insulation

You can use a temperature sensor to study the insulating properties of materials. Two temperature sensors allow you to compare different materials at the same time. In this example two beakers of hot water...

freezing a bun or bread roll

We scientists do the strangest of things. We wanted to see the temperature changes when you freeze and thaw things. So we took a ‘bun’ (a bread roll), placed temperature sensors in and around...

a cooling curve

I expect that when something cools, it will get cooler in a plodding kind of way. That’s true, but when something changes state, the cooling is not so steady.The graph below shows how liquid...

hack for test tube holders – like no other

From Roger Frost’s austerity lab tips, when you run training days in hotels, one improvises, as this tip shows: This IKEA tea towel clip gained an unusual second life as boiling tube holder – although...
