Welcome to our redesigned, fully indexed collection of experiments using data logging technology. Now incorporating the scientists at work careers podcasts.
The First World War, that began in 1914, put chemists to work. Their chemicals could harm as well as heal … but on balance the outcome was … horrific. As the author of two...

Here are pictures of labs, data loggers, sensors and experiments from the 1990’s to the 2000’s. You’ll see different solutions to computers in a lab and for example, different colorimeters and different ways to...
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...
Batteries are a handy source of power. Just think of all the things that use them – calculators, cassette players, even computers will run on batteries. You’ll know that there are different kinds of...
Radioactive materials decay, or lose their radioactivity, in a predictable way. If you have a fast decaying source, such as Protactinium with a half life of just 72 seconds, you can take a series...
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...
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...
Measuring the appearance of cloudy sulfur when we mix acid and sodium thiosulfate is a popular science teaching activity. We can change the temperature or concentration of the reagents, and see whether the mixture...
A lot of people use science at work and more so here in Cambridge, England. We started interviewing them for our radio show from 2011 up until 2014 and here they are. While the interviewers...
We’ve recorded dozens of scientists and entrepreneurs talking about what their work involves. We hear from experts in Cambridge, England as they talk about their inventions, discoveries and interests. We shout to twitter @105science.
A Cambridge project seeks to improve farming practices in Africa by sharing advances in biotechnology. They’re called Biosciences for Farming in Africa (www.b4fa.org). Chris Creese meets one of their founders Dr David Bennett. There’s a ‘demonstration...

Sensors to measure heat and temperature These sensors are available in all flavours to suit different applications. You should be able to decide on the type that suits whole class use and have any...
Perhaps someone once asked, who is Roger Frost? He’s a writer who used to collect ideas to teach science which this web aims to record. Over twenty years, Roger Frost ran ICT and science training...
Roger Frost writes: At the time the idea to measure acceleration (and GPS position) in a country park on a Segway was the closest we scientists ever got to being ‘cool’! Of course it...
rogerfrost.com is a compendium of ideas for teachers using technology in school. It shows how to use IT to find answers to science questions.
Now retired, Roger Frost was a copywriter and journalist so you’ll stumble on articles from wayback when. Please use anything or credit this. And do drop us a helpful line sometime.
