Procedure B: For Dinosaur Replicas

Materials:

• Calculator
• Weight scale
• Long tape measure (U.S. and/or metric markings)
• Dinosaur replicas (preferably 1/40th scale)
• Table of Cretaceous Critter Calculations
• String
• Scissors
• Ruler (U.S. and/or metric markings)

Step 1: Measure and record data for dinosaur replicas

Question 1
I. Choose dinosaur replicas for measurement and determine the scale used for each replica.

A. Choose at least three dinosaur replicas to measure.

B. Record dinosaur names on the Table of Cretaceous Critter Calculations.

C. Determine the scale used for each replica being measured. Many replicas are made using 1/40th scale.

II. Take measurements and record data.

A. Measure the length of dinosaur replicas.

1. Lay a piece of string along the length of the dinosaur from its nose to the tip of its tail. Follow the backbone, and curve the string along any bends in the neck, body, and tail.

2. Stretch the string out and measure its length with a ruler in inches or centimeters.

3. Record measurements on the Table of Cretaceous Critter Calculations. Be sure to record the unit of measurements.
