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

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.
