  • Modeling Food Webs in Darién, Panama

    Modeling Food Webs in Darién, Panama

    Card Activities

    In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.

  • Modeling Trophic Cascades

    Modeling Trophic Cascades

    Card Activities

    In this activity, students model trophic cascades, which are also explored in a variety of related resources, using cards of animal and plant species from seven different habitats. It is designed to illustrate the species relationships in a food chain and the effect of predators on the trophic levels below.

  • Creating Chains and Webs to Model Ecological Relationships

    Creating Chains and Webs to Model Ecological Relationships

    Card Activities

    This hands-on activity allows students to build model food webs and then evaluate how ecological disturbances affect each trophic level.

  • Using DNA to Explore Lizard Phylogeny

    Using DNA to Explore Lizard Phylogeny

    Card Activities

    In this activity, students explore the phenomenon of convergent evolution presented in the short film The Origin of Species: Lizards in an Evolutionary Tree. They build and interpret phylogenetic trees to infer how certain adaptations evolved among the Anole lizard populations of the Caribbean.

  • Biodiversity and Evolutionary Trees

    Biodiversity and Evolutionary Trees

    Card Activities

    These two activities support the Click & Learn Sorting Seashells, in which students consider the morphological characteristics of seashells to construct an evolutionary tree. Students use seashell cards as a pre-activity to explore grouping organisms by shared characteristics. As a post-activity, they construct an evolutionary tree using DNA sequences.
