Assessment: Journal Response

 Extension Activity:

 Sandbox excavation: Bury several dinosaur Lego sets in zip-lock bags in the school’s playground.  Divide the class into 3-4 teams.  Give each team a section of the playground to excavate.  Have each team locate, assemble, and identify the dinosaur they discovered.

Dinosaur Hunters: Have the students write a biography or create a multimedia presentation (PowerPoint / HyperStudio) on a famous paleontologists in history.
