latent heat – salty ice

When it is icy they put salt onto the roads to melt the ice. What the salt does is to depress, or reduce, the freezing point of water. The result is that the ice...

heat conduction through a window

Get two temperature sensors to measure the temperature inside and outside a window. You may find that over a long period of time it is best to record your data remotely. This means that...

heat conduction

You can use a temperature sensor to study the conduction of heat through materials. Two temperature sensors allow you to compare different materials at the same time. In this example, you heat strips of...

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...

heating ice

You would think that when you heat up ice that it gets warmer bit by bit. And maybe that the more you heat it the hotter it gets. Well it’s not like that. We...

day and night light & temperature

What time does it get light in the morning? When does it get dark? Is the central heating working? I just had to know, so I took my data logging equipment and started to...

add the milk to tea now or later?

The dilemma is this: the telephone range as I was making tea. Should I add the milk now or 5 minutes later, after I took the call? One way of answering this is to...

compare insulated drink beakers

An investigation with insulated and un-insulated beakers – reloaded “I bought a metal mug to carry my coffee for my daily trip to the train station. But twenty minutes down the road, I wasn’t...

scientist 49: the building scientist – heat pumps and an eco-home (2012)
