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.

Activity Prep

In this Mystery, 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.

Prep Instructions

We recommend students work in pairs. Homeschool students can work on their own.

Each pair of students needs an area that’s about 2 feet by 3 feet for their completed food web. Plan for enough space. Students can work at desks, tables, or on the floor.

Access to a paper cutter will make your activity prep really easy.

Prepare Connector Strips

If you have access to a paper cutter, we suggest you use one to prepare these construction paper strips.

Cut the black construction paper into strips measuring 3” by ¾”.

Black Construction Strips

Cut your colored construction paper into strips measuring about 4” by ¾”.
