An experiment of a poorly described hypothesis that has had many inconsistent results due to the huge number of confounding variables is about the worst possible choice for an educational experience for a student.
On the contrary, I think it's an excellent choice. It will teach:
1. The importance of having a well defined hypothesis in the first place.
2. The importance of good experimental design.
3. The reason for doing experimentation in the first place. Sometimes you get an unexpected result that goes against you original hypothesis (poorly defined or not)
4. The need for follow-up studies to better understand the nature of the phenomenon.
5. That the real world is complex with many variables.
You are right, the Mpemba effect is messy, poorly understood, of variable reproducibility and with a range of differing theoretical explanations. This is what most scientific experimentation is like in the real world!
I'd rather my son learn this now and have fun doing so!
