Question with the "Mpemba Effect' experiment

[Bananadifa]

I have a quick question about the Mpemba effect experiment, which investigates whether hot water can freeze faster than cold water. One of the comments made past experiments was to keep the freezer shut as much as possible. How would I do this if I am going to check the temperature at every time interval? (5 minutes.)
Also, if I get a result that contradicts my hypothesis that hot water WILL freeze faster, should I change my variable or conditions? Thanks.

Hello, to help try to keep the freezer shut as much as possible, do things such as not open the door all the way when you take your measurements and also try to take your measurements as fast as possible while still maintaining a high degree of accuracy. Also, if your experiment shows results which are contradictory to your hypothesis, do not go back and change your experiment. A hypothesis is an educated guess, not a definite answer, so there is all ways the possibility that your experiment will contradict what you stated previously in your hypothesis.

Another approach to take would be to use an electronic thermometer with a remote temperature probe so you don't have to open the freezer at all.

One thing to note: the Mpemba Effect is notoriously difficult to reproduce, so don't be discouraged if it takes several tries with slightly varied conditions, or even never succeeds at all. Science is especially useful when it shows negative results. Just keep close track of your conditions and record them carefully, and you'll have a good experiment whether you get the effect to happen or not.
