I am particularly interested in letting each child have a Eureka surprise moment of their own in any field which affects their confidence. i.e It need not be learning something in a laboratory or classroom but it must be personal and develop the appreciation of science method.Is "The science fair" the only way of achieving this in the USA? I started as a CBA( Chemical Bond Approach - American scheme) and spent most of my teaching as a Nuffield (UK Foundation)Teacher. Age range taught 11-18(scholarship) ;comprehensive( state) grammar(state) and private (None state) plus private tuition.
