📚 Tips for Parents & Teachers
Use dinosaurs as a gateway to bigger science concepts. While kids are comparing T. rex to Triceratops, they're also learning about herbivores vs. carnivores, adaptation, and geological time scales. Ask follow-up questions like "Why do you think some dinosaurs were so much bigger than others?" to extend the learning.
Pair with our science tools. After exploring the Dino Timeline, check out the Rock Cycle tool to learn how fossils form, or the Animal Classification tool to see how scientists organize all living things — including dinosaurs' modern descendants, birds.
