Abstract
Evolutionary evidence is important scientific background for appreciating the theory of evolution. We describe a STEAM-based lesson plan that uses paleontological drawings and a modern evolutionary database to explore and understand fossil, morphological, and molecular evidence. Together, with a focus on arthropods and the Cambrian explosion, students experience a heuristic process common in scientific reasoning, guiding them toward practices that synthesize knowledge and invite questioning in the life sciences.
摘要
进化证据是理解进化论的重要科学背景。我们描述了一个基于STEAM的教案，该教案使用古生物学绘图和现代进化数据库来探索和理解化石、形态学和分子证据。以节肢动物和寒武纪大爆发为重点，学生们共同体验科学推理中常见的启发式过程，引导他们进行综合知识并引发对生命科学质疑的实践。
