1. Start With Wonder: By Land or by Sea?
A hummingbird flaps its wings 75 times per second during flight, and typically eats every 15 minutes. When hummingbirds migrate, do you think they fly over land and feed on flowers along the way? Or do they fly over open seas, where there's no place to find food or rest? Have students look at the map and share predictions. |
