I have taught kindergarten, primary, secondary and sixth form, and the Primary school project is king! Just picked up my son's overflowing end of year sack of work and the highlights of the year were, egg's and chicks, the Amazon (river!), and Shackleton's journey. They have all made their mark on an impressionable mind and are the kind of things that you remember forever.
What can technology bring to this feast of knowledge? Well for one the 'too spooky', phonics / cursive writing app can be re-skinned as a dinosaur adventure for reception projects . ;)
