Roger Frost's Technology for teaching science Blog

scientist 69: the science author – Michael Freemantle says WW1 was the chemists war (2014)

Scroll down for the recording. Additional notes by Roger Frost – with thanks to Dr Freemantle.  The First World War, that began in 1914, put chemists to work. Their chemicals could harm as well as...

museum of data logging

From the 1990’s to the 2000’s here are pictures of a collection of labs, data loggers, sensors and experiments. You’ll see different solutions to labs, different colorimeters and different ways to measure acceleration. Yes,...

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...

types of battery

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 half-life

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...

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...

measuring visible change in liquids

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...

the Science Show on Cambridge 105 radio featuring scientist at work

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. 

who is Roger Frost?

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...
