This series shows children how to carry out basic experiments, predict results and assess outcomes. The comments made by the characters inspire conversations and observational exercises. Rich in specialised vocabulary, these books encourage budding scientists to record their findings and include examples of purposeful writing. Many of the scenes could be used as a basis for activities that improve fine motor skills. The characters recognise when their ideas don't work; they model a growth mindset by laughing off their mistakes and learning from them. The books also provide examples of critical thinking and tool-use.
