Natalie and I were nosing around a science fair website tonight looking for inspiration for a science project (found it!). It was interesting to see that the two projects we looked at were both concerned with cost effectiveness or unit cost. One tested the lifespan of batteries, and hypothesized that more expensive batteries would last longer (though he didn't dig down to unit cost). The other tested the effectiveness of tile cleaners, and did make it through to the unit. It was pretty interesting that both the students were concerned, at such a tender age, with brand and value. They didn't try to dig in and figure out what physical properties of the things made them better, they just correlated them with wallet impact.
