Abstract [sv]

Med hjälp av en handhållen värmekamera kan elever se hur värme leds genom metall, och hur andra material som trä eller plast isolerar. På samma sätt kan de se värmeutvecklingen då ett suddgummi dras mot ett bord eller ett bouleklot slår i marken. Den här typen av fenomen har vi ofta sopat under mattan i undervisningen, eller förklarat i termer av ”värmeförluster”, utan att kunna ge egentliga belägg. Med andra ord, värmekameror gör det möjligt för elever att se fenomen som annars är osynliga.
