# Reading and Resource: # The Name Game

Dinosaurs are usually named for the people who find them, the places they’re found, or the way they look. Sometimes, though, scientists have a bit of fun with it, as you’ll see when you read about a new dinosaur called Dracorex hogwartsia.” (Sound familiar?)

To find out more about how dinosaurs are named, check out this site.

In this lesson, students investigate the hypothesis that an asteroid impact caused the extinction of the dinosaurs. In the activity, Create a Dinosaur Food Web, students use cards and construction paper connectors to create a food web from the time of the dinosaurs. Using this model, they follow the flow of energy through the food web and figure out why dinosaurs went extinct but some other animals survived.
