first quarter

IN THIS FIRST QUARTER WE ENJOY THE SCIENCE CLASS. WE MADE PROJECTS, SPEECH, AND ALSO WE ENJOY TO MUCH THE LABORATORIES.

Tempeture and heat

Vocabulary #4

the energy of  any moving object is called KINETIC ENERGY

tthe energy stored in an object is called POTENCIAL ENERGY

is a meassure of the average kinetic energy of the molecule in the material is TEMPETURE

the energy that flows between objects that have different tempeture iss called HEAT

the transfer of energy by electromagnetic waves is called RADIATION

the spread of molecular motion between areas of iffernt tempetures that are in contact is called CONDUCTION

the transfer ofenergy by the flow of liquid or a gas is CONVECTION

prevents the heat from flowing in or out of a material INSULATION

Chemical change

Vocabulary# 3

a chemicl ombination of two or more element is COMPOUND

a link that atom or atomic-sized particle can form is CHEMICAL BOND

the using of letters and number to show how much of each element is in a substance is CHEMICAL FORMULA

is an  electrically charged particle with unequal number of protons ad electrons is ION

a goup of bonded  atoms that act like an single partile is called MOLECULE

describing how a substance change chemically with other substance is called CHMICAL PROPERTY

chemical reations that gi off heat are said to be EXOTHERMIC

chemical reaction that absorb heat is ENDOTHERMIC

Elements and Atom

Vocabulary #1
Pure subtances tht cannot been broken down further into anything simpler ELEMENT


Is the smalest particle of n element ATOM

An atom´s dense center NUCLEUS

A possitively charged particle inside an atom´s nucleus PROTON

A particle with no charge inside is NEUTRON

A particle with negative charge inside is ELECTRON

The number of protons in an atom is ATOMIC NUMBER

Any group of elements that conduct heat and elctricity METAL





Physical properties of matter

Vocabulary #1

anything that has massand volumeis called MATTER


Any solid liquid or gas is MATTER                                                    






Is the amount of  ofmatterin a object DENSITY

The amount of space an object takes up is VOLUME

summary 3

Food chain is the energy`s continues is like a cycle but at final are the decomposer. Food web is eating the consumer to the producer. Food chain and Food web are not the same you can though that but is not the same. We are consumers Plant are producer . we are omnivorous and grasshoper are herbibors.

summary 2

Living things and their enviroment , we need abiotics things to live : for example , the flower - the soil and soil is nonlivinthing , Animals - the water , water also is an nonlivingt thing. Enviroment is where an biotic and abiotic interact each other. the ecology is the study of how living things interact in their enviroment. population is where a organism of the same specie live at the same time. Community is the population living in an area. Habitat is where someone live. And NICHE is the role in your enviroment.

summury 1

Energy resource is Althernative energy, Geothermal energy, and Biomass .
In Brasil don`t use fossilfues, they use biomass from the corn. althernative energy is : wind energy, water, solar and geothermal energy. Geothermal energy is the Earth`s internal energy.
