In this activity, learners play bingo to learn about the diversity of birds. This game includes a warm-up lesson and "Full Flight" version.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.
