EDUCATION SCIENCE mended writing on the fifth-grade science conceptions
1. the basic needs of the environment. such as air, water, space and food.
. plants and animals are ashore the surroundings they absence to prefer. another creatures above the surroundings has its own characteristic needs.
. All they will cause biological changes in the environment to survive.
. plants and animals, between animals and animals there is a very complicated relationship.
. biological and biological interdependence among, interaction and joint influence .
. among a definite scope of the being must live in harmony, the havoc of ecological balance and biological survival is threatened.
1-1 conditions.
1-2 growth requires one appropriate environmental conditions. When the environment changes when the plants have a certain ability to adjust to the environment.
1-4 5 interdependence, will form an ecological community.
1-7 >. the natural world of biological survival of a district have to manner a balanced and agreeable entire, the ecosystem.
2. >. favor the light so that objects can be called their light source.
. in the light irradiation the width of the shadow of the object,shanghai massage, direction, size and situation of the light source, direction, distance relative.
. the shadow of the shape and light source irradiated side of the fashion of the object.
. day, the sun, the shadow of the object will be the location with the level and direction of the sun is changed.
. just straight lines. stop light objects have shadows because light travels in straight lines occasioned.
. light objects encountered in the dissemination process, reflection occurs, the reflected light are straight lines.
. light reflection conviction widely secondhand in the production and life. Automotive mirror, periscope and so are the people the use of light reflection rule.
. a lot of light when the light is also peppery. the sun in Earth's largest light and heat.
. use of concave and convex lens converging light characteristics, can be light and heat. with in real life has been widely used.
. endothermic aptitude to object and object color, surface roughness and the angle of the sun on.
. Solar stamina is a kinds of clean energy, safe energy,I jotted drugs and stray cats, human are vigorously develop and use solar energy.
2-1 luminous object called a light.
. the length of the shadow object, the direction with the light location, direction is changed; objects the size of the shadow of objects and the distance between the light source; object shape and the shadow of the exposure light source the shape of the object side.
. obtain the object from different sides, the shadow of exposure is called projection, the projector is very serviceable in our lives.
2-2 the direction of the eclipse changes for the sun changes direction, the direction of the shadow and the sun is all the inverse.
. the sun changes the length of the object shadow in the sky as the sun changes position, the highest position of the sun shadow the shortest, lowest position of the sun, the longest shadow.
. It has long been known objects using the sun to decide the variation of the shadow of period.
2-3 fair straight lines.
2-4 br>. people use light reflection principle contrived many useful devices.
2-5 , but also brought us lukewarm. The sun is Earth's largest light and heat.
. light intensity on the tall temperature, low temperature to the cheap light.
2-6 hot relationship with the heat-absorbing, perpendicular object and the sun faster than the slant endothermic.
2-7 .
. solar water heater rendition and the materials, structure, use of the pertinent principles.
. product chart, no merely to consider the structure, but also consider the choice of materials, based on scientific principles, and how effortless practical.
2-8
. Earth's surface topography is constantly changing. Some of the slow process of change is carried out, but some is a relatively rapid process.
. weathering of the rock ambition eventually chance into the taint.
. made of rock weathering of soil that contains molecules of different sizes (small stones, sand, clay) and humus, water and wind.
. Soil and human production and life are closely related, as We cater a heap of resources.
. water, air, waves, glaciers and so the surface will produce erosion and deposition, and the formation of different landforms.
. land the size of the incline, with or without vegetation cover, rainfall size affects the value of the degree of soil erosion.
. human activities will change the surface morphology, such changes sometimes furniture natural calamities.
3-1 terrain includes highlands, mountains, basins, lakes, valleys, plains.
. Earth's surface rivers, oceans, mountains, plateaus and other different topography, the earth's surface is undulating, bumpy.
3-2 caused by the movement of the crust to form mountains, plateaus, rift and trenches and additional topographical traits.
. Earth's surface is rapidly changing and periodically raging, occasionally slow and imperceptible.
3-3 will change the see up carried out.
3-4 pebble, sand, clay), animal, plant remnants, and humus, water and air.
. water can carry soil particles flow forward with exercise, when the water still down, the material will be deposited to carry down. In general, the premier deposition of heavy particles, light particles after the deposition.
. biological life is inseparable from the soil, soil and human creation and life are closely narrated, it provides us with a cloud of resources .
3-5 3-6 topography, land detriment will also influence our production and living.
. conservation of forests, returning farmland to forest land can reduce erosion.
3-7 erosion of land formed.
. river will corrode the rill bed and the two sides, and take away the soil, where the flow is relatively slow, the soil will deposited.
. river erosion and sedimentation, the formation of a number of different topography.
3-8 activities are also changing the surface shape, we ought attempt to dilute land erosion.
4. can be measured and compared.
. Power has the size and instruction of the size of the coerce can be fathomed. power unit is and friction.
. friction contact surface size and smoothness, the weight of moving objects, movement pattern (rolling or sliding) on.
. friction sometimes salutary, sometimes adverse,shanghai massage, we may need to addition by or diminish it.
. to change the stationary or moving objects, the character must be lusty.
4-1 tension.
. certain force to the recess of the motorcar in film, the greater the traction, the faster car.
4-2 generated to restore the incipient shape of the force.
. stretch the rubber band the greater the effect of the longer, the greater the distance amusements car.
4-3 in the gas eruption, it will produce a boost in the opposite direction and the spray, called recoil.
. For motionless object in film, the object must be hard. to make objects push faster, the object must with a larger force.
4-4 surface friction, will produce friction.
. friction contact with the object size and the degree of surface smoothness: the smoother the surface, friction namely smaller; the rougher the surface,shanghai massage, the greater the friction.
. friction the size and heaviness of the object: the heavier the object, the greater the friction; objects lighter, smaller friction.
4-6 (rolling or sliding) on, because the same object, a small rolling friction, sliding friction large.
. manoeuvre of objects out of steam later that they will stop, and was due to the friction effect.
. pellet is rolling to sliding into the appliance.
4-7 sometimes need to increase the friction,shanghai massage, is sometimes required to decrease the friction.
4-8 and implementation of the agenda.
