    Deep-Sea Survival

    Explain how deep-sea animals cope with crushing pressure (no gas-filled spaces, flexible proteins, pressure-adapted enzymes); describe thermoregulation extremes…

    Ages 12 to 13Concept
  • Science // Animals of the World

    Grouping Species Using DNA

    Explain cladistics: organisms are grouped by shared derived characters, not just similarity; how phylogenetic trees are built using molecular data (DNA sequence…

    Dinosaurs Were Real

    Understand that dinosaurs were real animals that lived on Earth a very long time ago and are now extinct — none are alive today
