  • ok

  • Wow

  • Slides !Hey Guys should I go on this slide?

  • Yes

  • Zoooooooooom,Ouch ,it is very hot

  • It is burning

  • I don;t know what's wrong with it?

  • Should I that one?

  • Hmmm

  • Zooooooooom

  • Wow ! You are having Fun. Yes

  • But something is wrong with this slide! This is very hot.

  • Oh this slide is made of metal.

  • It is a good conductor of heat.It takes heat from the sun and

  • transfers the heat to anyone who touches it.

  • But sun rays are falling on this slide too but it does not feel hot

  • Look closely,it is made of different material.

  • It is called plastic.It does not absorb or transfer heat..

  • Ohh.So few materials absorb and transfer heat

  • But others don't .Yes ,you're right.

  • Few materials like metals

  • let heat go through,these are called conductors.

  • so this slide is made of metal,it lets the heat go through it.

  • so it is conductor.

  • Yes metals are good conductors of heat.And this slide is made of plastic

  • it does not let the heat pass through it.

  • it is not a conductor .Yes ! Some materials don't allow the heat to pass through them

  • These materials are known as insulators.

  • Hmmm,conductors and insulators

  • Guys ! Do you understand it? Can you show me more examples?

  • Let's check those benches. Touch it carefully.

  • Ouch! It is hot.

  • Can you what material it is?Oh this material should be metal!

  • That is why it is letting heat pass through it.It is a conductor of heat. .

  • Hmm,you're right. This bench is made of metal and metals are good conductors of heat.

  • Ok.Now let's go to the other type of

  • bench.I am not going to touch it, i don't want my hand to be burnt.

  • Ok ok.Let me touch it.

  • See nothing happened.

  • You can also try.

  • Hmm,it is not hot.The material of this bench seems to be made up of some insulator.

  • Yes ,this bench is made up of wood.

  • And wood is an insulator.It does not the heat go through it.

  • So guys! now we know all about insulators and conductors.

  • Hold on guys,there is something more. Now what is that?

  • There are electrical conductors and electrical insulators also

  • Electrical conductors and electrical insulators !

  • What are those?To learn about those,we need to go home.

  • Wow ! Is this an electric circuit?

  • Yeah,but it is incomplete. Oh ,that is why the bulb is not lighting up!

  • For that ,we need to complete the circuit.

  • You said it right.You are a genius boy.

  • Let's try to complete the circuit with the things lying here.

  • sheila is a peeper strong this company does suck it

  • with the help of it okay let's try all

  • blog does not night up that meet

  • a paper straw does not lead the electric current boss

  • through it beat but does not let car and go through it

  • it is an electric bill insulated

  • all nah I get it the mighty his dad do not

  • I allow electricity to 5 through damn are known as electrical insulators

  • me right let's try this food

  • while just bored lets the climbing

  • passed through it that meets the Bud Light down

  • yeah and the school is made of mickey and mentors up good conduct is a

  • electricity all maintains a good conductors of heat

  • I sweat as electricity yes next ride isn't

  • wouldn't chapstick

  • mom does not like done the phone in the Guardian

  • that book is any tornado of heat and now the seabed

  • electric it to me also you got it right

  • said now you know about insulated and conducted

  • can you tell me something about this awhile

  • why is it good nasty nafta

  • good electrical insulate back if I needed used to cover Mickey DS

  • next Rd electricity parts coming that surrounds by and effect in my

  • chicken infuriate stop him from getting

  • lot to the shock Olukemi

  • I knew all all the electricity supply

  • in our home got still be is kinda violence

  • said now do you know the difference between NCAA 10

  • drop dead yet but now it does I does my teen years

  • naked cut it all he'd 52 again

  • and City does I'd almost bag don't black guy can't

  • of heat to get to game camping

  • have a question by some ideas to conduct does but

  • a nice I to lead us click

  • question forget we need to look in three teams in a different connected

  • I know all anybody does not mean Obama activist

  • any yet passing UPS in this sector dont

  • behind Outback your piece yeah having fun it's

  • you give some make stop by me but to make sure enough to move from one

  • to comment but does does

  • Syria what is the difference between them political

  • him back I'm a charm our baby news he bound to the nuclear

  • beacon roofing better new division

  • but until eight electron can't thing

  • so many delete FB seeking nuclear

  • noted sure get got does

  • European is fixed like talk scandal

  • luv FB you've gone 3

  • John I'm movement John you've got going

  • on electricity that is why

  • playing can chill it through the conductor nice he

  • you look at the John can't move unbearable

  • to be want to buy looking to get back bends because factual

  • bookkeeping them with me keep cool in school

  • sleep time start moving or third trucks were

  • commented to me to all just how

  • he telling kind last conduct does

  • scanning 3 on rookie popular time

  • in contempt of Congress further new

  • up luck current doctor an ancient nato's

  • it turns out very tacky pack Saudi do not make cutting

  • to past so guys to db9 about conductors and insulators

  • you can't invite other units out so I meet me gene is Jack

  • and peace me space like biting

  • thank you about

ok
