One species’ trash is another’s treat

Scientists have long noted that polar bears seem to leave much of their prey behind, preferring to eat only the blubber. On first glance, this might look wasteful. But abandoned portions of that carcass might actually benefit other species in the ecosystem. Practice carrying out percentile calculations while answering questions about polar-bear predation strategies, all while discussing the ecological interplay between various species in a harsh Arctic biome.

Woodpecker muscles in action

In this lesson, students will review the human muscular system and then explore how its movements compare with those of woodpeckers. Students will also examine a diagram that shows different woodpecker muscle groups and analyze data from a research article about how those muscles are used while hammering.
