Cranbrook Children Visit Bancroft's Science Fair! During Science Week, 8 budding scientists from Year 5 and 6 were lucky enough to attend Bancroft’s Science Fair. It was phenomenal! The Fair had 4 different sessions: biology, physics, chemistry and the fair exhibition itself. The children made and launched their own own rockets, experimented with slime, bubbles, dry ice and the colour spectrum, they were also lucky enough to observe various chemical reactions in a science lab!
