Part of a fab series of 6(5) Science Topic Workbooks aimed at 10-11 year olds, this book covers Micro Organisms and Reversible Changes. 6B and 6D are two short units in one book, covering everything kids need to know about germs and reactions for Year 6. It's got loads of questions, and a fantastic A3 "banishing micro-organisms" poster. It also includes pull-out answers. And it's perfectly matched to the National Curriculum, so it's ideal for following the school Scheme of Work or using at home as helpful practice material.
