Sanjay's class was studying the water cycle. Their teacher asked them: "Where in the room will the most evaporation take place?" In small groups the children collected the following materials: ~zip lock bag ~soil ~water in a spray bottle ~tape Each group added soil to fill the bottom 1/4 of the bag. Next they sprayed the soil with water. They sealed the bags and taped them in a sunny window. The next day, at 11:00 am, the students checked their bags. Here is a photograph of one of the bags; the student models all looked similar. Is this a fair test? Explain. A) No. The students did know if any evaporation took place. B) Yes. All of the students followed the same steps when setting up their model. C) No. The students should tape bags in different places to get different temperatures. D) Yes. The students could see that the water in the soil evaporated and then condensed on the bag.
