The experience of the Science Camps in five countries, in particular the contribution of the experts
        who made presentations and engaged in a dialogue with participants allowed us to collect relevant
        information about the four science topics addressed . This chapter contains the main questions
                                                                 29
        students asked after watching the videos, as well as the answers the experts provided. We believe
        this can be useful for clarifying participants’ doubts during science dissemination events. Additionally,
        we collected a list of trustworthy online resources for the four topics.

        What  are climate models?  How  are they
        built?                                                  There are several models and they coincide at
