This video can be used as a way to present the topic: Hydrocarbons – comparison of alkanes, alkenes & alkynes, then when it is necessary teacher can explain new words, or prepare a list of new words before watching. There can be a given list of questions for students. It will be a way of checking if students understand the video. So students are split into small groups and they can work together to find out the answers. In these groups students will have time to speak out their ideas. They can discuss if they are right or wrong, so it will be a good way that everyone will be able to say something. After that, a leader of each group can present their answers. Each group can compare the answers. Then a teacher can summarise the team work, correct or explain questions. In the end, a teacher can ask students to write a short review of the video.
