rogerfrost.com is a compendium of ideas for using technology with sciencey questions in mind. Started in 1995 to offer ideas to school science teachers, Roger Frost expanded the coverage to home automation, gadgets and sensors to measure, or understand, what’s going on around him.
To find things the search box, the menu and the keywords work perfectly (and we’re totally free as in advert free).
Roger Frost has been writing about technology since 1988 and this web includes articles; radio interviews with scientists and tutorials to use technology at home and the classroom.
