In this paper, we asked college students who were aiming to become science teachers to take time-lapse videos of clouds and analyzed whether they could capture the diversity of cloud flows from these videos. The results showed that 96.2% of the videos showed cloud flows, and 28.3% of them captured the diversity of cloud flows at different altitudes. The participants were asked to analyze what they could find in their own videos and the videos of all the participants in a step-by-step manner. The results showed that less than 20% of the participants were able to find that the direction and speed of cloud flow varied with altitude in their own videos, but 30–50% of them were able to find these differences when they viewed the videos of all the participants. This suggests that it is effective to analyze as many cases as possible in order to find and appreciate the diversity of cloud motion. Finally, 40.7% of the students were able to convey that atmospheric flow can vary at different altitudes, based on the discussion of cloud flow. The students' self-evaluations after the practice lesson were also positive, suggesting that analyzing time-lapse videos of clouds is effective, especially in finding that the direction of cloud flow varies with altitude.
