Learners investigate how animals' physical features reveal what they eat and how they survive. Students examine teeth, beaks, claws, and body shapes as adaptations that match each animal's food source, classify animals as herbivores, carnivores, or omnivores, and practice reading natural features as clues about how animals live.

Key Ideas

• An adaptation is a physical feature or behavior that helps an organism survive and get what it needs.
• Animals' teeth, beaks, and claws are adaptations shaped by the food they eat. Flat teeth grind plants; sharp teeth tear meat.
• Herbivores eat only plants, carnivores eat only animals, and omnivores eat both. Each group has adaptations suited to its diet.
• Eye placement is also an adaptation. Predators tend to have eyes facing forward for depth perception; prey animals often have eyes on the sides for wider vision.
• The body features of an extinct animal, like a fossil, can reveal what it ate the same way a living animal's features can.

Vocabulary

• Adaptation: A physical feature or behavior that helps an organism survive and get energy.
• Herbivore: An animal that eats only plants.
• Carnivore: An animal that eats only other animals.
• Omnivore: An animal that eats both plants and animals.
• Predator: An animal that hunts and eats other animals.
• Prey: An animal that is hunted and eaten by a predator.

Hands-On Activity: Mystery Animal Diet Challenge

Supply List

• Paper and pencil
• The Animal Feature Card set below (read aloud or write on slips of paper)

Animal Feature Cards (read one at a time):

• Animal A: Long, flat molars at the back of the jaw. Eyes on the sides of the head. Four stomachs.
• Animal B: Long curved talons, a sharp hooked beak, and eyes that face forward.
• Animal C: Short, rounded teeth across the whole jaw. Eyes face forward. Hands with opposable thumbs.
• Animal D: A long, tube-like mouth with no teeth. A sticky 12-inch-long tongue.
• Animal E: Broad, flat bill with small ridges along the edges. Webbed feet.

Instructions

• For each Animal Card, read the features aloud and give students one minute to decide: herbivore, carnivore, or omnivore? Write their prediction and the feature that was the biggest clue.
• After all five predictions, reveal the answers: A = herbivore (cow), B = carnivore (hawk), C = omnivore (human or monkey), D = carnivore (anteater, eats insects), E = omnivore (duck).
• Compare predictions to answers. Which features were the most reliable clues? Which were misleading?
• Finally, have students describe an animal of their own invention — making up features that would indicate a specific diet. Share with the group and see if others can identify the diet from the features alone.
