Abstract
Evolution is considered the unifying concept in biology and is also a key theory underlying many areas of human knowledge. Teaching evolution from as early as kindergarten allows children to better understand concepts related with the biological world and prevents the development of negative feelings and misconceptions about the theory of evolution. However, evolution is absent from most of the educational curricula in the early school grades, even though some of its central concepts are common contents in the curricula of these initial years. In the present paper we present a set of activities that can be performed with elementary school students to explore and understand evolution and its impact on biological diversity, while promoting critical thinking and scientific literacy. These activities explore concepts of intra-specific diversity, genealogy and inheritance, natural selection, genetic drift, and systematics, using contexts that are familiar to students, and were articulated with the Portuguese official curriculum. Similar contents are present in elementary school curricula of other countries, namely Brazil, United Kingdom, France, United States of America, Canada, or Mozambique, and therefore the same activities can potentially be used in many different countries. Regardless of the complexity of the theory behind these concepts, our experience revealed that using these activities children were able to understand basic evolutionary mechanisms and to apply this knowledge in real case scenarios.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
