You can think <br /> of theta as the 'building; blocks of matter"'They are year <br /> smaiIII, but:they make up everything in the universe, They <br /> are like tiny Legos than you, can use to make all swts of <br /> tl ngs� Castles!Cars' Towers! P4rnimak! From small building <br /> blacks, you can make larger, complicated things. But your <br /> can.always break those things down to atoms. <br /> PARTICUES: Atoms are composed of three evert smaller, parts called particles. <br /> Protons are posili4ely charged particles, neutrons have no charge„ and electrrons <br /> carat a, negative charge. The protans and neu are lied together in the <br /> center of an atom in a tight huddle called a nudeu�'The etectrwis are in content. <br /> motion, a round the nuc euso Electrons are very small compared to pr ts: and <br /> neutrons.You can think of eNectrts like bu le bees buzzing around a.huddle of <br /> penguins(the protons,and neutrons). <br /> OPPOS=ATTRACT. Positive and negafive,chaiVes <br /> -•�- Attract are attracted to each other and want to Come <br /> together. Similar changes don't -want ti come <br /> togLeth t tfwey want to std apart .or. repel each <br /> : w others The negate electrons are a , to the <br /> ".�• <br /> positive nuc eus. and so they Usually stay. ,tear their <br /> Protorls. <br /> ELECTRONS MOVE AND FLOW: When electrons,get r ll'y excited, they can leave <br /> their atoms and flow off In search of a posiOve charge to connect with, Electrons <br /> f1crA, really viell through metal. Tbae's why metal things are conductors of <br /> electricity. S is also a .good conductorr. Electrons don`�iv -w l through <br /> things like r bl r� wood, and pl: Those are i nsulatooss. <br /> M 1" � E ONS= C ''o Electrons in motion, have en,errrgy,. In order <br /> to use this energy to power electni cal appliances, vie need to set up ciemits with <br /> an electric cu, Electric currents: affe similar to the fimving votes in a river <br /> current which travels in one direction, We can create an electric cira a. with a <br /> constant flow of electrons. <br /> — - <br /> Page 17 of 21 <br />
