Physical Properties

Matter:Any solid,liquids or gas

Mass:Amount of matter in a objec.

Volume:The amount of spacean objects takes up.

Density:The amount of mass in a certain volume materials.

Physical Properties:A properties that can by observed without changing the identify of a substance

Physical Change:A change in size,shape and state without forming a new substance.

 Solutions:A mixture of one subtance dissolved to another so that the properties are the same throughout.

Chemical Change:A change in matter that produce a new substance with different properties from the original.

summery 3 food chain and food web

The producer are the one that makes his own food and comsumers are the one that hunt or absorb the food.The producers are the plant and protist and the consummers are the animals,bacteriaand fungi.The herbivore only eats plants and the carnivore eats meet.But is one type of animals that eat the two plants and meat.They are the omnivore.The food chain is the path of food from one organism to another and the food web is the overlapping food chains in the community.

summery 2 living things and their enviroment

The living and nonliving things are part of an the ecosystem. But they are two groups aboitic and biotic.The abiotic factors are the non living things examples :light,water,soil,temperature,minerals and air.And the biotic factors are the living things .EXAMPLES:plants,animals,fungi,protist,and bacteria.Some scientist study ecology to know how the aboitic and biotic factors live or how they interact in the inviroment.

summery1 energy resources

Is  two type of energy alternative energy and geothermal energy .All the time we use energy in the day an in the night but in the night we dont use to much energy but in day we use more.In others countries they use the biomass to make fuel that is an example of energy.Brazil is the number one county that use biomass to make fuel . That fuel named gashol that they make with corn.

earth changing crust

Fault: a crack in the crust, whose sides show evidence of motion.

2.Geologist: a scientist who studies Earth's surface.

3.Magma: hot, molten rock deep below Earth's surface.

4.Lava: magma that reaches Earth's surface.

5.Weathering: the breaking down of rock into smaller pieces.

6.Erosion: the picking up and carrying away of pieces of rock.

7.Deposition: the dropping off of bits of eroded rock.

8.Meteorite: a chunk of rock from space that strikes a surface ( such as Earth or the Moon ).

earth and its neighboors

Solar system: the sun and the objects that are traveling around it.

2.Planet: any of the eight large bodies that travel around the Sun and shine by reflecting it light.

3.Gravity: a force of attraction, or pull, between any object and any other object around it.

4.Inertia: the tendency of a moving object to keep moving in a straight line.

5.Lithosphere:the hard, outer layer of Earth, about 100 kilometers thick.

6.Crust: the rocky surface that makes up the top of the lithosphere.

7.Resource: any material that helps support life on Earth.

8.Hydrosphere: Earth's water.

matter and energy

Kinetic energy: the energy of a moving object.

2.Potential energy: energy stored in an object or material.

3.Conduction: Movement of energy from a hot  object that comes into contact with a cooler object; the material remains in place.

4.Convenction: movement of energy by the flow of matter from place to place.

5.Radiation: movement of energy in the form of waves that can travel through empty space.

6.Wet cell battery: a battery containing liquid solution that produces the electricity current.

7.Dry cell batery: a battery that uses "dry chemicals" to produce an electric current.
