Good Lifestyle

Science is the basis of human knowledge. Without this, you could think that the earth is flat and the sun is transported into the sky by a winged horse tank. There would be no ibuprofen, no electricity, no automatic plumbing. With regard to the subjects of the college, the remote and the furthest sciences have the greatest impact on everyday life. It's also probably your rusty.

Unless you work daily in search or in an affiliate domain, it's a good chance that you have completely forgotten all quarks and biomes and states of matter (there are four, in passing). The taxonomy of seven structures of terrestrial biology probably does not have a chance to recognize, either.

Yes, that's true: the science of the sixth year washard. So, how much do you remember? Scroll and discover. And for more ways to test your brain, give yourself to these30 questions you need to go through the 6th year.

It is important to know different types of energy sources and that they are renewable or non-renewable.

Fossil fuels come from the remains of prehistoric plants and millions of millions of years that have been buried under rock layers. They are a non-renewable resource and a day will be one day. And learn what could happen if we continue to use30 things that scientists say that scientists will occur if the population continues to grow.

Atoms are the smallest building blocks that make up all matter in the universe, insects and plants to stars and planets.

An atom is composed of a proton and neutron center called core, which is orbit by one or more tiny electrons,

Before this work of this scientist, the inhabitants of Europe have greatly believed that the earth was the center of the universe around which all the other planets and stars have turned.

Although Copernicus has published for the first time his work in 1543, it took about 200 years so that most Europeans think that the sun was the real center of our solar system. And for a more fascinating insight on the big beyond, do not miss these21 mysteries on space that no one can explain.

White light is not really white - it's a combination of all the colors of the rainbow.

When the light passes from one substance to another, for example, from the air in a prism, it refracts by changing the speed and the angle. Since different colors of light move at slightly different speeds, good prism can bend the white light in a way that makes the colors separated. And for an incredible scientific coverage, discover the20 types of artificial intelligence you use every day and you do not realize it.

Although "weight" and "mass" are sometimes used interchangeably in the conversation, in a scientific sense, there is a significant difference between them.

The mass is the amount of material in an object (usually shown in grams or kilograms) and the weight is the force that gravity exerts on a particular object (generally represented in books or ounces). If you were going to the moon, you weighed less - because there is less gravity, but your mass would remain the same.

Microorganisms can also be called microbes.

Microorganisms are living beings, but they are too small to be seen with the naked eye. They are very important for human life because, among other things, they do fertile ground and help us digest our food.

You will use these words in each class of science!

The scientific method is a great way to test ideas on how the world works. By doing so, you will also do a roadmap for any other scientist who wants to replicate your experience in the future.

Tip: The chlorophyll is brilliant green.

The plants need chlorophyll for photosynthesis or the process of manufacturing the usable energy of light.

The pH scale gives a measure of an acidity of a substance.

The scale of the pH changes from (the most acidic) to 14 (the most alkaline or basic), with 7 indicating a neutral substance such as water. A substance with a pH of the ammonia of powerful ammonia of 13 - is extremely alkali and must not be affected with bare hands.

The characteristics that help animals and plants survive the environments they live are called adaptations. They grow on several generations that the world around them changes.

The closure of nostrils, double eyelashes and bushy eyebrows all camels maintain the sand out of their nose, their eyes and mouths. While long layers could help camels to better reach their food, they are not direct adaptations to sand.

It is also the part of the brain responsible for our personality, our thoughts, our memories, behaviors and our judgment. It's a busy place!

The cerebellum helps us control our movements and postures, and the cerebral trunk controls the automatic functions of our body like breathing and heartbeat.

This process does not occur only to the ocean. It arrives wherever rocks and floors encounter water, weather conditions, animals or plants.

The transport of winds and water carry very small amounts of rocks and soil from one place to another. Although it is a natural process, human intervention can accelerate if we are not cautious.

When you combine two or more elements, the resulting substance may have different properties than one of the elements.

Water, carbon dioxide, chlorine and salt are all chemical compounds.

The Richter scale is logarithmic, which means that one is ten times more powerful than a 4.

The smallest earthquake we can really feel is a 2 at the Richter scale. A 4 is enough to make noise objects and 7 will cause major structural damage to buildings. The strongest earthquake recorded since the invention of the Richter scale was a QUAKE 9.5 which hit Chile in 1960.

Tip: The Earth also has two poles. Where are they?

The two ends of a magnet correspond to the two magnetic poles of the earth. The compasses are able to point north as a huge magnetic field envelope around the whole planet.

This term gives a general description of the weather of the area as well as its animal life and planting.

