The extra room provides space for air sacs, allowing birds to process the massive amounts of oxygen needed to power flight. 🐦⬛
This article in Science and Children breaks down a hands-on lesson plan geared toward second graders that tackles this misconception using scientific modeling, playful movement, and phenomena-based learning. Here is how you can recreate this 5-part investigation in your elementary classroom:
Phase 1: Hook & Challenge
Discuss & Demo: Ask what students know about bird bones, then compare a solid pool noodle…
