Don’t forget, educators can visit Granta’s Teaching Resources Website to browse, search for, and download relevant resources for those teaching materials across science, design, and engineering courses.
Thomas Friedman has stated that ‘the world is flat’. He’s not recanting modern scientific discoveries, but he is highlighting that everything, everywhere, is somehow connected and that what happens at some part of the world can have drastic implications in other parts. It’s another way of saying that we live in a globalized world, that we eat, drink, and perform our daily activities using products that sometimes come from such remote places that we don’t even know they exist – take the horse-meat scandal as a recent example!

Few products get a worse press than plastic shopping bags. They are distributed free, and in vast numbers. They are made from oil. They don’t degrade. They litter the country side, snaring water-birds and choking turtles. Add your own gripe.
Paper bags are made from natural materials, and they bio-degrade. Surely it’s better to use paper? And come to think of it, why not bags made out of jute – it’s a renewable resource – and use them over and over? That must be the best of all? Continue reading
Regular readers of this blog will know all about gold. Now I’m going to talk about why green is the new gold, focusing on why companies are trying to deliver greener products, and providing some tips for how to do it.

Companies often find that trying to lower the environmental impacts of their products also leads to lower manufacturing costs, through the reduction of materials, energy and waste. For designers, thinking about sustainability issues can offer a new and fresh perspective on the products they develop—helping them to spot opportunities for waste and cost reduction. Smiths Detection provide a good example of this. When redesigning an existing product with sustainable design principles in mind they were able to save nearly $160,000 per year in manufacturing costs (download the case study in PDF format here).

As the 2012 Olympics open in London this week, athletic achievements, and gold medals in particular, are drawing everyone’s attention. At the original Olympics in ancient Greece, the winner simply received an olive wreath: when the games first restarted in 1894, winners received a trophy. For most of the recent Olympic history, however, the crowning glory of any athletic career has been the Olympic Gold Medal. But behind the excitement of sporting prowess, we wanted to know more about the gold in the medals themselves.
