Then we have a lab, but today Mr. Doyle feels not good, because we always talk and he think we are so rude. So he feel not very good today. And speak very loudly in the class. Then we have a lab, We use water, cooking oil and alcohol. First, Mr. Doyle give us two thermometers, one is use to measure room temperature, one is use to measure substances evaporation and then how many temperature does it change.107 We use napkin to cover thermometer. And then we use dropper to wet napkin, and when teacher says start. Then we use book to make wind let it evaporation faster. Then we get 22. And the room temperature is 22.5. So it only change 0.5. And we do the same on cooking oil. We also get 22, and it also only change 0.5. And we don't believe it and Mr. Doyle also do not believe that but we can not do it again. So we continue and we get 19 when alcohol evaporation. And it change 9.5.
It's so funny lab.