Scientists do not agree on the number of types, but some of the basic biomes include: the desert, the tundra, the rainforest, the forest with deciduous leaves and the meadows. If you hear a place described as a desert, even if you do not know where it is, you will know that it has extreme temperatures, small precipitation and very few animals or plants.

Every life on the earth is composed of cells. In fact, some are constituted only a cell.

The membrane of a cell is semi-permeable, which means that it is capable of allowing certain substances to move or exit (such as oxygen or water) while maintaining other substances.

There are four states or phases of material that we can observe in everyday life.

The four states of matter are solid, liquid, gas and plasma. In which state a substance depends on temperature and pressure. If these conditions change, a substance can transmit in a different state, such as liquid water evaporating in the water vapor.

The veins and arteries are part of the circulatory system that uses blood to transport oxygen and nutrients around the body.

The arteries carry the blood of the heart to the rest of the body to deposit its oxygen and the veins carry the deoxygenated blood in the heart to be pumped to the lungs for a refill. The oxygenated blood then rises to the heart to be pumped into the arteries and the cycle starts again.

The most common name for C6H12O6 is glucose, a type of sugar. You probably already know the molecular water formula: H2O.

Chemical formulas are a way of showing the type and number of elements that make up a molecular substance. The letters refer to the items on the periodic table and the numbers of the index indicate how many atoms of each element are.

There are millions of species on land and news are discovered all the time. Science holds a trace of these species and how they are linked to each other by taxonomy, a biological classification system.

Modern taxonomy is structured as a tree, where a kingdom is like the trunk and the divisions become smaller and smaller up to individual species. Many people remember these classifications and the order of the largest to the smallest with the mnemonic device "KengineerPHillipvsGermanToUtahFWheregoodsPaghetti. "The first letters of each word represent the first letters of each classification.

Most of the internal layers of the earth are solid, but some exist in a liquid state. Some recent studies suggest that liquid pieces actually turn faster than solid parts.

From the inside to the outside, the layers of the earth are the inner core, the outside core, the inner coat, the outer coat and the crust. And, although we can not pierce the exterior coat due to extreme heat and pressure, scientists have observed seismic waves to understand what the internal layers must do.

All types of animals and plants have a scientific name composed of two words, the first capitalized and the two writings in italics

The fancy term for the naming scientific system is the "binomial nomenclature", simply means that each type of creature get two names. The first is its kind (wider taxonomic group) and the second is its species. The most famous binomial name of all is a dinosaur:Tyrannosaurus rex.

There are 206 bones in the adult human skeleton. Fortunately, you do not need to learn all their names unless you go to medical school!

"Vertebra" is the plural of vertebra, one of the many bones that pip on the other to form the spine. These bones have a hole in the middle to allow the nerves of the spinal cord to pass.

Electricity is the flow of charged particles, usually electrons, through a substance. This means that the smallest subatomic particles can feed even the largest machines.

The most common conductors are different types of metals, although electrolytes, plasma and graphite also conduct electricity. Insulators include wood, plastic, glass and paper. They are important because they allow us to direct and work with electricity without being shocked.

The food chain brings energy from producers (usually plants) to primary consumers (usually herbivores), then secondary and tertiary consumers (omnivores or carnivores).

In this small food network, squirrels are primary consumers and foxes are secondary consumers. Poisoning Squirrels will affect the food chain of key consumers on Apex predators, including everything that could consume foxes. Disturb a link in a food chain also disrupts all the above.

The great tropical storms of the Atlantic Ocean are called hurricanes, while similar storms in the Western Pacific are called Cyclones. Same storm, different name.

While the winds of a hurricane quickly turn around a central point, does the air evade so that the clouds can not show up there. As a result, the center or eye of a hurricane is free of wind and rain.

If you are wondering, the diaphragm is located under the lungs and helps you breathe and go out.

The muscles you can control, like your language and biceps, are called voluntary muscles. The muscles that will continue to work even if you are not awake to control them, such as your heart and diaphragm, are called involuntary muscles.

Although Albert Einstein's special relativity theory showed that Newton's laws do not always work as you approach the speed of light, the three remain entirely in effect in the middle science class.

Also called the law of the uniform movement, this law allows you to know that no objects will change its speed (speed more direction) unless an external force does. The reason for a toy car, for example, stops even if it does not happen, it is the result of the air around it slow down until it stops.

Sound and bright travel in the waves and can bounce solid objects, create an echo (sound) or a reflection (light).

The light not only moves faster than his his turn faster than anything else in the universe we know. You can experience this in action during a storm, because you will see a lightning flash immediately, but the thunder that accompanies it will take a few seconds to catch up. And if they did not fear your brain, try your hand at the30 questions you would need ACE to spend the 6th mathematical year.
