I visited my school!

Three days after I arrived I registered for the "Scientists in Schools" project, in which a Scientist (that would be me, ha!) partners up with a teacher from a school and they share and do interesting stuff for the benefit of the kids at the school. I thought it was quite a cool idea and I think that I would have appreciated it when i was young (not so sure about now though) ... After three months and a police database check (i kid you not) I was finally approved and got a partnership with a MATHS (!!) prof in some secondary school (can't say the name Google!)

It's gonna be a bit difficult at first because while the math level we are talking about (level 10) is very very very low (they do quadratics! in year 10! ) both the teacher and i are total noobs at this.

Nonetheless, we were thinking about how to make students see that the maths they are learning is applied everywhere in real life. So far, examples we could come up with were: a) gps triangularization and b) angry birds (because of the trajectory and hence the quadratics)

So i ask you, esteemed council, what other examples of quadratics (ax^2 + bx + c = 0) or simple statistics in real life would you have?
