A little about this puzzle

A teacher aligns a ruler with a single dinosaur tooth cast in a tray while a boy records with a pencil in a research notebook and a girl observes. A campus courtyard appears through the window. A Triceratops model stands on the sample shelf, with a magnifying glass and skeleton puzzle board on the table and a marker flag in the simulated dig box. Eight objects are distributed throughout this clean-line cartoon laboratory. The tooth and models are teaching replicas. Choose the Color or Line art image, use the picture clues to find each object, and keep the Answer key separate until you are ready to check. The three images can be printed or saved as PDF using your browser.
