of the eye and in the magnetic compass needles we use to determine the north.
There are two types in the mixture or more of the materials, substances in the mixture keeps the characteristics. winsteam For example, when you combine winsteam the sugar with iron filings we have become a mixture of sugar and iron filings - sugar remains as it is and iron filings to remain as it is, but they Makhluttin.
Plants are living organisms such as animals and humans
Why are plants living plants breathe: they need air to live plants need food to live, it absorbs water and other substances from the environment and produce their own food by taking advantage of the sunlight. Plants grow and evolve: launches new twigs, leaves, flowers, fruits and seeds. Multiply winsteam plants: the plants winsteam evolve from new plants. Moving plants: Plants have the ability to move and grow as moving toward the light, and there are flowers blooming in the day and close at night. Plants are being contact: The launch of the smell of plants attract insects to it, by smelling plants winsteam send information tells the existence of insect winsteam food has.
If we look around us, we will find a lot of products that the man having produced "manufactured", we find all around us, all the time, for example, home, car, phone, food products, computer, clothes and tools to write all of these products is the man of the materials to their manufacture. These products are the rights winsteam to their manufacture of materials to meet their needs and solving their problems.
Need to use materials we manufacture a product to meet the need (problem) (a solution to the problem)
Materials around us, whether natural materials or artificial winsteam her qualities and characteristics that distinguish them from other Each item has its recipes winsteam are characterized by, for example, wood has a recipe float on the water, the glass transparent, salt dissolves in water, the iron has a recipe magnetic, metal conductive good heat, rock solid and strong ... ........
Ductility
We have to determine first four points, namely:
We are the sons of human materials we use to manufacture winsteam products to meet our needs and solve the problems facing us, but the use of these products and the exploitation of materials cause damage to the environment; we pollute the environment, winsteam harming organisms, succulent winsteam underestimate our health and natural materials ......
Materials such as:
Of different fruits (sesame, olive, Abu Kado)
Combustible materials - materials that are burning such as: wood, cloth
But at present, after the discovery of crude oil (black viscous liquid winsteam is present in the ground) extracted from human materials and fuel are many such as: gasoline, diesel fuel. Kerosene, natural gas, in addition to the coal mines of which Istkhrjohnh.
Materials and fuel, causing damage to the environment when it is burned to produce - soot, ash, smoke.

Open circuit, a circuit that does not allow the passage of the current and return to the power source (battery)
