Let’s build a trundle wheel.
11.1 What Is a Trundle Wheel?
A tool that surveyors use to measure distances is called a trundle wheel.
How does a trundle wheel measure distance?
Why is this method of measuring distances better than the methods we used in the previous lesson?
How could we construct a simple trundle wheel? What materials would we need?
11.2 Building a Trundle Wheel
Your teacher will give you some supplies. Construct a trundle wheel and use it to measure the length of the classroom. Record:
the diameter of your trundle wheel
the number of clicks across classroom
the length of the classroom (Be prepared to explain your reasoning.)
