A teacher, Jocelyn, introduced the topic of heat energy to her class by letting them watch three different videos.
The first was of hot lava being poured on ice, the second was of lava entering the Pacific Ocean, and the third was a video of a melting ice cube. She then posed four to five guiding inquiry questions on KF for each of the three videos, for students to think about and research on (Fig. 1). For instance, Figure 2 shows the four questions she posed regarding the video of lava entering the Pacific Ocean.
All the inquiry questions were in fact intended to be a lead in to the concept of heat energy. By introducing unknown phenomena to her students as a trigger activity, Jocelyn encouraged them to explore, inquire, and come up with reasons to explain what they saw in the videos.
