Both experimental sciences and mathematics are essential subjects that are often associated with a lack of interest and motivation among students. That is why we have put our focus on them and in this work we propose new resources to work on them in an enjoyable, fun and motivating way while still giving them the importance they deserve. That is why we propose a methodological proposal to be developed in kindergarten and primary education. In order to know the effectiveness of this type of resources, an evaluation is carried out before, during and after the experience using different evaluation instruments (interviews, murals and rubrics), in order to know if the results are satisfactory or not and if it is interesting to consider the continuity of this type of projects or not.
