    In this evolution by natural selection lab, students start by answering questions on how mice's habitat affects the survival rate of different fur colors of mice. The students simulate the mice using a fork or spoon and a cup and try to eat pom-poms. The pom-poms are different colors, and they reside in different color habitats. Students learn how other evolutionary adaptations contribute to differences in survival and reproductive rates, allowing students to see changing allele frequencies in their modeled population.

    Students role dice and chart how a pretend worm population reproduces through many generations. This activity is easy to perform and lets students visually see how an allele frequency appears to occur randomly. 5 colored pencils and dice are required for each group of students.

    This comic follows the efforts of a male cricket as he tries to attract a mate, and in the process, debunks common myths about what it means to be evolutionarily "fit."
