Get ready to explore thermal insulators and conductors in this exciting KS2 Science quiz, all about controlling heat!
Ever worn thermal underwear to stay warm in winter? It's like magic! Thermal underwear is a great insulator, meaning it keeps heat in. Insulators control heat to keep things hot or cold. Now, conductors are different - they let heat pass through easily. Imagine metal radiators – they warm rooms super fast because metal is a top-notch heat conductor. Take the quiz and become a heat control expert!

'Thermal' means to do with heat
|
Conductors and insulators are opposites to one another

Oven gloves protect our hands when we hold hot things
|
Metals conduct heat very well

Gold, copper and steel are all metals and would make very poor thermal insulators
|
Because it is an excellent thermal insulator, wooden handles will not burn your hands even when the pot is hot

Cold cannot transfer, or travel, from one material to another. Only heat can be transferred. Heat moves from warmer materials to cooler materials - when you go outside on a frosty day, heat is transferred from your warm face to the cold air!
|
Vacuum flasks are excellent thermal insulators - they can keep coffee piping hot. A material which can keep hot things hot can also keep cold things cold

Plastic would melt if it got too hot so it would be no good inside a cooker or on the bottom of a pan
|
Metal spoons can get very hot, especially when they've been left in the pot for a while!
