Toy 3 - Fish To Go Reflection

In retrospect I feel like this toy could be more successful if it were simplified. I think that the temperature gage is important, I think understanding temperature can be a difficult topic because it is hard to see precision. As children we can generally identify cold to cool to room temperature to warm to hot, but no more specific than that. I think that this toy would be better at teaching temperature rather energy conversion. I'm not exactly sure how this piece would be built, especially in terms of safety and containing the liquid.
