The teacher introduces the topic (Refraction of Light - Why does a pencil look bent in water?) and asks students to come up with their own suggestions and has students check their answers by watching the video. The video may make an interesting introduction to the topic that can raise students’ curiosity. Then s/he brainstorms key words/concepts from the video. S/he invites students to watch the video again and take notes while they watch the video. S/he has to provide enough structure and support around this task (a graphic organizer like a response sheet – true/false; questions; ordering statements). Then s/he asks students to write a brief summary and present it to their peers. Students can do the experiment and complete their knowledge by doing some online research on the topic and share their findings with the class (https://www.youtube.com/watch?v=zarxpu43-ls/ https://www.youtube.com/watch?v=NLmpNM0sgYk).
