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
