Graphs always make results look rubbish. Look at the slope on that! The accuracy is great though - serendipitously, these were the thermistors I picked for my project.
My bet is no, it isn't. I don't see how ice water could remain constant under non-ambient controlled temperatures (i.e. in a temperature controlled enclosure at 0C) because the ice is going to start melting straight away: at best, you can bring ambient water to a base temperature it will start to rise. What you could measure is (a) with one thermistor, ambient temperature; (b) with second thermistor the rate of temperature change over time. Plotting the ambient against temperature change by precise time you could probably calculate a rate of change, adjusted for fluctuating ambient. I'd expect this graph to look like a slewed U: steep left stroke, and shallow right stroke.
I don't know what it's like in Canada at the moment, but here in the UK it is around 500C ambient so this experiment isn't even feasible for us!!
Actually there might be something in that if you can tap a hole in the top put in the thermistor and seal it up so the flask can make a proper seal. You may want a different flask though: destroying a hot pink one can't be worth it!
