The real problem is that you teach this guy something which is MATHEMATICALLY right but not right if he want to understand the model behind his data. Do not teach him anything without you do not clarify that his model is not right for this case.

You can see later he will use this method for all of data what he must to analyse.

If he will work as CSI, he will use the polynomial fit for the body temperature cooling down - because he learned polynomial fit without any clarification.

Maybe he will design your medical stuffz when you will an old man - I hope, he will learn other models during thats years...

1.) Why do not teach him how he can decide which polynomial degree is sufficient to fit?
2.) What about your 6th degree model first derivative in t=0 and t=24? As I guess these values aren't same - so that is not a good solution.
