Here we can watch some students who wanted to participate in the edition of the video. There is a part in Spanish because of the transversal approach to the topic. It was not in our planning to include an improvised explanation (Spanish) from a six grader to younger students in a workshop we had (once a week we mix 5th and 6th graders in the afternoons). That's what that student understood from the greenhouse gases and using his own words he did it great, so that we were forced to shoot a video!
