Big Bite Teacher GuideBig Bite Teacher Guide Lesson: Saber-toothed Smilodon Exploration Target Grade Grades K - 2 Objective Students will explore Smilodon adaptations, create a mask with specific measurements (7 inches), and role-play "ambush predator" behaviors. Materials 1 Paper Plates (1 per student) 2 White Construction Paper 3 Rulers (1 per student) 4 Glue/Tape & Elastic String 5 "Saber-toothed Smilodon" Video Vocabulary Adaptation A special body part that helps an animal survive. Carnivore An animal that eats only meat. Ambush Predator A hunter that sneaks and surprises its prey. Fossil A trace of an ancient plant or animal. 5 MIN Warm-Up: Wide Mouth Challenge "Did you know a Smilodon could open its mouth twice as wide as a lion?" Have students sit in a circle. Ask them to open their mouths as wide as they can (without straining). Practice "extra wide" vs. "normal" bites for their snacks. Discuss: "Why would you need a giant mouth?" (To fit those giant teeth!). 5 MIN Viewing: SciShow Kids Teaching Moments: 1:28 Pause at the banana comparison. Have students hold their hands up to their faces to imagine 7-inch teeth. 2:40 Pause on "Ambush Predator." Ask: "Is a sneakier hunter better for a cat with fragile teeth?" 4:45 Critical Thinking: "How do we know Smilodons were kind to each other?" (Healed bones = someone fed them!). 20 MIN Activity: Saber Tooth Mask Math Integration: Every student must use a ruler to measure their paper "saber teeth" to exactly 7 inches before gluing. Craft Tip: Cut the paper plate in half for a "bottom-only" mask, or cut eye holes in a full plate for a full head mask. Distribute plates and construction paper. Students draw two long fangs. Measure: Use the ruler to ensure they are 7 inches long. Cut and glue the fangs to the plate. Attach elastic string. 10 MIN Role-Play: Ambush Predator Rules of the Ambush: Students wear masks and try to cross the room in complete silence. "Freeze" when the teacher (the prey) looks around. If they are loud, they must go back to the start!

Saber-Tooth Answer KeySaber-Tooth Answer Key Teacher Reference Guide Lesson Big Bite Smilodon 1. Measurement Validation Criteria for Success: Students should place the 0 mark of their ruler at the "START" line. The tip of the tooth should end as close as possible to the "STOP" line (7 inches). The tooth shape should be long, curved, and pointed (representing the canine teeth). Teacher Tip: Walk around during the activity and verify students are starting their measurement at the 0, not at the end of the ruler! 2. Brain Check Solutions What does a Smilodon eat? Plants & Berries Meat (Carnivore) How does an Ambush Predator move? Quiet & Sneaky Loud & Running Fast Discussion: The "Kindness" Evidence Referencing the video (4:45), explain to students that paleontologists found Smilodon fossils with healed broken bones. The Logic Chain: Smilodon breaks a leg or tooth. Smilodon cannot hunt for meat. Normally, it would starve. But the bone healed, which takes weeks. Conclusion: Other Smilodons must have brought it food!
