After thought
It doesn't often happen but sometimes what we do in physics ties in nicely with what they do in maths, as a result my students seem to know all about parabolas. Today they even had two consecutive tests where they had to use the quadratic formula, how lucky is that! In maths they have to relate the graph with the equation in physics they should be able to relate the motion with the graph and the equation. I've been using the phET equation grapher to plot displacement time graphs for different "throwing ball" situations. I this way they get the idea that the shape of the graph is basically the same its just the point that we start in space and time is different. I thought that a better way to make this point would be to move the axis around instead of the graph. I did this on the SMARTboard by simply dragging the axis around a parabola that I copied from somewhere else.
To be honest I didn't actually do this in class I thought of it afterwards when I was walking home. If I remember next year I'll use it.
