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...
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...
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...
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...
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...
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...
rogerfrost.com is a compendium of ideas for using technology to find answers to sciencey questions. Since 1995 it has provided ideas to school science teachers. Since 2020 we’ve focussed on questions around the home with a new home automation section. So today we look at ways to measure and monitorĀ around the house.
You will find everything here tagged and indexed by topic or technology.
Roger Frost was a writer from 1988 and this web includes many of his articles for magazines and newspapers. They tell how the early Internet developed; how real scientists work and how real people, like you might use technology at home or school.
