What Is Energy?
The simplest definition of energy is "the ability to do work". Energy is how things change and move. It's everywhere around us and takes all sorts of forms. It takes energy to cook food, to drive to school, and to jump in the air.

Forms of energy 

Kinetic Energy

Kinetic Energy is energy that is in motion. Moving water and wind are good examples of kinetic energy. Electricity is also kinetic energy because even though you can't see it happen, electricity involves electrons moving in conductors.

Potential Energy

Energy is measured in the amount of "work" it does. Potential Energy is stored energy. Examples of potential energy are oil sitting in a barrel, or water in a lake in the mountains. This energy is referred to as potential energy, because if it were released, it would do a lot of work.
Energy can change from one form to another. A good example is a Roller Coaster. When it is on its way up, it is using kinetic energy since the energy is in motion. When it reaches the top it has potential (or stored) energy. When it goes down the hill it is using kinetic energy again.

Other Types of Energy

There are other types of energy as well:
  • Mechanical Energy is the energy of motion that does the work. An example of mechanical energy is the wind as it turns a windmill.
  • Heat energy is energy that is pushed into motion by using heat. An example is a fire in your fireplace.
  • Chemical Energy is energy caused by chemical reactions. A good example of chemical energy is food when it is cooked.
  • Electrical Energy is when electricity creates motion, light or heat. An example of electrical energy is the electric coils on your stove.
  • Gravitational Energy is motion that is caused by gravity. An example of gravitational energy is water flowing down a waterfall.
  •  Light - Light is called radiant energy.The Earth gets a lot of its energy from the light of the Sun. 
  •  Motion - Anything that is moving has energy. This is also called kinetic energy. 
  • Nuclear - Huge amounts of nuclear energy can be generated by splitting atoms.

Light

What is light?

When we're very young, we have a very simple idea about light: the world is either light or dark and we can change from one to the other just by flicking a switch on the wall. But we soon learn that light is more complex than this.
Light arrives on our planet after a speedy trip from the Sun, 149 million km (93 million miles away). Light travels at 186,000 miles (300,000 km) per second, so the light you're seeing now was still tucked away in the Sun about eight minutes ago. Put it another way, light takes roughly twice as long to get from the Sun to Earth as it does to make a cup of coffee!




Why are there different colours of light?
There are different colours of light because they are light waves which have different wavelengths. Red light has the longest wavelength while violet light has the shortest wavelength.

What are the primary colours of light?
Red, green and blue are the primary colours of light. Mixing them in various ways will make all other colours, including white.

What is reflection?
The bouncing back of light waves when they hit an object with a very smooth and shiny surface, like a mirror, is called reflection.

What is refraction?
The bending of light as it passes from one transparent substance to another, like air to water, is called refraction.

What makes a rainbow?
When sunlight is intercepted by a drop of water in the atmosphere, some of the light refracts into the drop, reflects from the drop's inner surface, and then refracts out of the drop. The first refraction separates the sunlight into its component colours, and the second refraction increases the separation. The result is a rainbow.

Heat 

Heat Transfer
Learn about heat transfer and how to keep things warm by testing the characteristics of different materials with this fun activity for kids. Some materials are good thermal conductors, easily letting heat pass through them, while others are good thermal insulators, not easily letting heat pass through them. Conduct experiments and watch how the temperature changes. Record your results on a table and make your own conclusions, some materials help keep things warm while others make them go cold quick. Find out if metal, cardboard and polystyrene are good at thermal insulation or have good thermal conductivity by checking out this heat transfer activity.

6º. Unit 6.MATTER

MATTER IS ANYTHING THAT OCCUPIES SPACE



Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. If you are new to the idea of mass, it is the amount of stuff in an object. We talk about the difference between mass and weight in another section. Matter is sometimes related to light and electromagnetic radiation.

PHYSICAL CHANGES

 A physical change is a change in which no new substances are formed. Physical changes affect the form of a chemical substance, but not its chemical composition. Mixtures can be separated into their parts by physical methods, such as spinning in a centrifuge. but can not usually be used to separate compounds into chemical elements or simpler compounds.

Most physical changes are reversible. Examples: changes of shape, changes of states, passing electricity through a copper wire. Some physical changes are melting, freezing, boiling.





CHEMICAL CHANGES

We say there us a chemical change in a matter when the internal make-up (molecules) of the object changes. Unlike a physical change, chemical changes cannot be reversed. Changes that cannot be reversed are called Non-reversible Change.
There are usually one or more new substances formed or created from that change. You can tell there is chemical change when it produces a gas, light, smell, fire (heat) or color change. A chemical change may also be accompanied by the formation of a solid in the form of a precipitate, and in some cases, accompanied by a gain or loss of energy.
A good example is the change that occurs when you fry an egg:

SEPARATING MIXTURE
The different substances in mixtures are usually easily separated from one another. The method you use depends upon the type of mixture you have.

5º AND 6º. Unit 5.Ecosystems

5º and 6º. Unit 5.Ecosystems

 



Each individual plant and animal could not exist by itself on planet Earth. All living organisms need millions of other living organisms to survive. How these organisms interact with the sun, soil, water, air and each other in a specific area is called an ecosystem. An ecosystem describes a specific area where the organisms work together as a unit. It could be any size from a tiny pool of water to hundreds of square miles of desert. Each ecosystem is different and each has established a balance over time that is important to every form of life within the ecosystem.

What makes up an ecosystem?

   An ecosystem is made up of biotic and abiotic components which include plants, animals and the environment in which they are found. The living or biotic components are made up of producers, consumers and decomposers. Some of the non-living or abiotic components include sunlight, temperature, water and soil.

DIFFERENT ECOSYSTEM AND HABITATS



Scientists discuss some general ecosystem types. They call them biomes. A biome is a large area on the Earth's surface that is defined by the types of animals and plants living there. A biome can be partially defined by the local climate patterns. You may also have more than one type of biome within a larger climate zone. Here is a short list of possible biomes.

- Tropical Rainforest (Think about Brazil)
- Tropical Savanna (Think about Africa)
- Desert (Think about the middle east)
- Mediterranean Woodland (Think about coniferous forests)
- Mid-latitude Grassland (Think about Oklahoma)
- Mid-latitude Deciduous Forest (Think about the east coast of North America)
- Tundra (Think about frozen plains of Alaska)
- Ice Caps (Think about the poles)

FOOF CHAINS AND WEBS



Food Chain

Food Chain

Read more at: http://www.ducksters.com/science/ecosystems/food_chain_and_web.php
This text is Copyright © Ducksters. Do not use without permission.
Every living plant and animal must have energy to survive. Plants rely on the soil, water, and the sun for energy. Animals rely on plants as well as other animals for energy. In an ecosystem, plants and animals all rely on each other to live. Scientists sometimes describe this dependence using a food chain or a food web. Food Chain A food chain describes how different organisms eat each other, starting out with a plant and ending with an animal. For example, you could write the food chain for a lion like this: grass ---> zebra ---> lion The lion eats the zebra, which eats the grass.

The Food Chain
Every living thing needs energy in order to live. Everytime animals do something (run, jump) they use energy to do so.

Animals get energy from the food they eat, and all living things get energy from food. Plants use sunlight, water and nutrients to get energy (in a process called photosynthesis). Energy is necessary for living beings to grow.
A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals.
