“Using Whizz pop bang school resources has enabled investigations to be an integral part of my science planning. I now have investigations and experiments throughout my planning rather than just at the end. The lessons are easy to resource, and the pack has everything I need to teach the lesson, so it saves me time as well!” Louise Hampson, Year 3 teacher
