Cross-curricular series centred on sustainability and climate change, with hands-on projects linking science and design and technology. What are the problems and challenges we face around the world when it comes to farming and growing crops? How can we farm without habitat destruction and damage to food chains? Interactive ‘Solve It!’ design challenges give readers the information they need to develop sustainable solutions to the problems discussed, and step-by-step ‘Test It!’ activities encourage them to explore putting principles into practice.
