Int Task 3
Design plan (A) * Problem Statement- Which liquid freezes faster hot water (212 degrees) or cold water (35 degrees)?
* Relevance to testable question- My experiment is relevant to my hypothesis because I directly comparing which freezes faster the container of hot war or the container of cold water.
* Literature Review- I’ve read many post on the internet arguing which freezes fastest, In particular there have been two specific ones that have caught my eye. I found this interesting video over a similar science experiment (Link: http://www.youtube.com/watch?v=xOVZV6DxaRs).In this experiment it is not done in a freezer it is actually done outside on a cold day (-15 degrees.) What the experiments consists of is using two cups of water one is filled with cold water (35 degrees) and the other cup of water is filled with hot water (212 degrees.) The way he goes about conducting his experiment is simply stepping out and tossing the two glasses in the air the cold water falls to the ground still wet and on the other hand when the hot water falls to the ground it falls solid as ice thus proving that hot water freezes fastest. In my opinion this experiment isn’t as controlled as it should be there are many uncontrolled variables that are not even mention, but he does repeat the experiment two separate times leaving the viewer with some sense of validness. I found another experiment online (link: http://www.fizzicseducation.com.au/experiments/Kitchen%20Chemistry/freezing%20hot%20water.html ) it is a very short and not very detailed. The supplies listed are very concise but the directions are not. The afterward explanation of the experiment solely relies on the Mpemba effect but yet it doesn’t really conclude the experiment. I don’t not like that it leaves a lot of open questions but it does support my experiment. * Experimental design- * A. The design of my experiment is very basic. I will use identical plastic clear cups exact same make and
